Add VESA mode support for syscons, which enables the support of 15, 16, 24, and 32 bit modes. To use that, syscons(4) must be built with the compile time option 'options SC_PIXEL_MODE', and VESA support (a.k.a. vesa.ko) must be either loaded, or be compiled into the kernel. Do not return EINVAL when the mouse state is changed to what it already is, which seems to cause problems when you have two mice attached, and applications are not likely obtain useful information through the EINVAL caused by showing the mouse pointer twice. Teach vidcontrol(8) about mode names like MODE_<NUMBER>, where <NUMBER> is the video mode number from the vidcontrol -i mode output. Also, revert the video mode if something fails.

Update for the KDB framework. Sanitize the alpha console code now that it's in the way even more. Basicly: remove all alpha specific console support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console initialization to be identical to all other platforms. In a nutshell: call cninit(). The platform specific code now only sets or clears RB_SERIAL and thus automaticly causes the right console to be selected. sio.c: o Replace the remote GDB hacks and use the GDB debug port interface instead. o Make debugging code conditional upon KDB instead of DDB. o Call kdb_alt_break() instead of db_alt_break(). o Call kdb_enter() instead of breakpoint(). o Remove the ugly compatibility of using the console as the debug port.

Colorize syscons kernel console output according to a table indexed by the CPU number. This was originally for debugging near-deadlock conditions where multiple CPUs either deadlock or scramble each other's output trying to report the problem, but I found it interesting and sometimes useful for ordinary kernel messages. Ordinary kernel messages shouldn't be interleaved, but if they are then the colorization makes them readable even if the interleaving is for every character (provided the CPU printing each message doesn't change). The default colors are 8-15 starting at 15 (bright white on black) for CPU 0 and repeating every 8 CPUs. This works best with 8 CPUs. Non-bright colors and nonzero background colors need special configuration to avoid unreadable and ugly combinations so are not configured by default. The next bright color after 15 is 8 (bright black = dark gray) is not very readable but is the only other color used with 2 CPUs. After that the next bright color is 9 (bright blue) which is not much brighter than bright black, but is used with 3+ CPUs. Other bright colors are brighter. Colorization is configured by default so that it gets tested. It can only be turned off by configuring SC_KERNEL_CONS_ATTR to anything other than FG_WHITE. After booting, all colors can be changed using the syscons.kattr sysctl. This is a SYSCTL_OPAQUE, and no utility is provided to change it (sysctl only displays it). The default colors work in all VGA modes that I could test. In 2-color graphics modes, all 8 bright colors are displayed as bright white, so the colorization has no effect, but anything with a nonzero background gives white on white unless the foreground is zero. I don't have an mono or VGA grayscale hardware to test on. Support for mono mode seems to have never worked right in syscons (I think bright white gives white underline with either bold or bright), but VGA grayscale should work better than 2-color graphics.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Finished device configuration database work for all ISA devices (except `ze') and all SCSI devices (except that it's not done quite the way I want). New information added includes: - A text description of the device - A ``state''---unknown, unconfigured, idle, or busy - A generic parent device (with support in the m.i. code) - An interrupt mask type field (which will hopefully go away) so that . ``doconfig'' can be written This requires a new version of the `lsdev' program as well (next commit).

Fix bugs in (mostly) not-yet-activated parts of early/emergency output: - map the hard-coded frame buffer address above KERNBASE. Using the physical address only worked because of larger mapping bugs. The hard-coded frame buffer address only works on x86. Use messy ifdefs to try to avoid warnings about unused code for other arches. - remove the sysctl for reading and writing the table kernel console attributes. Writing only worked for emergency output since normal output uses unalterd copies. - fix the test for the emergency console being usable - explain why a hard-coded attribute is used very early. Emergency output works on x86 even before the pcpu pointer is initialized.

The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Pass 3 of the great devsw changes most devsw referenced functions are now static, as they are in the same file as their devsw structure. I've also added DEVFS support for nearly every device in the system, however many of the devices have 'incorrect' names under DEVFS because I couldn't quickly work out the correct naming conventions. (but devfs won't be coming on line for a month or so anyhow so that doesn't matter) If you "OWN" a device which would normally have an entry in /dev then search for the devfs_add_devsw() entries and munge to make them right.. check out similar devices to see what I might have done in them in you can't see what's going on.. for a laugh compare conf.c conf.h defore and after... :) I have not doen DEVFS entries for any DISKSLICE devices yet as that will be a much more complicated job.. (pass 5 :) pass 4 will be to make the devsw tables of type (cdevsw * ) rather than (cdevsw) seems to work here.. complaints to the usual places.. :)

1. Reorganized screen saver related code so that both the LKM screen saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.

Colorize syscons kernel console output according to a table indexed by the CPU number. This was originally for debugging near-deadlock conditions where multiple CPUs either deadlock or scramble each other's output trying to report the problem, but I found it interesting and sometimes useful for ordinary kernel messages. Ordinary kernel messages shouldn't be interleaved, but if they are then the colorization makes them readable even if the interleaving is for every character (provided the CPU printing each message doesn't change). The default colors are 8-15 starting at 15 (bright white on black) for CPU 0 and repeating every 8 CPUs. This works best with 8 CPUs. Non-bright colors and nonzero background colors need special configuration to avoid unreadable and ugly combinations so are not configured by default. The next bright color after 15 is 8 (bright black = dark gray) is not very readable but is the only other color used with 2 CPUs. After that the next bright color is 9 (bright blue) which is not much brighter than bright black, but is used with 3+ CPUs. Other bright colors are brighter. Colorization is configured by default so that it gets tested. It can only be turned off by configuring SC_KERNEL_CONS_ATTR to anything other than FG_WHITE. After booting, all colors can be changed using the syscons.kattr sysctl. This is a SYSCTL_OPAQUE, and no utility is provided to change it (sysctl only displays it). The default colors work in all VGA modes that I could test. In 2-color graphics modes, all 8 bright colors are displayed as bright white, so the colorization has no effect, but anything with a nonzero background gives white on white unless the foreground is zero. I don't have an mono or VGA grayscale hardware to test on. Support for mono mode seems to have never worked right in syscons (I think bright white gives white underline with either bold or bright), but VGA grayscale should work better than 2-color graphics.

Fix missing switching of the terminal emulator when switching the terminal state for kernel console output. r56043 in 2000 added many complications to support dynamic selection of the terminal emulator using modules and the ioctl CONS_SETTERM. This was never completed. There are still no modules, but it is easy to restore the scterm and dumb emulators at compile time. Then boot-time configuration for the preferred one doesn't work right, but CONS_SETTERM almost works after fixing this bug. CONS_SETTERM only switches the emulator for the user state, leaving the kernel state(s) still using the boot-time emulator. The fix is especially important when switching from sc to scteken, since the scteken state has pointers in it. Rename kernel_console_ts to sc_kts.

1. Reorganized screen saver related code so that both the LKM screen saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Change the way moused talk to syscons, now its only delivering mouseevents via an ioctl (MOUSE_ACTION). Fixed a couple of bugs (destructive cursor, uncut, jitter). Now applications can use the mouse via the MOUSE_MODE ioctl, its possible to have a signal sent on mouseevents, makeing an event loop in the application take over mouseevents.

Integrate kbdmux(4) into syscons(4) and kbd code. By default syscons(4) will look for the kbdmux(4) keyboard first, and then, if not found, look for any keyboard. Current kbd code is modified so if kbdmux(4) is the current keyboard, all new keyboards are automatically added to the kbdmux(4). Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at the loader prompt, or at runtime, by kldload'ing the kbdmux module and releasing current active keyboard. If, for whatever reason, kbdmux(4) is not required/desired then just do not load it and everything should work as before. It is also possible to kldunload kbdmux at runtime and syscons(4) will automatically switch to the first available keyboard. No response from: freebsd-current@ MFC after: 1 day

The first stage of console driver reorganization: activate new keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

static void sc_puts(scr_stat *scp, u_char *buf, int len);
Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Turn consolectl into a simple device node, not a TTY. Apart from the 16 virtual terminals, Syscons allocates two device nodes that should not really be TTYs, even though they are. One of them is consolectl. In RELENG_7 and before, these device nodes are used in single user mode. After I simplified input path, we only use this device node to call ioctl() on (moused, Xorg, vidcontrol). When you call ioctl() on consolectl, it will behave the same as being called on the first window.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Turn consolectl into a simple device node, not a TTY. Apart from the 16 virtual terminals, Syscons allocates two device nodes that should not really be TTYs, even though they are. One of them is consolectl. In RELENG_7 and before, these device nodes are used in single user mode. After I simplified input path, we only use this device node to call ioctl() on (moused, Xorg, vidcontrol). When you call ioctl() on consolectl, it will behave the same as being called on the first window.

Implement ec_putc() (emergency kernel [syscons] console putc()) and use it in emergency in sc_cnputc(). Locking fixes in sc_cnputc() previously turned off normal output in near-deadlock conditions and added deferred output which might never be completed. Emergency output goes to the frame buffer using sufficiently atomic non-blocking writes if the console is in text mode (in graphics mode, nothing is done, modulo races setting the graphics mode bit). Screen updates overwrite the emergency output if the emergency condition clears enough to reach them. ec_putc() also works for "early" console output in normal x86 text mode as soon as this mode is initialized (if ever). This uses a hard-coded x86 frame buffer address before cninit() and a hopefully MI address after cninit(). But non-x86 is more likely to not support text mode, when ec_putc() will be null. ec_putc() has no dependencies of syscons before cninit(), and only has them later to track syscons' mode changes. This commit doesn't attach ec_putc() for early use. To test emergency use, put a breakpoint in central syscons output code like sc_puts() and do some user output. The system used to race or deadlock in ddb output soon after entry to ddb. The locking fixes deferred the output until after leaving ddb, so ddb was unusable and you had to try typing c[ontinue] blindly until it exited, or better use a serial console in parallel. Now the output goes to a window in the middle 2/3 of the screen. Scrolling is circular and there is no cursor, but otherwise ec_putc() provides full dumb terminal functionality and very fast output that hides artificates from dumb overwrites.

If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe.

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Less-quick fix for locking fixes in r172250. r172250 added a second syscons spinlock for the output routine alone. It is better to extend the coverage of the first syscons spinlock added in r162285. 2 locks might work with complicated juggling, but no juggling was done. What the 2 locks actually did was to cover some of the missing locking in each other and deadlock less often against each other than a single lock with larger coverage would against itself. Races are preferable to deadlocks here, but 2 locks are still worse since they are harder to understand and fix. Prefer deadlocks to races and merge the second lock into the first one. Extend the scope of the spinlocking to all of sc_cnputc() instead of just the sc_puts() part. This further prefers deadlocks to races. Extend the kdb_active hack from sc_puts() internals for the second lock to all spinlocking. This reduces deadlocks much more than the other changes increases them. The s/p,10* test in ddb gets much further now. Hide this detail in the SC_VIDEO_LOCK() macro. Add namespace pollution in 1 nested #include and reduce namespace pollution in other nested #includes to pay for this. Move the first lock higher in the witness order. The second lock was unnaturally low and the first lock was unnaturally high. The second lock had to be above "sleepq chain" and/or "callout" to avoid spurious LORs for visual bells in sc_puts(). Other console driver locks are already even higher (but not adjacent like they should be) except when they are missing from the table. Audio bells also benefit from the syscons lock being high so that audio mutexes have chance of being lower. Otherwise, console drviver locks should be as low as possible. Non-spurious LORs now occur if the bell code calls printf() or is interrupted (perhaps by an NMI) and the interrupt handler calls printf(). Previous commits turned off many bells in console i/o but missed ones done by the teken layer.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Turn consolectl into a simple device node, not a TTY. Apart from the 16 virtual terminals, Syscons allocates two device nodes that should not really be TTYs, even though they are. One of them is consolectl. In RELENG_7 and before, these device nodes are used in single user mode. After I simplified input path, we only use this device node to call ioctl() on (moused, Xorg, vidcontrol). When you call ioctl() on consolectl, it will behave the same as being called on the first window.

Last minute TTY API change: remove mutex argument from tty_alloc(). I don't want people to override the mutex when allocating a TTY. It has to be there, to keep drivers like syscons happy. So I'm creating a tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex() should eventually be removed. The advantage of this approach, is that we can just remove a function, without breaking the regular API in the future.

If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

/* Create device node. */
Turn consolectl into a simple device node, not a TTY. Apart from the 16 virtual terminals, Syscons allocates two device nodes that should not really be TTYs, even though they are. One of them is consolectl. In RELENG_7 and before, these device nodes are used in single user mode. After I simplified input path, we only use this device node to call ioctl() on (moused, Xorg, vidcontrol). When you call ioctl() on consolectl, it will behave the same as being called on the first window.

Add new function ttyinitmode() which sets our systemwide default modes on a tty structure. Both the ".init" and the current settings are initialized allowing the function to be used both at attach and open time. The function takes an argument to decide if echoing should be enabled. Echoing should not be enabled for regular physical serial ports unless they are consoles, in which case they should be configured by ttyconsolemode() instead. Use the new function throughout.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Fix missing switching of the terminal emulator when switching the terminal state for kernel console output. r56043 in 2000 added many complications to support dynamic selection of the terminal emulator using modules and the ioctl CONS_SETTERM. This was never completed. There are still no modules, but it is easy to restore the scterm and dumb emulators at compile time. Then boot-time configuration for the preferred one doesn't work right, but CONS_SETTERM almost works after fixing this bug. CONS_SETTERM only switches the emulator for the user state, leaving the kernel state(s) still using the boot-time emulator. The fix is especially important when switching from sc to scteken, since the scteken state has pointers in it. Rename kernel_console_ts to sc_kts.

The switch to kernel terminal context needs to update more than the cursor position. Especially the screen size, and potentially everything except the input state and attributes. Do this by changing the cursor position setting method to a general syncing method. Use proper constructors instead of copying to create kernel terminal contexts. We really want clones and not new instances, but there is no method for cloning and there is nothing in the active instance that needs to be cloned exactly. Add proper destructors for kernel terminal contexts. I doubt that the destructor code has every been reached, but if it was then it leaked the memory of the clones. Remove freeing of statically allocated memory for the non-kernel terminal context for the same terminal as the kernel. This is in the nearly unreachable code. This used to not happen because delicate context swapping made the user context use the dynamic memory and kernel context the static memory. I didn't restore this swapping since it would have been unnatural to have all kernel contexts except 1 dynamic. The constructor for terminal context has bad layering for reasons related to the bug. It has to return static memory early before malloc() works. Callers also can't allocate memory until after the first constructor selects an emulator and tells upper layers the size of its context. After that, the cloning hack required the cloning code to allocate the memory, but for all other constructors it would be better for the terminal layer to allocate and deallocate the memory in all cases. Zero the memory when allocating terminal contexts dynamically.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Next syscons update (given up on numbering :) Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

hook userland threads suspend + resume into acpi suspend code Also, split power_suspend into power_suspend and power_suspend_early. power_suspend_early is called before the userland is frozen. power_suspend is called after the userland is frozen. Currently only VT switching is hooked to power_suspend_early. This is needed because switching away from X server requires its cooperation, so obviously X server must not be frozen when that happens. Freezing userland during ACPI suspend is useful because not all drivers correctly handle suspension concurrent with other activity. This is especially applicable to drivers ported from other operating systems that suspend all software activity between placing drivers and hardware into suspended state. In particular drm2/radeon (radeonkms) depends on the described procedure. The driver does not have any internal synchronization between suspension activities and processing of userland requests. Many thanks to kib for the code that allows to freeze and thaw all userland threads. Note that ideally we also need to park / inhibit (non-special) kernel threads as well to ensure that they do not call into drivers. MFC after: 17 days

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV. When this key is pressed, the vty immediately before the current vty will become foreground. Analogue to PREV, which is usually assigned to the PrntScrn key. PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen. Submitted by: Nick Hibma (n_hibma@FreeBSD.ORG) SC_DFLT_FONT makeoptions "SC_DFLT_FONT=_font_name_" Include the named font as the default font of syscons. 16-line, 14-line and 8-line font data will be compiled in. This option replaces the existing STD8X16FONT option, which loads 16-line font data only. - The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c. - The video driver provides a set of ioctl commands to manipulate the frame buffer. - New kernel configuration option: VGA_WIDTH90 Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are mot always supported by the video card. PR: i386/7510 Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx. - The header file machine/console.h is reorganized; its contents is now split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h (another new file). machine/console.h is still maintained for compatibility reasons. - Kernel console selection/installation routines are fixed and slightly rebumped so that it should now be possible to switch between the interanl kernel console (sc or vt) and a remote kernel console (sio) again, as it was in 2.x, 3.0 and 3.1. - Screen savers and splash screen decoders Because of the header file reorganization described above, screen savers and splash screen decoders are slightly modified. After this update, /sys/modules/syscons/saver.h is no longer necessary and is removed.

- Hang the scr_stat struct from dev_t. - Remove sc_get_scr_stat(). It's not necessary anymore. - Call ttymalloc() to allocate the struct tty for each vty, rather than statically declaring an array of struct tty. We still need a statically allocated struct tty for the first vty which is used for the kernel console I/O, though. - Likewise, call ttymalloc() for /dev/sysmouse and /dev/consolectl. - Delete unnecessary test on the pointer struct tty *tp in some functions. - Delete unused code in scmouse.c.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

After this update, /sys/modules/syscons/saver.h is no longer necessary and is removed.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Reorganise a little to prepare for locking fixes: - in sccnopen(), open the keyboard before the screen. The keyboard currently requires Giant (although it must be spinlocked to work correctly as a console), so the previous order would be a LOR if it has any semblance of locking. - add a (currently dummy) state arg to scgetc().

Make syscons(4) use ttyv0 instead of consolectl as its primary window. When I was hacking on uart(4) to make it work with the MPSAFE TTY layer, I noticed there was a difference between the way syscons and uart work with respect to consoles: - The uart(4) driver sets cn_name to the corresponding ttyu%r node, which means init(8) (which opens /dev/console) will have its output redirected to /dev/ttyu%r. After /etc/rc is done, it can spawn a getty on that device node as well. - Syscons used a little different approach. Apart from the /dev/ttyv%r nodes, it creates a /dev/consolectl node. This device node is used by moused and others to deliver their data, but for some reason it also acts as a TTY, which shares its stat structure with ttyv0. This device node is used as a console (run conscontrol). There are a couple advantages of this approach: - Because we use two different TTY's to represent the 0th syscons window, we allocate two sets of TTY buffers. Even if you don't use /dev/consolectl after the system has booted (systems that don't run moused), it seems the buffers are still allocated. - We have to apply an evil hack to redirect input to /dev/consolectl. Because each window (stat) is associated not associated with one TTY, syscons solves this by redirecting all input to closed TTY's to consolectl. This means that opening /dev/ttyv0 while in single user mode will probably cause strange things to happen with respect to keyboard input redirection. The first patch that I discussed with philip@ turned consolectl into a symlink to ttyv0, but this was not a good idea, because in theory we would want consolectl to be a simple device node, which contains all the `privileged' ioctl()'s. Apart from that, it didn't work, because each time /dev/ttyv0 got revoked, moused also lost its descriptor to deliver input, which meant you had to plug out/in your mouse to make it work again. This version just leaves the consolectl device the way it is. It can still be used to write output to ttyv0, but it can no longer receive any input. In my opinion this patch is not a complete solution, but it's already a step in the good direction. It would allow us to turn consolectl into a special (non-TTY) device node in the far future. It shaves off 15 KB of wasted TTY buffer space. Discussed with: philip

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

The base field holds user data translated in a reversible way and is needed because current field holds this in an irreversible way for efficiency. Factor out some common code for the reversible translation. This is slightly simpler now, and much easier to expand. Translate the magic flags value -1 to a single control flag internally up front so other flags can be trusted later. This can be used for the relevant ioctl() too. Remove CONS_CURSOR_FLAGS which contained all the control flags. It was unused and not useful. After adding more flags, there will be tests on a couple at a time but never on them all. This API should have used this to disallow unknown flags.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV. When this key is pressed, the vty immediately before the current vty will become foreground. Analogue to PREV, which is usually assigned to the PrntScrn key. PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen. Submitted by: Nick Hibma (n_hibma@FreeBSD.ORG) SC_DFLT_FONT makeoptions "SC_DFLT_FONT=_font_name_" Include the named font as the default font of syscons. 16-line, 14-line and 8-line font data will be compiled in. This option replaces the existing STD8X16FONT option, which loads 16-line font data only. - The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c. - The video driver provides a set of ioctl commands to manipulate the frame buffer. - New kernel configuration option: VGA_WIDTH90 Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are mot always supported by the video card. PR: i386/7510 Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx. - The header file machine/console.h is reorganized; its contents is now split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h (another new file). machine/console.h is still maintained for compatibility reasons. - Kernel console selection/installation routines are fixed and slightly rebumped so that it should now be possible to switch between the interanl kernel console (sc or vt) and a remote kernel console (sio) again, as it was in 2.x, 3.0 and 3.1. - Screen savers and splash screen decoders Because of the header file reorganization described above, screen savers and splash screen decoders are slightly modified. After this update, /sys/modules/syscons/saver.h is no longer necessary and is removed.

- Add support for the following mice to psm/moused/sysmouse: MS IntelliMouse, Kensington Thinking Mouse, Genius NetScroll, Genius NetMouse, Genius NetMouse Pro, ALPS GlidePoint, ASCII MieMouse, Logitech MouseMan+, FirstMouse+ - The `psm' driver is made to recognize various models of PS/2 mice and enable their extra features so that their additional buttons and wheel/roller are recognized. The name of the detected model will be printed at boot time. - A set of new ioctl functions are added to the `psm', `mse' and `sysmouse' drivers so that the userland program (such as the X server) can query device information and change driver settings. - The wheel/roller movement is handled as the `Z' axis movement by the mouse drivers and the moused daemon. The Z axis movement may be mapped to another axis movement or buttons. - The mouse drivers support a new, standard mouse data format, MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement and up to 10 buttons. /sys/i386/include/mouse.h - Added some fields to `mousestatus_t' to store Z axis movement and flag bits. - Added the field `model' to `mousehw_t' to store mouse model code. Defined model codes. - Extended `mousemode_t'. - Added new protocols and some constants for them. - Added new ioctl functions and structures. - Removed obsolete ioctl definitions. /sys/i386/include/console.h - Added `dz' field to the structure `mouse_data' to pass Z axis movement to `syscons/sysmouse'. - Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON. Use button bits defined in `mouse.h' instead. /sys/i386/isa/psm.c - Added a set of functions to detect various mice which have additional features (wheel and buttons) unavailable in the standard PS/2 mouse. - Refined existing ioctl functions and added new ones. Most important of all is MOUSE_SETLEVEL which manipulates the output level of the driver. While the output level remains zero, the output from the `psm' driver is in the standard PS/2 mouse format (three bytes long). When the level is set to one, the `psm' driver will send data in the extended format. At the level two the driver uses the format which is native to the connected mouse is used. (Meaning that the output from the device is passed to the caller as is, unmodified.) The `psm' driver will pass such extended data format as is to the caller if the output level is two, but emulates the standard format if the output level is zero. - Added kernel configuration flags to set initial resolution (PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL). - Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION. Acceleration ratio is now specified by the kernel configuration flags stated above. Sync check logic is refined and now standard. The sync check can be turned off by the new kernel configuration flags PSM_CONFIG_NOCHECKSYNC (0x100). PSM_EMULATION has been of little use. - Summer clean up :-) Removed unused code and obsolete comments. /sys/i386/isa/mse.c - Created mseioctl() to deal with ioctl functions MOUSE_XXXX. Most importantly, the MOUSE_SETLEVEL ioctl will change the output format from the 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Use constants defined in `mouse.h' rather than magic numbers. /sys/i386/isa/syscons.c - Changed scioctl() to reflect the new `console.h' and some of the new ioctls defined in `mouse.h'. Most importantly, the MOUSE_SETLEVEL ioctl will change the `sysmouse' output format from the MouseSystems 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Added support for double/triple click actions of the left button and single click action of the right button in the virtual console. The left button double click will select a word under the mouse pointer. The triple click will select a line and the single click of the right button will extend the selected region to the current position of the mouse pointer. This will make the cut/paste support more compatible with xterm. /sys/i386/isa/kbdio.h - Added PSM_INTELLI_ID.

Fix our ioctl(2) implementation when the argument is "int". New ioctls passing integer arguments should use the _IOWINT() macro. This fixes a lot of ioctl's not working on sparc64, most notable being keyboard/syscons ioctls. Full ABI compatibility is provided, with the bonus of fixing the handling of old ioctls on sparc64.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

1) font loading (two fixes) When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Fix setting of defaults for the text cursor.

The global defaults field was also invariant after boot time, but not quite so useless. Fix this by adding a second selection bit the the control flags of the relevant ioctl(). vidcontrol doesn't support this yet.

Fixes annoying behavior and a bug regarding the destructive cursor (CHAR_CURSOR) 1. Reduced the number of calls to set_destructive_cursor(). The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

Support setting the colors of cursors for the VGA renderer. Advertise this by changing the defaults to mostly red. If you don't like this, change them (almost) back using: vidcontrol -c charcolors,base=7,height=0 vidcontrol -c mousecolors,base=0[,height=15] The (graphics mode only) mouse cursor colors were hard-coded to a black border and lightwhite interior. Black for the border is the worst possible default, since it is the same as the default black background and not good for any dark background. Reversing this gives the better default of X Windows. Coloring everything works better still. Now the coloring defaults to a lightwhite border and red interior. Coloring for the character cursor is more complicated and mode dependent. The new coloring doesn't apply for hardware cursors. For non-block cursors, it only applies in graphics mode. In text mode, the cursor color was usually a hard-coded (dull)white for the background only, unless the foreground was white when it was a hard-coded black for the background only, unless the foreground was white and the background was black it was reverse video. In graphics mode, it was always reverse video for the block cursor. Reverse video is worse, especially over cutmarking regions, since cutmarking still uses simple reverse video (nothing better is possible in text mode) and double reverse video for the cursor gives normal video. Now, graphics mode uses the same algorithm as the best case for text mode in all cases for graphics mode. The hard-coded sequence { white, black, } for the background is now { red, white, blue, } where the first 2 colors can be configured. The blue color at the end is a sentinel which prevents reverse video being used in most cases but breaks the compatibility setting for white on black and black on white characters. This will be fixed later. The compatibility setting is most needed for mono modes. The previous commit to syscons.c changed sc_cnterm() to be more careful. It followed null pointers in some cases. But sc_cnterm() has been unreachable for 15+ years since changes for multiple consoles turned off calls to the the cnterm destructor for all console drivers. Before them, it was only called at boot time. So no driver with an attached console has ever been unloadable and not even the non-console destructors have been tested much.

Added support for many more videomodes, including graphic modes up til 320x200 256col VGA. This is nessesary for the iBCS stuff to work right. (And we get the benefit of more video modes). Uses the videocard BIOS to optain mode tables. Added a "green" saver, switches off the syncs for "green" monitors. Reviewed by: Submitted by: Obtained from:

First round in syscons update. Several new features has been added: No kernel config options anymore besides keyboard language layout. Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV.

PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons.

Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode. The 80x25 text will be displayed on the 800x600 screen. Useful for some laptop computers. vidcontrol accepts the new `-i <info>' option, where <info> must be either `adapter' or `mode'. When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter. When the `-i mode' option is specified, vidcontrol will list video modes which are actually supported by the video adapter. Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

1. Reorganized screen saver related code so that both the LKM screen saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV. When this key is pressed, the vty immediately before the current vty will become foreground. Analogue to PREV, which is usually assigned to the PrntScrn key. PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen.

This option replaces the existing STD8X16FONT option, which loads 16-line font data only. - The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c. - The video driver provides a set of ioctl commands to manipulate the frame buffer. - New kernel configuration option: VGA_WIDTH90 Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are mot always supported by the video card. PR: i386/7510 Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx. - The header file machine/console.h is reorganized; its contents is now split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h (another new file). machine/console.h is still maintained for compatibility reasons. - Kernel console selection/installation routines are fixed and slightly rebumped so that it should now be possible to switch between the interanl kernel console (sc or vt) and a remote kernel console (sio) again, as it was in 2.x, 3.0 and 3.1. - Screen savers and splash screen decoders Because of the header file reorganization described above, screen savers and splash screen decoders are slightly modified. After this update, /sys/modules/syscons/saver.h is no longer necessary and is removed.

Next syscons update (given up on numbering :) Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Add VESA support to syscons. Kazu writes: The VESA support code requires vm86 support. Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode. The 80x25 text will be displayed on the 800x600 screen. Useful for some laptop computers. vidcontrol accepts the new `-i <info>' option, where <info> must be either `adapter' or `mode'. When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter. When the `-i mode' option is specified, vidcontrol will list video modes which are actually supported by the video adapter. Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV. When this key is pressed, the vty immediately before the current vty will become foreground. Analogue to PREV, which is usually assigned to the PrntScrn key. PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen.

You shouldn't see any functional change by this commit; this is only internal code reorganization.

Fix our ioctl(2) implementation when the argument is "int". New ioctls passing integer arguments should use the _IOWINT() macro. This fixes a lot of ioctl's not working on sparc64, most notable being keyboard/syscons ioctls. Full ABI compatibility is provided, with the bonus of fixing the handling of old ioctls on sparc64.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

The first stage of console driver reorganization: activate new keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Restore binary compatibility for GIO_KEYMAP and PIO_KEYMAP. Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls to support wide characters. I created a patch to add ABI compatibility for the old calls, but I didn't get any feedback to that. It seems now people are upgrading from 8 to 9 they experience this issue, so add it anyway.

Remove explicit calls to keyboard methods with their respective variants implemented with macros. This patch improves code readability. Reasoning behind kbdd_* is a "keyboard discipline". List of macros is supposed to be complete--all methods of keyboard_switch should have their respective macros from now on. Functionally, this code should be no-op. My intention is to leave current behaviour of code as is. Glanced at by: rwatson Reviewed by: emax, marcel Approved by: cognet

Added accent (dead) key support to syscons and kbdcontrol. With a keymap with accent key definitions loaded to syscons, you press an accent key followed by a regular letter key to produce an accented letter. Press an accent key followed by the space bar to get the accent letter itself. Code is based on the ideas and work by jmrueda@diatel.upm.es and totii@est.is. PR: i386/4016 console.h - Defined structures and constants for accent (dead) keys. syscons.c, kbdtables.h - When an accent key is pressed, set the corresponding index to `accents'. If the next key is the space key, produce the accent char itself. Otherwise search the accent key map entry, indexed by `accents', for a matching pair of a regular char and an accented char. - Added ioctl functions to set and get the accent key map (PIO_DEADKEYMAP and GIO_DEADKEYMAP).

More fixes to deal with fonts: - Set the correct value scp->font_size in init_scp(). - Set scp->font_size to FONT_NONE for VGA_MODEX. Interim fix for a font problem: - A kludge to display the correct font on some video cards. We should be able to load multiple fonts to the VGA plane #2 and switch between fonts by setting the font select register in the VGA sequencer. It appears that the current code isn't functioning as expected on some VGA cards (I have reports on Millenium and Mach64 cards). This is either a bug in syscons or a hardware compatibility problem ;-< This kludge will always load only one font set at a time and always use the font page #0 on the plane #2. It is an interim kludge until we find the exact cause and solution. Small adjustment for mouse cursor handling: - Turn off the mouse cursor early when changing video modes. Video mode switch fixes: - Stop the screen saver when changing video modes. - Enclose the critical section with a pair of spltty()/splx(). - A kludge to prevent scrn_update() from accessing video memory in less- critical sections in video mode change; artificially turn on the UNKNOWN_MODE flag.

Add a font width argument to vi_load_font_t, vi_save_font_t and vi_putm_t and do some preparations for handling 12x22 fonts (currently lots of code implies and/or hardcodes a font width of 8 pixels). This will be required on sparc64 which uses a default font size of 12x22 in order to add font loading and saving support as well as to use a syscons(4)-supplied mouse pointer image. This API breakage is committed now so it can be MFC'ed in time for 6.0 and later on upcoming framebuffer drivers destined for use on sparc64 and which are expected to rely on using font loading internally and on a syscons(4)-supplied mouse pointer image can be easily MFC'ed to RELENG_6 rather than requiring a backport.

Add a font width argument to vi_load_font_t, vi_save_font_t and vi_putm_t and do some preparations for handling 12x22 fonts (currently lots of code implies and/or hardcodes a font width of 8 pixels). This will be required on sparc64 which uses a default font size of 12x22 in order to add font loading and saving support as well as to use a syscons(4)-supplied mouse pointer image. This API breakage is committed now so it can be MFC'ed in time for 6.0 and later on upcoming framebuffer drivers destined for use on sparc64 and which are expected to rely on using font loading internally and on a syscons(4)-supplied mouse pointer image can be easily MFC'ed to RELENG_6 rather than requiring a backport. Tested on: i386, sparc64, make universe MFC after: 1 week

Add a font width argument to vi_load_font_t, vi_save_font_t and vi_putm_t and do some preparations for handling 12x22 fonts (currently lots of code implies and/or hardcodes a font width of 8 pixels). This will be required on sparc64 which uses a default font size of 12x22 in order to add font loading and saving support as well as to use a syscons(4)-supplied mouse pointer image. This API breakage is committed now so it can be MFC'ed in time for 6.0 and later on upcoming framebuffer drivers destined for use on sparc64 and which are expected to rely on using font loading internally and on a syscons(4)-supplied mouse pointer image can be easily MFC'ed to RELENG_6 rather than requiring a backport.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Turn consolectl into a simple device node, not a TTY. Apart from the 16 virtual terminals, Syscons allocates two device nodes that should not really be TTYs, even though they are. One of them is consolectl. In RELENG_7 and before, these device nodes are used in single user mode. After I simplified input path, we only use this device node to call ioctl() on (moused, Xorg, vidcontrol). When you call ioctl() on consolectl, it will behave the same as being called on the first window.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

The syscons driver doesn't really check the presence of the display adapter during the system boot. It always assumes there is at least a monochrome adapter. This is rather strange assumption. If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg.

/* initialize required fields */
Make syscons(4) use ttyv0 instead of consolectl as its primary window. When I was hacking on uart(4) to make it work with the MPSAFE TTY layer, I noticed there was a difference between the way syscons and uart work with respect to consoles: - The uart(4) driver sets cn_name to the corresponding ttyu%r node, which means init(8) (which opens /dev/console) will have its output redirected to /dev/ttyu%r. After /etc/rc is done, it can spawn a getty on that device node as well. - Syscons used a little different approach. Apart from the /dev/ttyv%r nodes, it creates a /dev/consolectl node. This device node is used by moused and others to deliver their data, but for some reason it also acts as a TTY, which shares its stat structure with ttyv0. This device node is used as a console (run conscontrol). There are a couple advantages of this approach: - Because we use two different TTY's to represent the 0th syscons window, we allocate two sets of TTY buffers. Even if you don't use /dev/consolectl after the system has booted (systems that don't run moused), it seems the buffers are still allocated. - We have to apply an evil hack to redirect input to /dev/consolectl. Because each window (stat) is associated not associated with one TTY, syscons solves this by redirecting all input to closed TTY's to consolectl. This means that opening /dev/ttyv0 while in single user mode will probably cause strange things to happen with respect to keyboard input redirection. The first patch that I discussed with philip@ turned consolectl into a symlink to ttyv0, but this was not a good idea, because in theory we would want consolectl to be a simple device node, which contains all the `privileged' ioctl()'s. Apart from that, it didn't work, because each time /dev/ttyv0 got revoked, moused also lost its descriptor to deliver input, which meant you had to plug out/in your mouse to make it work again. This version just leaves the consolectl device the way it is. It can still be used to write output to ttyv0, but it can no longer receive any input. In my opinion this patch is not a complete solution, but it's already a step in the good direction. It would allow us to turn consolectl into a special (non-TTY) device node in the far future. It shaves off 15 KB of wasted TTY buffer space. Discussed with: philip

The switch to kernel terminal context needs to update more than the cursor position. Especially the screen size, and potentially everything except the input state and attributes. Do this by changing the cursor position setting method to a general syncing method. Use proper constructors instead of copying to create kernel terminal contexts. We really want clones and not new instances, but there is no method for cloning and there is nothing in the active instance that needs to be cloned exactly. Add proper destructors for kernel terminal contexts. I doubt that the destructor code has every been reached, but if it was then it leaked the memory of the clones. Remove freeing of statically allocated memory for the non-kernel terminal context for the same terminal as the kernel. This is in the nearly unreachable code. This used to not happen because delicate context swapping made the user context use the dynamic memory and kernel context the static memory. I didn't restore this swapping since it would have been unnatural to have all kernel contexts except 1 dynamic. The constructor for terminal context has bad layering for reasons related to the bug. It has to return static memory early before malloc() works. Callers also can't allocate memory until after the first constructor selects an emulator and tells upper layers the size of its context. After that, the cloning hack required the cloning code to allocate the memory, but for all other constructors it would be better for the terminal layer to allocate and deallocate the memory in all cases. Zero the memory when allocating terminal contexts dynamically.

Update for the KDB framework. Sanitize the alpha console code now that it's in the way even more. Basicly: remove all alpha specific console support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console initialization to be identical to all other platforms. In a nutshell: call cninit(). The platform specific code now only sets or clears RB_SERIAL and thus automaticly causes the right console to be selected. sio.c: o Replace the remote GDB hacks and use the GDB debug port interface instead. o Make debugging code conditional upon KDB instead of DDB. o Call kdb_alt_break() instead of db_alt_break(). o Call kdb_enter() instead of breakpoint(). o Remove the ugly compatibility of using the console as the debug port.

Fix missing switching of the terminal emulator when switching the terminal state for kernel console output. r56043 in 2000 added many complications to support dynamic selection of the terminal emulator using modules and the ioctl CONS_SETTERM. This was never completed. There are still no modules, but it is easy to restore the scterm and dumb emulators at compile time. Then boot-time configuration for the preferred one doesn't work right, but CONS_SETTERM almost works after fixing this bug. CONS_SETTERM only switches the emulator for the user state, leaving the kernel state(s) still using the boot-time emulator. The fix is especially important when switching from sc to scteken, since the scteken state has pointers in it. Rename kernel_console_ts to sc_kts.

Scattered calls to sc_cnputc() and sc_cngetc() were broken by turning the semi-reentrant inline context-switching code in these functions into the grabbing functions. cncheckc() calls for panic dumps are the main broken case. The grabbing functions have special behaviour (mainly screen switching in sc_cngrab()) which makes them unsuitable as replacements for the inline code.

static void sccnclose(sc_softc_t *sc, struct sc_cnstate *sp);
Start adding locking to sc_cngetc(). Restore an splx() lost in r228644. We aren't nearly ready to remove spl's. They give hints about missing locking. This lost one was misplaced. Dropping it early for convenience gave race windows for accesses to the fkey buffer. Giant locking accidentally fixed this for non-console cases. Put the spl's around the whole function. Since there are many returns that would need splx() just before them for a direct fix, split the function into a wrapper that does the spl's and a "locked" function that does the work. Return earlier when no keyboard is attached to match the ordering in a planned version. This breaks the dubious feature of returning keys from the fkey buffer after the keyboard has gone away. Losing the keys wouldn't matter, but we keep them too long now.

static int sc_cngetc_locked(struct sc_cnstate *sp);
Add some locking to sc_cngetc(). Keyboard input needs Giant locking, and that is not possible to do correctly here. Use mtx_trylock() and proceed unlocked as before if we can't acquire Giant (non-recursively), except in kdb mode don't even try to acquire Giant. Everything here is a hack, but it often works. Even if mtx_trylock() succeeds, this might be a LOR. Keyboard input also needs screen locking, to handle screen updates and switches. Add this, using the same simplistic screen locking as for sc_cnputc(). Giant must be acquired before the screen lock, and the screen lock must be dropped when calling the keyboard driver (else it would get a harmless LOR if it tries to acquire Giant). It was intended that sc cn open/close hide the locking calls, and they do for i/o functions functions except for this complication. Non-console keyboard input is still only Giant-locked, with screen locking in some called functions. This is correct for the keyboard parts only. When Giant cannot be acquired properly, atkbd and kbdmux tend to race and work (they assume that the caller acquired Giant properly and don't try to acquire it again or check that it has been acquired, and the races rarely matter), while ukbd tends to deadlock or panic (since it does the opposite, and has other usb threads to deadlock with). The keyboard (Giant) locking here does very little, but the screen locking completes screen locking for console mode except for not detecting or handling deadlock.

The log message for the previous commit didn't mention the most the important detail that sc_cngetc() now opens and closes the keyboard on every call again. This was moved from sc_cngetc() to scn_cngrab/ ungrab() in r228644, but the change wasn't quite complete. After fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens and closes should have no significant effect if done while grabbed. They fix unusual cases when cngetc() is called while not grabbed. This commit is the main fix for screen locking in sc_cnputc(): detect deadlock or likely-deadlock and handle it by buffering the output atomically and printing it later if the deadlock condition clears (and sc_cnputc() is called). The most common deadlock is when the screen lock is held by ourself. Then it would be safe to acquire the lock recursively if the console driver is calling printf() in a safe context, but we don't know when that is. It is not safe to ignore the lock even in kdb or panic mode. But ignore it in panic mode. The only other known case of deadlock is when another thread holds the lock but is running on a stopped CPU. Detect that case approximately by using trylock and retrying for 1000 usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches take slightly longer than that. Not retrying at all is good enough except for stress tests, and planned future versions will extend the timeout so that the stress tests work better. To see the behaviour when deadlock is detected, single step through sctty_outwakeup() (or sc_puts() to start with deadlock). Another (serial) console is needed to the buffered-only output, but the keyboard works in this context to continue or step out of the deadlocked region. The buffer is not large enough to hold all the output for this.

The log message for the previous commit didn't mention the most the important detail that sc_cngetc() now opens and closes the keyboard on every call again. This was moved from sc_cngetc() to scn_cngrab/ ungrab() in r228644, but the change wasn't quite complete. After fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens and closes should have no significant effect if done while grabbed. They fix unusual cases when cngetc() is called while not grabbed. This commit is the main fix for screen locking in sc_cnputc(): detect deadlock or likely-deadlock and handle it by buffering the output atomically and printing it later if the deadlock condition clears (and sc_cnputc() is called). The most common deadlock is when the screen lock is held by ourself. Then it would be safe to acquire the lock recursively if the console driver is calling printf() in a safe context, but we don't know when that is. It is not safe to ignore the lock even in kdb or panic mode. But ignore it in panic mode. The only other known case of deadlock is when another thread holds the lock but is running on a stopped CPU. Detect that case approximately by using trylock and retrying for 1000 usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches take slightly longer than that. Not retrying at all is good enough except for stress tests, and planned future versions will extend the timeout so that the stress tests work better. To see the behaviour when deadlock is detected, single step through sctty_outwakeup() (or sc_puts() to start with deadlock). Another (serial) console is needed to the buffered-only output, but the keyboard works in this context to continue or step out of the deadlocked region. The buffer is not large enough to hold all the output for this.

Reorganise a little to prepare for locking fixes: - in sccnopen(), open the keyboard before the screen. The keyboard currently requires Giant (although it must be spinlocked to work correctly as a console), so the previous order would be a LOR if it has any semblance of locking. - add a (currently dummy) state arg to scgetc().

Add some locking to sc_cngetc(). Keyboard input needs Giant locking, and that is not possible to do correctly here. Use mtx_trylock() and proceed unlocked as before if we can't acquire Giant (non-recursively), except in kdb mode don't even try to acquire Giant. Everything here is a hack, but it often works. Even if mtx_trylock() succeeds, this might be a LOR. Keyboard input also needs screen locking, to handle screen updates and switches. Add this, using the same simplistic screen locking as for sc_cnputc(). Giant must be acquired before the screen lock, and the screen lock must be dropped when calling the keyboard driver (else it would get a harmless LOR if it tries to acquire Giant). It was intended that sc cn open/close hide the locking calls, and they do for i/o functions functions except for this complication. Non-console keyboard input is still only Giant-locked, with screen locking in some called functions. This is correct for the keyboard parts only. When Giant cannot be acquired properly, atkbd and kbdmux tend to race and work (they assume that the caller acquired Giant properly and don't try to acquire it again or check that it has been acquired, and the races rarely matter), while ukbd tends to deadlock or panic (since it does the opposite, and has other usb threads to deadlock with). The keyboard (Giant) locking here does very little, but the screen locking completes screen locking for console mode except for not detecting or handling deadlock.

Add some locking to sc_cngetc(). Keyboard input needs Giant locking, and that is not possible to do correctly here. Use mtx_trylock() and proceed unlocked as before if we can't acquire Giant (non-recursively), except in kdb mode don't even try to acquire Giant. Everything here is a hack, but it often works. Even if mtx_trylock() succeeds, this might be a LOR. Keyboard input also needs screen locking, to handle screen updates and switches. Add this, using the same simplistic screen locking as for sc_cnputc(). Giant must be acquired before the screen lock, and the screen lock must be dropped when calling the keyboard driver (else it would get a harmless LOR if it tries to acquire Giant). It was intended that sc cn open/close hide the locking calls, and they do for i/o functions functions except for this complication. Non-console keyboard input is still only Giant-locked, with screen locking in some called functions. This is correct for the keyboard parts only. When Giant cannot be acquired properly, atkbd and kbdmux tend to race and work (they assume that the caller acquired Giant properly and don't try to acquire it again or check that it has been acquired, and the races rarely matter), while ukbd tends to deadlock or panic (since it does the opposite, and has other usb threads to deadlock with). The keyboard (Giant) locking here does very little, but the screen locking completes screen locking for console mode except for not detecting or handling deadlock.

atomic_add_int(&sc->grab_level, -1);
Restructure the grabbing functions into mere wrappers of new open and close functions. Scattered calls to sc_cnputc() and sc_cngetc() were broken by turning the semi-reentrant inline context-switching code in these functions into the grabbing functions. cncheckc() calls for panic dumps are the main broken case. The grabbing functions have special behaviour (mainly screen switching in sc_cngrab()) which makes them unsuitable as replacements for the inline code.

The log message for the previous commit didn't mention the most the important detail that sc_cngetc() now opens and closes the keyboard on every call again. This was moved from sc_cngetc() to scn_cngrab/ ungrab() in r228644, but the change wasn't quite complete. After fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens and closes should have no significant effect if done while grabbed. They fix unusual cases when cngetc() is called while not grabbed. This commit is the main fix for screen locking in sc_cnputc(): detect deadlock or likely-deadlock and handle it by buffering the output atomically and printing it later if the deadlock condition clears (and sc_cnputc() is called). The most common deadlock is when the screen lock is held by ourself. Then it would be safe to acquire the lock recursively if the console driver is calling printf() in a safe context, but we don't know when that is. It is not safe to ignore the lock even in kdb or panic mode. But ignore it in panic mode. The only other known case of deadlock is when another thread holds the lock but is running on a stopped CPU. Detect that case approximately by using trylock and retrying for 1000 usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches take slightly longer than that. Not retrying at all is good enough except for stress tests, and planned future versions will extend the timeout so that the stress tests work better. To see the behaviour when deadlock is detected, single step through sctty_outwakeup() (or sc_puts() to start with deadlock). Another (serial) console is needed to the buffered-only output, but the keyboard works in this context to continue or step out of the deadlocked region. The buffer is not large enough to hold all the output for this.

scr_stat *scp = sc_console;
Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Less-quick fix for locking fixes in r172250. r172250 added a second syscons spinlock for the output routine alone. It is better to extend the coverage of the first syscons spinlock added in r162285. 2 locks might work with complicated juggling, but no juggling was done. What the 2 locks actually did was to cover some of the missing locking in each other and deadlock less often against each other than a single lock with larger coverage would against itself. Races are preferable to deadlocks here, but 2 locks are still worse since they are harder to understand and fix. Prefer deadlocks to races and merge the second lock into the first one. Extend the scope of the spinlocking to all of sc_cnputc() instead of just the sc_puts() part. This further prefers deadlocks to races. Extend the kdb_active hack from sc_puts() internals for the second lock to all spinlocking. This reduces deadlocks much more than the other changes increases them. The s/p,10* test in ddb gets much further now. Hide this detail in the SC_VIDEO_LOCK() macro. Add namespace pollution in 1 nested #include and reduce namespace pollution in other nested #includes to pay for this. Move the first lock higher in the witness order. The second lock was unnaturally low and the first lock was unnaturally high. The second lock had to be above "sleepq chain" and/or "callout" to avoid spurious LORs for visual bells in sc_puts(). Other console driver locks are already even higher (but not adjacent like they should be) except when they are missing from the table. Audio bells also benefit from the syscons lock being high so that audio mutexes have chance of being lower. Otherwise, console drviver locks should be as low as possible. Non-spurious LORs now occur if the bell code calls printf() or is interrupted (perhaps by an NMI) and the interrupt handler calls printf(). Previous commits turned off many bells in console i/o but missed ones done by the teken layer.

Implement ec_putc() (emergency kernel [syscons] console putc()) and use it in emergency in sc_cnputc(). Locking fixes in sc_cnputc() previously turned off normal output in near-deadlock conditions and added deferred output which might never be completed. Emergency output goes to the frame buffer using sufficiently atomic non-blocking writes if the console is in text mode (in graphics mode, nothing is done, modulo races setting the graphics mode bit). Screen updates overwrite the emergency output if the emergency condition clears enough to reach them. ec_putc() also works for "early" console output in normal x86 text mode as soon as this mode is initialized (if ever). This uses a hard-coded x86 frame buffer address before cninit() and a hopefully MI address after cninit(). But non-x86 is more likely to not support text mode, when ec_putc() will be null. ec_putc() has no dependencies of syscons before cninit(), and only has them later to track syscons' mode changes.

Implement ec_putc() (emergency kernel [syscons] console putc()) and use it in emergency in sc_cnputc(). Locking fixes in sc_cnputc() previously turned off normal output in near-deadlock conditions and added deferred output which might never be completed. Emergency output goes to the frame buffer using sufficiently atomic non-blocking writes if the console is in text mode (in graphics mode, nothing is done, modulo races setting the graphics mode bit). Screen updates overwrite the emergency output if the emergency condition clears enough to reach them. ec_putc() also works for "early" console output in normal x86 text mode as soon as this mode is initialized (if ever). This uses a hard-coded x86 frame buffer address before cninit() and a hopefully MI address after cninit(). But non-x86 is more likely to not support text mode, when ec_putc() will be null. ec_putc() has no dependencies of syscons before cninit(), and only has them later to track syscons' mode changes.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Disable processing of output data after disabling scroll lock by force. The syscons code disabled scroll lock inside sc_cnputs() if it's going to print a system message. The code currently wants to process any TTY output data as well, but we cannot do this, because the TTY lock is a sleep mutex, while cnputs() picks up a spin mutex. Disable the code for now. It solves a panic when a console message is printed while scroll lock is enabled. One solution would be to initialize a task structure here. Reported by: Paul B. Mahol <onemda gmail com>

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

The log message for the previous commit didn't mention the most the important detail that sc_cngetc() now opens and closes the keyboard on every call again. This was moved from sc_cngetc() to scn_cngrab/ ungrab() in r228644, but the change wasn't quite complete. After fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens and closes should have no significant effect if done while grabbed. They fix unusual cases when cngetc() is called while not grabbed. This commit is the main fix for screen locking in sc_cnputc(): detect deadlock or likely-deadlock and handle it by buffering the output atomically and printing it later if the deadlock condition clears (and sc_cnputc() is called). The most common deadlock is when the screen lock is held by ourself. Then it would be safe to acquire the lock recursively if the console driver is calling printf() in a safe context, but we don't know when that is. It is not safe to ignore the lock even in kdb or panic mode. But ignore it in panic mode. The only other known case of deadlock is when another thread holds the lock but is running on a stopped CPU. Detect that case approximately by using trylock and retrying for 1000 usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches take slightly longer than that. Not retrying at all is good enough except for stress tests, and planned future versions will extend the timeout so that the stress tests work better. To see the behaviour when deadlock is detected, single step through sctty_outwakeup() (or sc_puts() to start with deadlock). Another (serial) console is needed to the buffered-only output, but the keyboard works in this context to continue or step out of the deadlocked region. The buffer is not large enough to hold all the output for this.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Fix missing switching of the terminal emulator when switching the terminal state for kernel console output. r56043 in 2000 added many complications to support dynamic selection of the terminal emulator using modules and the ioctl CONS_SETTERM. This was never completed. There are still no modules, but it is easy to restore the scterm and dumb emulators at compile time. Then boot-time configuration for the preferred one doesn't work right, but CONS_SETTERM almost works after fixing this bug. CONS_SETTERM only switches the emulator for the user state, leaving the kernel state(s) still using the boot-time emulator. The fix is especially important when switching from sc to scteken, since the scteken state has pointers in it. Rename kernel_console_ts to sc_kts.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

The switch to kernel terminal context needs to update more than the cursor position. Especially the screen size, and potentially everything except the input state and attributes. Do this by changing the cursor position setting method to a general syncing method. Use proper constructors instead of copying to create kernel terminal contexts. We really want clones and not new instances, but there is no method for cloning and there is nothing in the active instance that needs to be cloned exactly. Add proper destructors for kernel terminal contexts. I doubt that the destructor code has every been reached, but if it was then it leaked the memory of the clones. Remove freeing of statically allocated memory for the non-kernel terminal context for the same terminal as the kernel. This is in the nearly unreachable code. This used to not happen because delicate context swapping made the user context use the dynamic memory and kernel context the static memory. I didn't restore this swapping since it would have been unnatural to have all kernel contexts except 1 dynamic. The constructor for terminal context has bad layering for reasons related to the bug. It has to return static memory early before malloc() works. Callers also can't allocate memory until after the first constructor selects an emulator and tells upper layers the size of its context. After that, the cloning hack required the cloning code to allocate the memory, but for all other constructors it would be better for the terminal layer to allocate and deallocate the memory in all cases. Zero the memory when allocating terminal contexts dynamically.

The log message for the previous commit didn't mention the most the important detail that sc_cngetc() now opens and closes the keyboard on every call again. This was moved from sc_cngetc() to scn_cngrab/ ungrab() in r228644, but the change wasn't quite complete. After fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens and closes should have no significant effect if done while grabbed. They fix unusual cases when cngetc() is called while not grabbed. This commit is the main fix for screen locking in sc_cnputc(): detect deadlock or likely-deadlock and handle it by buffering the output atomically and printing it later if the deadlock condition clears (and sc_cnputc() is called). The most common deadlock is when the screen lock is held by ourself. Then it would be safe to acquire the lock recursively if the console driver is calling printf() in a safe context, but we don't know when that is. It is not safe to ignore the lock even in kdb or panic mode. But ignore it in panic mode. The only other known case of deadlock is when another thread holds the lock but is running on a stopped CPU. Detect that case approximately by using trylock and retrying for 1000 usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches take slightly longer than that. Not retrying at all is good enough except for stress tests, and planned future versions will extend the timeout so that the stress tests work better. To see the behaviour when deadlock is detected, single step through sctty_outwakeup() (or sc_puts() to start with deadlock). Another (serial) console is needed to the buffered-only output, but the keyboard works in this context to continue or step out of the deadlocked region. The buffer is not large enough to hold all the output for this.

The first stage of console driver reorganization: activate new keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Add screen locking calls to sc cn grab and ungrab. The locking functions just use the same mutex locking as sc cn putc so they have the same defects. The locking calls to acquire the lock are actually in sc cn open and close. Ungrab has to unlock, although this opens a race window. Change the direct mutex lock calls in sc cn putc to the new locking functions via the open and close functions. Putc also has to unlock, but doesn't keep the screen open like grab. Screen open and close reduce to locking, except screen open for grab also attempts to switch the screen. Keyboard locking is more difficult and still null, even when keyboard input calls screen functions, except some of the functions have locks too deep to work right. This organization gives a single place to fix some of the locking.

Dropping it early for convenience gave race windows for accesses to the fkey buffer. Giant locking accidentally fixed this for non-console cases. Put the spl's around the whole function. Since there are many returns that would need splx() just before them for a direct fix, split the function into a wrapper that does the spl's and a "locked" function that does the work.

Add some locking to sc_cngetc(). Keyboard input needs Giant locking, and that is not possible to do correctly here.

Even if mtx_trylock() succeeds, this might be a LOR. Keyboard input also needs screen locking, to handle screen updates and switches. Add this, using the same simplistic screen locking as for sc_cnputc(). Giant must be acquired before the screen lock, and the screen lock must be dropped when calling the keyboard driver (else it would get a harmless LOR if it tries to acquire Giant). It was intended that sc cn open/close hide the locking calls, and they do for i/o functions functions except for this complication. Non-console keyboard input is still only Giant-locked, with screen locking in some called functions. This is correct for the keyboard parts only. When Giant cannot be acquired properly, atkbd and kbdmux tend to race and work (they assume that the caller acquired Giant properly and don't try to acquire it again or check that it has been acquired, and the races rarely matter), while ukbd tends to deadlock or panic (since it does the opposite, and has other usb threads to deadlock with).

Add some locking to sc_cngetc(). Keyboard input needs Giant locking, and that is not possible to do correctly here. Use mtx_trylock() and proceed unlocked as before if we can't acquire Giant (non-recursively), except in kdb mode don't even try to acquire Giant. Everything here is a hack, but it often works. Even if mtx_trylock() succeeds, this might be a LOR. Keyboard input also needs screen locking, to handle screen updates and switches. Add this, using the same simplistic screen locking as for sc_cnputc(). Giant must be acquired before the screen lock, and the screen lock must be dropped when calling the keyboard driver (else it would get a harmless LOR if it tries to acquire Giant). It was intended that sc cn open/close hide the locking calls, and they do for i/o functions functions except for this complication. Non-console keyboard input is still only Giant-locked, with screen locking in some called functions. This is correct for the keyboard parts only. When Giant cannot be acquired properly, atkbd and kbdmux tend to race and work (they assume that the caller acquired Giant properly and don't try to acquire it again or check that it has been acquired, and the races rarely matter), while ukbd tends to deadlock or panic (since it does the opposite, and has other usb threads to deadlock with).

PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized.

Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen.

This option replaces the existing STD8X16FONT option, which loads 16-line font data only. - The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c. - The video driver provides a set of ioctl commands to manipulate the frame buffer. - New kernel configuration option: VGA_WIDTH90 Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are mot always supported by the video card. PR: i386/7510 Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx. - The header file machine/console.h is reorganized; its contents is now split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h (another new file). machine/console.h is still maintained for compatibility reasons. - Kernel console selection/installation routines are fixed and slightly rebumped so that it should now be possible to switch between the interanl kernel console (sc or vt) and a remote kernel console (sio) again, as it was in 2.x, 3.0 and 3.1. - Screen savers and splash screen decoders Because of the header file reorganization described above, screen savers and splash screen decoders are slightly modified.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source.

The log message for the previous commit didn't mention the most the important detail that sc_cngetc() now opens and closes the keyboard on every call again. This was moved from sc_cngetc() to scn_cngrab/ ungrab() in r228644, but the change wasn't quite complete. After fixes for nesting in kbdd_poll() in ukbd and kbdmux, these opens and closes should have no significant effect if done while grabbed. They fix unusual cases when cngetc() is called while not grabbed. This commit is the main fix for screen locking in sc_cnputc(): detect deadlock or likely-deadlock and handle it by buffering the output atomically and printing it later if the deadlock condition clears (and sc_cnputc() is called). The most common deadlock is when the screen lock is held by ourself. Then it would be safe to acquire the lock recursively if the console driver is calling printf() in a safe context, but we don't know when that is. It is not safe to ignore the lock even in kdb or panic mode. But ignore it in panic mode. The only other known case of deadlock is when another thread holds the lock but is running on a stopped CPU. Detect that case approximately by using trylock and retrying for 1000 usec. On a 4 GHz CPU, 100 usec is almost long enough -- screen switches take slightly longer than that. Not retrying at all is good enough except for stress tests, and planned future versions will extend the timeout so that the stress tests work better. To see the behaviour when deadlock is detected, single step through sctty_outwakeup() (or sc_puts() to start with deadlock). Another (serial) console is needed to the buffered-only output, but the keyboard works in this context to continue or step out of the deadlocked region. The buffer is not large enough to hold all the output for this.

Remove explicit calls to keyboard methods with their respective variants implemented with macros. This patch improves code readability. Reasoning behind kbdd_* is a "keyboard discipline". List of macros is supposed to be complete--all methods of keyboard_switch should have their respective macros from now on. Functionally, this code should be no-op. My intention is to leave current behaviour of code as is. Glanced at by: rwatson Reviewed by: emax, marcel Approved by: cognet

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV.

PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized.

The first stage of console driver reorganization: activate new keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Change all uses of 'debugger' to kdb_active and remove this variable. This restores avoidance of doing dangerous things like calling wakeup() and callouts while in ddb. Initialization of 'debugger' was broken by removing the cndbctl() console method that was used mainly in this driver to initialize 'debugger' and switch to the console screen on entry to ddb. The screen switch was restored using the cngrab() method, but cngrab() is more general so it should not initialize 'debugger' and never did. 'debugger' was just an over-engineered alias for kdb_active anyway. It existed because kdb_active (when it was named ddb_active) was considered as a private kdb variable, and there are ordering problems initializing the variables atomically with the state that they represent, but an extra variable and method to set it increased these problems. The bug caused LORs, but WITNESS is normally misconfigured with WITNESS_SKIPSIN so it doesn't check the spinlocks used by wakeup() and callouts.

1. Reorganized screen saver related code so that both the LKM screen saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.

o Restore removed hardware cursor support and make it _default_ case, software cursor now optional case. Driver must provide raw things (what hardware do for us, exactly) as default case, all driver features must be _optional_. Modern VGAs have internal configuration utilities to set cursor shape/blinking which stored into cards ROM, and syscons nuke out such features completely by forcing software cursor. Moreover, software cursor is hard to distinguish on standouted (or near standouted) fields and tends to disappearse from the screen. Set "flags 0x4" to enable software cursor now. o Cleanup screen savers. o Don't draw cursor if saver or blinker is active. o Duplicated code moved to functons. o Add more checks for blinker in progress, character lost otherwise when blinker restore old contents. o Reduce blinking counter to 3, too slow in old variant. o Fix timeout code in scrn_timer(), old variant can reenter iself, if action takes too long time. o Disable visual bell for scroll lock mode, saved screen becomes overwritted otherwise.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

/* should we stop the screen saver? */
Change all uses of 'debugger' to kdb_active and remove this variable. This restores avoidance of doing dangerous things like calling wakeup() and callouts while in ddb. Initialization of 'debugger' was broken by removing the cndbctl() console method that was used mainly in this driver to initialize 'debugger' and switch to the console screen on entry to ddb. The screen switch was restored using the cngrab() method, but cngrab() is more general so it should not initialize 'debugger' and never did. 'debugger' was just an over-engineered alias for kdb_active anyway. It existed because kdb_active (when it was named ddb_active) was considered as a private kdb variable, and there are ordering problems initializing the variables atomically with the state that they represent, but an extra variable and method to set it increased these problems. The bug caused LORs, but WITNESS is normally misconfigured with WITNESS_SKIPSIN so it doesn't check the spinlocks used by wakeup() and callouts.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2.

Next syscons update (given up on numbering :) Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

Introduce a spinlock for synchronizing access to the video output hardware in syscons. This replaces a simple access semaphore that was assumed to be protected by Giant but often was not. If two threads that were otherwise SMP-safe called printf at the same time, there was a high likelyhood that the semaphore would get corrupted and result in a permanently frozen video console. This is similar to what is already done in the serial console drivers.

Add support for VESA mode 0x102 (800x600x4) in syscons. You can activate this using option "-b" to the boot blocks. It is smartest to compile a font into your kernel (See LINT), but not mandatory, but apart from the cursor you will see nothing on the screen until you load a font. This mode allows XF86_VGA16 to run in 800x600 mode on otherwise unsupported graphics hardware. A number of buglets in the cursor handling in syscons may become visible this way.

This is similar to what is already done in the serial console drivers.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Add support for VESA mode 0x102 (800x600x4) in syscons. You can activate this using option "-b" to the boot blocks. It is smartest to compile a font into your kernel (See LINT), but not mandatory, but apart from the cursor you will see nothing on the screen until you load a font. This mode allows XF86_VGA16 to run in 800x600 mode on otherwise unsupported graphics hardware. A number of buglets in the cursor handling in syscons may become visible this way.

add_scrn_saver(void (*this_saver)(sc_softc_t *, int))
Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA.

1. Reorganized screen saver related code so that both the LKM screen saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

The first stage of console driver reorganization: activate new keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode. The 80x25 text will be displayed on the 800x600 screen. Useful for some laptop computers. vidcontrol accepts the new `-i <info>' option, where <info> must be either `adapter' or `mode'. When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter. When the `-i mode' option is specified, vidcontrol will list video modes which are actually supported by the video adapter. Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source.

Change all uses of 'debugger' to kdb_active and remove this variable. This restores avoidance of doing dangerous things like calling wakeup() and callouts while in ddb. Initialization of 'debugger' was broken by removing the cndbctl() console method that was used mainly in this driver to initialize 'debugger' and switch to the console screen on entry to ddb. The screen switch was restored using the cngrab() method, but cngrab() is more general so it should not initialize 'debugger' and never did. 'debugger' was just an over-engineered alias for kdb_active anyway.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Introduce a spinlock for synchronizing access to the video output hardware in syscons. This replaces a simple access semaphore that was assumed to be protected by Giant but often was not. If two threads that were otherwise SMP-safe called printf at the same time, there was a high likelyhood that the semaphore would get corrupted and result in a permanently frozen video console. This is similar to what is already done in the serial console drivers.

Sometimes the vty switching has to be delayed; the vty to be switched to is saved in sc->delayed_next_scr and the actual switch is performed later. It was possible to get into the endless loop when attempting to switch to a closed vty (which is not allowed and beep-alerted when attempted) and when the visual beep was in effect. This caused sc->delayed_next_scr to never be reset and endless attempts to switch to a closed vty and endless visual beeping.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Change all uses of 'debugger' to kdb_active and remove this variable. This restores avoidance of doing dangerous things like calling wakeup() and callouts while in ddb. Initialization of 'debugger' was broken by removing the cndbctl() console method that was used mainly in this driver to initialize 'debugger' and switch to the console screen on entry to ddb. The screen switch was restored using the cngrab() method, but cngrab() is more general so it should not initialize 'debugger' and never did. 'debugger' was just an over-engineered alias for kdb_active anyway. It existed because kdb_active (when it was named ddb_active) was considered as a private kdb variable, and there are ordering problems initializing the variables atomically with the state that they represent, but an extra variable and method to set it increased these problems. The bug caused LORs, but WITNESS is normally misconfigured with WITNESS_SKIPSIN so it doesn't check the spinlocks used by wakeup() and callouts.

Change all uses of 'debugger' to kdb_active and remove this variable. This restores avoidance of doing dangerous things like calling wakeup() and callouts while in ddb. Initialization of 'debugger' was broken by removing the cndbctl() console method that was used mainly in this driver to initialize 'debugger' and switch to the console screen on entry to ddb. The screen switch was restored using the cngrab() method, but cngrab() is more general so it should not initialize 'debugger' and never did. 'debugger' was just an over-engineered alias for kdb_active anyway. It existed because kdb_active (when it was named ddb_active) was considered as a private kdb variable, and there are ordering problems initializing the variables atomically with the state that they represent, but an extra variable and method to set it increased these problems. The bug caused LORs, but WITNESS is normally misconfigured with WITNESS_SKIPSIN so it doesn't check the spinlocks used by wakeup() and callouts.

The first stage of console driver reorganization: activate new keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

/* save the current state of video and keyboard */
This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

/* set up the keyboard for the new screen */
Flesh out the state and flags args to sccnopen(). Set state flags to indicate (potentially partial) success of the open. Use these to decide what to close in sccnclose(). Only grab/ungrab use open/close so far. Add a per-sc variable to count successful keyboard opens and use this instead of the grab count to decide if the keyboad state has been switched. Start fixing the locking by using atomic ops for the most important counter -- the grab level one. Other racy counting will eventually be fixed by normal mutex or kdb locking in most cases. Use a 2-entry per-sc stack of states for grabbing. 2 is just enough to debug grabbing, e.g., for gets(). gets() grabs once and might not be able to do a full (or any) state switch. ddb grabs again and has a better chance of doing a full state switch and needs a place to stack the previous state. For more than 3 levels, grabbing just changes the count. Console drivers should try to switch on every i/o in case lower levels of nesting failed to switch but the current level succeeds, but then the switch (back) must be completed on every i/o and this flaps the state unless the switch is null. The main point of grabbing is to make it null quite often. Syscons grabbing also does a carefully chosen screen focus that is not done on every i/o. Add a large comment about grabbing. Restore some small lost comments.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

1. Reorganized screen saver related code so that both the LKM screen saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.

Screen saver related fixes. 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde

Less-quick fix for locking fixes in r172250. r172250 added a second syscons spinlock for the output routine alone. It is better to extend the coverage of the first syscons spinlock added in r162285. 2 locks might work with complicated juggling, but no juggling was done. What the 2 locks actually did was to cover some of the missing locking in each other and deadlock less often against each other than a single lock with larger coverage would against itself. Races are preferable to deadlocks here, but 2 locks are still worse since they are harder to understand and fix. Prefer deadlocks to races and merge the second lock into the first one. Extend the scope of the spinlocking to all of sc_cnputc() instead of just the sc_puts() part. This further prefers deadlocks to races. Extend the kdb_active hack from sc_puts() internals for the second lock to all spinlocking. This reduces deadlocks much more than the other changes increases them. The s/p,10* test in ddb gets much further now. Hide this detail in the SC_VIDEO_LOCK() macro. Add namespace pollution in 1 nested #include and reduce namespace pollution in other nested #includes to pay for this. Move the first lock higher in the witness order. The second lock was unnaturally low and the first lock was unnaturally high. The second lock had to be above "sleepq chain" and/or "callout" to avoid spurious LORs for visual bells in sc_puts(). Other console driver locks are already even higher (but not adjacent like they should be) except when they are missing from the table. Audio bells also benefit from the syscons lock being high so that audio mutexes have chance of being lower. Otherwise, console drviver locks should be as low as possible. Non-spurious LORs now occur if the bell code calls printf() or is interrupted (perhaps by an NMI) and the interrupt handler calls printf(). Previous commits turned off many bells in console i/o but missed ones done by the teken layer.

if (scp->tsw)
Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Introduce a spinlock for synchronizing access to the video output hardware in syscons. This replaces a simple access semaphore that was assumed to be protected by Giant but often was not. If two threads that were otherwise SMP-safe called printf at the same time, there was a high likelyhood that the semaphore would get corrupted and result in a permanently frozen video console. This is similar to what is already done in the serial console drivers.

Support setting the colors of cursors for the VGA renderer. Advertise this by changing the defaults to mostly red. If you don't like this, change them (almost) back using: vidcontrol -c charcolors,base=7,height=0 vidcontrol -c mousecolors,base=0[,height=15] The (graphics mode only) mouse cursor colors were hard-coded to a black border and lightwhite interior. Black for the border is the worst possible default, since it is the same as the default black background and not good for any dark background. Reversing this gives the better default of X Windows. Coloring everything works better still. Now the coloring defaults to a lightwhite border and red interior. Coloring for the character cursor is more complicated and mode dependent. The new coloring doesn't apply for hardware cursors. For non-block cursors, it only applies in graphics mode. In text mode, the cursor color was usually a hard-coded (dull)white for the background only, unless the foreground was white when it was a hard-coded black for the background only, unless the foreground was white and the background was black it was reverse video. In graphics mode, it was always reverse video for the block cursor. Reverse video is worse, especially over cutmarking regions, since cutmarking still uses simple reverse video (nothing better is possible in text mode) and double reverse video for the cursor gives normal video. Now, graphics mode uses the same algorithm as the best case for text mode in all cases for graphics mode. The hard-coded sequence { white, black, } for the background is now { red, white, blue, } where the first 2 colors can be configured. The blue color at the end is a sentinel which prevents reverse video being used in most cases but breaks the compatibility setting for white on black and black on white characters. This will be fixed later. The compatibility setting is most needed for mono modes. The previous commit to syscons.c changed sc_cnterm() to be more careful. It followed null pointers in some cases. But sc_cnterm() has been unreachable for 15+ years since changes for multiple consoles turned off calls to the the cnterm destructor for all console drivers. Before them, it was only called at boot time. So no driver with an attached console has ever been unloadable and not even the non-console destructors have been tested much.

Fix setting of defaults for the text cursor. There was already a per-vty defaults field, but it was useless since it was only initialized when propagating the global settings and thus no different from the current global settings and not per-vty. The global defaults field was also invariant after boot time, but not quite so useless. Fix this by adding a second selection bit the the control flags of the relevant ioctl(). vidcontrol doesn't support this yet. Setting either default propagates the change to the current setting for the same level and then to all lower levels. Improve the 3-way escape sequence used by termcap to control the cursor. The "normal" (ve) case has always used reset, so the user could set it to anything, but since the reset is to a global value this is not very useful, especially since the "very visible" (vs) case doesn't reset but inconsistently forces to a blinking block. Change vs to first reset and then XOR the blinking bit so that it is predictably different from ve.

Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode. The 80x25 text will be displayed on the 800x600 screen. Useful for some laptop computers. vidcontrol accepts the new `-i <info>' option, where <info> must be either `adapter' or `mode'. When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter. When the `-i mode' option is specified, vidcontrol will list video modes which are actually supported by the video adapter. Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Make comp_vgaregs() less strict about VGA register values when checking the BIOS video mode paramter table. Now syscons uses the parameter table even if some bits in the table are different from the current VGA register settings. Even if comp_vgaregs() finds that the BIOS video parameter table looks totally unfamiliar to it, syscons allows the user to change the current video mode to some modes which are based on the VGA 80x25 mode. They are VGA 80x30, VGA 80x50, VGA 80x60. In this case the user will be warned, during boot, that video mode switching is only paritally supported on his machine. PR: bin/4477

Add VESA support to syscons. Kazu writes: The VESA support code requires vm86 support. Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode. The 80x25 text will be displayed on the 800x600 screen. Useful for some laptop computers. vidcontrol accepts the new `-i <info>' option, where <info> must be either `adapter' or `mode'. When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter. When the `-i mode' option is specified, vidcontrol will list video modes which are actually supported by the video adapter. Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

Fix setting of defaults for the text cursor. There was already a per-vty defaults field, but it was useless since it was only initialized when propagating the global settings and thus no different from the current global settings and not per-vty. The global defaults field was also invariant after boot time, but not quite so useless. Fix this by adding a second selection bit the the control flags of the relevant ioctl(). vidcontrol doesn't support this yet. Setting either default propagates the change to the current setting for the same level and then to all lower levels. Improve the 3-way escape sequence used by termcap to control the cursor. The "normal" (ve) case has always used reset, so the user could set it to anything, but since the reset is to a global value this is not very useful, especially since the "very visible" (vs) case doesn't reset but inconsistently forces to a blinking block. Change vs to first reset and then XOR the blinking bit so that it is predictably different from ve.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Colorize syscons kernel console output according to a table indexed by the CPU number. This was originally for debugging near-deadlock conditions where multiple CPUs either deadlock or scramble each other's output trying to report the problem, but I found it interesting and sometimes useful for ordinary kernel messages. Ordinary kernel messages shouldn't be interleaved, but if they are then the colorization makes them readable even if the interleaving is for every character (provided the CPU printing each message doesn't change). The default colors are 8-15 starting at 15 (bright white on black) for CPU 0 and repeating every 8 CPUs. This works best with 8 CPUs. Non-bright colors and nonzero background colors need special configuration to avoid unreadable and ugly combinations so are not configured by default. The next bright color after 15 is 8 (bright black = dark gray) is not very readable but is the only other color used with 2 CPUs. After that the next bright color is 9 (bright blue) which is not much brighter than bright black, but is used with 3+ CPUs. Other bright colors are brighter. Colorization is configured by default so that it gets tested. It can only be turned off by configuring SC_KERNEL_CONS_ATTR to anything other than FG_WHITE. After booting, all colors can be changed using the syscons.kattr sysctl. This is a SYSCTL_OPAQUE, and no utility is provided to change it (sysctl only displays it). The default colors work in all VGA modes that I could test. In 2-color graphics modes, all 8 bright colors are displayed as bright white, so the colorization has no effect, but anything with a nonzero background gives white on white unless the foreground is zero. I don't have an mono or VGA grayscale hardware to test on. Support for mono mode seems to have never worked right in syscons (I think bright white gives white underline with either bold or bright), but VGA grayscale should work better than 2-color graphics.

After booting, all colors can be changed using the syscons.kattr sysctl. This is a SYSCTL_OPAQUE, and no utility is provided to change it (sysctl only displays it). The default colors work in all VGA modes that I could test. In 2-color graphics modes, all 8 bright colors are displayed as bright white, so the colorization has no effect, but anything with a nonzero background gives white on white unless the foreground is zero. I don't have an mono or VGA grayscale hardware to test on. Support for mono mode seems to have never worked right in syscons (I think bright white gives white underline with either bold or bright), but VGA grayscale should work better than 2-color graphics.

Less-quick fix for locking fixes in r172250. r172250 added a second syscons spinlock for the output routine alone. It is better to extend the coverage of the first syscons spinlock added in r162285. 2 locks might work with complicated juggling, but no juggling was done. What the 2 locks actually did was to cover some of the missing locking in each other and deadlock less often against each other than a single lock with larger coverage would against itself. Races are preferable to deadlocks here, but 2 locks are still worse since they are harder to understand and fix. Prefer deadlocks to races and merge the second lock into the first one. Extend the scope of the spinlocking to all of sc_cnputc() instead of just the sc_puts() part. This further prefers deadlocks to races. Extend the kdb_active hack from sc_puts() internals for the second lock to all spinlocking. This reduces deadlocks much more than the other changes increases them. The s/p,10* test in ddb gets much further now. Hide this detail in the SC_VIDEO_LOCK() macro. Add namespace pollution in 1 nested #include and reduce namespace pollution in other nested #includes to pay for this. Move the first lock higher in the witness order. The second lock was unnaturally low and the first lock was unnaturally high. The second lock had to be above "sleepq chain" and/or "callout" to avoid spurious LORs for visual bells in sc_puts(). Other console driver locks are already even higher (but not adjacent like they should be) except when they are missing from the table. Audio bells also benefit from the syscons lock being high so that audio mutexes have chance of being lower. Otherwise, console drviver locks should be as low as possible. Non-spurious LORs now occur if the bell code calls printf() or is interrupted (perhaps by an NMI) and the interrupt handler calls printf(). Previous commits turned off many bells in console i/o but missed ones done by the teken layer.

Introduce a spinlock for synchronizing access to the video output hardware in syscons. This replaces a simple access semaphore that was assumed to be protected by Giant but often was not. If two threads that were otherwise SMP-safe called printf at the same time, there was a high likelyhood that the semaphore would get corrupted and result in a permanently frozen video console. This is similar to what is already done in the serial console drivers.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Turn consolectl into a simple device node, not a TTY. Apart from the 16 virtual terminals, Syscons allocates two device nodes that should not really be TTYs, even though they are. One of them is consolectl. In RELENG_7 and before, these device nodes are used in single user mode. After I simplified input path, we only use this device node to call ioctl() on (moused, Xorg, vidcontrol). When you call ioctl() on consolectl, it will behave the same as being called on the first window.

Add a scteken_set_cursor() (sc to teken) method and use it to fix some cases of initialization and resetting of the teken cursor position. (This bad name is consistent with others, but it is too easy to confuse with scteken_cursor() which goes in the opposite direction.) The following cases were broken: - for booting without a syscons console, the teken and sc positions for ttyv0 were (0, 0), but are supposed to be somewhere in the middle of the screen (after carefully preserved BIOS and loader messages) (at least if there is no mode switch that loses the messages). - after mode switches, the screen is cleared and the cursor is supposed to be moved to (0, 0), but it was only moved there for sc. The following case was hacked to work: - for booting with a syscons console, it was arranged that scteken_init() for the console could see a nonzero cursor position and adjust, although this broke the sc seeing it in the non-console case above.

The switch to kernel terminal context needs to update more than the cursor position. Especially the screen size, and potentially everything except the input state and attributes. Do this by changing the cursor position setting method to a general syncing method. Use proper constructors instead of copying to create kernel terminal contexts. We really want clones and not new instances, but there is no method for cloning and there is nothing in the active instance that needs to be cloned exactly. Add proper destructors for kernel terminal contexts. I doubt that the destructor code has every been reached, but if it was then it leaked the memory of the clones. Remove freeing of statically allocated memory for the non-kernel terminal context for the same terminal as the kernel. This is in the nearly unreachable code. This used to not happen because delicate context swapping made the user context use the dynamic memory and kernel context the static memory. I didn't restore this swapping since it would have been unnatural to have all kernel contexts except 1 dynamic. The constructor for terminal context has bad layering for reasons related to the bug. It has to return static memory early before malloc() works. Callers also can't allocate memory until after the first constructor selects an emulator and tells upper layers the size of its context. After that, the cloning hack required the cloning code to allocate the memory, but for all other constructors it would be better for the terminal layer to allocate and deallocate the memory in all cases. Zero the memory when allocating terminal contexts dynamically.

Use better hard-coded defaults for the cursor shape, and remove nearby redundant initializations. Hard-code base = 0, height = (approx. 1/8 of the boot-time font height) in all cases, and remove the BIOS/MD support for setting these values. This asks for an underline cursor sized for the boot-time font instead of various less hard-coded but worse values. I used that think that the x86 BIOS always gave the same values as the above hard-coding, but on 1 of my systems it gives the wrong value of base = 1. The remaining BIOS fields are shift_state and bell_pitch. These are now consistently not explicitly reinitialized to 0. All sc_get_bios_value() functions except x86's are now empty, and the only useful thing that x86 returns is shift_state. This really belongs in atkbdc, but heavier use of the BIOS to read the more useful typematic rate has been removed there. fb still makes much heavier use of the BIOS.

Support setting the colors of cursors for the VGA renderer. Advertise this by changing the defaults to mostly red. If you don't like this, change them (almost) back using: vidcontrol -c charcolors,base=7,height=0 vidcontrol -c mousecolors,base=0[,height=15] The (graphics mode only) mouse cursor colors were hard-coded to a black border and lightwhite interior. Black for the border is the worst possible default, since it is the same as the default black background and not good for any dark background. Reversing this gives the better default of X Windows. Coloring everything works better still. Now the coloring defaults to a lightwhite border and red interior. Coloring for the character cursor is more complicated and mode dependent. The new coloring doesn't apply for hardware cursors. For non-block cursors, it only applies in graphics mode. In text mode, the cursor color was usually a hard-coded (dull)white for the background only, unless the foreground was white when it was a hard-coded black for the background only, unless the foreground was white and the background was black it was reverse video. In graphics mode, it was always reverse video for the block cursor. Reverse video is worse, especially over cutmarking regions, since cutmarking still uses simple reverse video (nothing better is possible in text mode) and double reverse video for the cursor gives normal video. Now, graphics mode uses the same algorithm as the best case for text mode in all cases for graphics mode. The hard-coded sequence { white, black, } for the background is now { red, white, blue, } where the first 2 colors can be configured. The blue color at the end is a sentinel which prevents reverse video being used in most cases but breaks the compatibility setting for white on black and black on white characters. This will be fixed later. The compatibility setting is most needed for mono modes. The previous commit to syscons.c changed sc_cnterm() to be more careful. It followed null pointers in some cases. But sc_cnterm() has been unreachable for 15+ years since changes for multiple consoles turned off calls to the the cnterm destructor for all console drivers. Before them, it was only called at boot time. So no driver with an attached console has ever been unloadable and not even the non-console destructors have been tested much.

Rename curr_curs_attr to base_curr_attr. The actual current cursor attribute field is curs_attr. The base field holds user data translated in a reversible way and is needed because current field holds this in an irreversible way for efficiency. Factor out some common code for the reversible translation. This is slightly simpler now, and much easier to expand. Translate the magic flags value -1 to a single control flag internally up front so other flags can be trusted later. This can be used for the relevant ioctl() too. Remove CONS_CURSOR_FLAGS which contained all the control flags. It was unused and not useful. After adding more flags, there will be tests on a couple at a time but never on them all. This API should have used this to disallow unknown flags.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter.

Now we don't have to set `hint.sc.0.vesa_mode' to get the default palette data. - Add a new adapter flag, V_ADP_DAC8 to track whether the controller is using 8-bit palette format and load correct palette when switching modes. - Set 8-bit DAC mode only for non-VGA compatible graphics mode.

Just because we have a serial console attached does not mean we don't want a splash screen. There seems to be some confusion in the syscons code as to the meaning of the SC_KERNEL_CONSOLE flag. Its absence is sometimes interpreted to mean "I am not the system console", and sometimes to mean "I am not the only VGA console" (see the font loading code for an example of the latter). Someone with better syscons fu than myself should take a closer look.

Quick fix for locking fixes in r172250. The lock added there was per- virtual-device, but needs to be per-physical-device so that it protects shared data. Usually, scp->sc->write_in_progress got corrupted first and further corruption was limited when this variable was left at nonzero with no write in progress. Attempt to fix missing lock destruction in r162285. Put it with the lock destruction for r172250 after moving the latter. Both might be unreachable. To demonstrate the bug, find a buggy syscall or sysctl that calls printf(9) and run this often. Run hd /dev/zero >/dev/ttyvN for any N != 0. The console spam goes to ttyv0 and the non-console spam goes to ttyvN, so the lock provided no protection (but it helped for N == 0).

The switch to kernel terminal context needs to update more than the cursor position. Especially the screen size, and potentially everything except the input state and attributes. Do this by changing the cursor position setting method to a general syncing method. Use proper constructors instead of copying to create kernel terminal contexts. We really want clones and not new instances, but there is no method for cloning and there is nothing in the active instance that needs to be cloned exactly. Add proper destructors for kernel terminal contexts. I doubt that the destructor code has every been reached, but if it was then it leaked the memory of the clones. Remove freeing of statically allocated memory for the non-kernel terminal context for the same terminal as the kernel. This is in the nearly unreachable code. This used to not happen because delicate context swapping made the user context use the dynamic memory and kernel context the static memory. I didn't restore this swapping since it would have been unnatural to have all kernel contexts except 1 dynamic. The constructor for terminal context has bad layering for reasons related to the bug. It has to return static memory early before malloc() works. Callers also can't allocate memory until after the first constructor selects an emulator and tells upper layers the size of its context. After that, the cloning hack required the cloning code to allocate the memory, but for all other constructors it would be better for the terminal layer to allocate and deallocate the memory in all cases. Zero the memory when allocating terminal contexts dynamically.

Make comp_vgaregs() less strict about VGA register values when checking the BIOS video mode paramter table. Now syscons uses the parameter table even if some bits in the table are different from the current VGA register settings. Even if comp_vgaregs() finds that the BIOS video parameter table looks totally unfamiliar to it, syscons allows the user to change the current video mode to some modes which are based on the VGA 80x25 mode. They are VGA 80x30, VGA 80x50, VGA 80x60. In this case the user will be warned, during boot, that video mode switching is only paritally supported on his machine. PR: bin/4477

First round in syscons update. Several new features has been added: No kernel config options anymore besides keyboard language layout. Virtual consoles are now dynamically allocated, no NCONS anymore. Software cursor blinking/nonblinking. Visual bell for laptops (don't beep at meetings :-). Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

Next syscons update (given up on numbering :) Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

Add VESA support to syscons. Kazu writes: The VESA support code requires vm86 support. Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Factor out some common code for the reversible translation. This is slightly simpler now, and much easier to expand. Translate the magic flags value -1 to a single control flag internally up front so other flags can be trusted later. This can be used for the relevant ioctl() too. Remove CONS_CURSOR_FLAGS which contained all the control flags. It was unused and not useful. After adding more flags, there will be tests on a couple at a time but never on them all. This API should have used this to disallow unknown flags.

The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Start fixing some bugs in attribute handling. This change just does cleanups missed in r56043 17 years ago. The default attributes were still stored in structs for the purpose of changing them and passing around pointers to the defaults, but r56043 added another layer that made the defaults invariant and only used for initialization and reset. Just use the defaults directly. This was already done for the kernel defaults. The defaults for reverse attributes aren't actually used, but are ignored in layers that no longer support them.

Use the calibrated/adjustable i8254 frequency `timer_freq' instead of TIMER_FREQ. Fixed missing splx() in scrn_timer(). The bug was harmless because of the undocumented behaviour that the ipl is automatically restored for timeout functions (see softclock()). Perhaps we should depend on this behaviour. Fixed the ddb fix in rev.1.176. The in_debugger flag was no use because it only works when the debugger is entered via the keyboard hotkey. The debugger may be entered for breakpoints and traps, and the console putc routine has no way of knowing when it was, so the console putc routine must (almost?) always remove the cursor image. Not fixed: console switching in ddb doesn't work (ISTR it working), and console 0 shouldn't be switched to for the debugger hotkey unless console 0 is /dev/console. Fixed side effects from calling add_keyboard_randomness() in the console getc routine by not calling it. add_keyboard_randomness() currently always reenables interrupts on 386's and 486's. This is very bad if the console getc routine is called from the debugger and the debugger was entered with interrupts disabled. Fixed preservation of initial screen and now-bogus comment about it. It was broken by setting the initial scr_buf to `buffer' instead of Crtat. `buffer' was full of nulls and the first scroll cleared everything above the things written through syscons.

Add some locking to sc_cngetc(). Keyboard input needs Giant locking, and that is not possible to do correctly here. Use mtx_trylock() and proceed unlocked as before if we can't acquire Giant (non-recursively), except in kdb mode don't even try to acquire Giant. Everything here is a hack, but it often works. Even if mtx_trylock() succeeds, this might be a LOR. Keyboard input also needs screen locking, to handle screen updates and switches. Add this, using the same simplistic screen locking as for sc_cnputc(). Giant must be acquired before the screen lock, and the screen lock must be dropped when calling the keyboard driver (else it would get a harmless LOR if it tries to acquire Giant). It was intended that sc cn open/close hide the locking calls, and they do for i/o functions functions except for this complication. Non-console keyboard input is still only Giant-locked, with screen locking in some called functions. This is correct for the keyboard parts only. When Giant cannot be acquired properly, atkbd and kbdmux tend to race and work (they assume that the caller acquired Giant properly and don't try to acquire it again or check that it has been acquired, and the races rarely matter), while ukbd tends to deadlock or panic (since it does the opposite, and has other usb threads to deadlock with). The keyboard (Giant) locking here does very little, but the screen locking completes screen locking for console mode except for not detecting or handling deadlock.

Huge cleanup of random(4) code. * GENERAL - Update copyright. - Make kernel options for RANDOM_YARROW and RANDOM_DUMMY. Set neither to ON, which means we want Fortuna - If there is no 'device random' in the kernel, there will be NO random(4) device in the kernel, and the KERN_ARND sysctl will return nothing. With RANDOM_DUMMY there will be a random(4) that always blocks. - Repair kern.arandom (KERN_ARND sysctl). The old version went through arc4random(9) and was a bit weird. - Adjust arc4random stirring a bit - the existing code looks a little suspect. - Fix the nasty pre- and post-read overloading by providing explictit functions to do these tasks. - Redo read_random(9) so as to duplicate random(4)'s read internals. This makes it a first-class citizen rather than a hack. - Move stuff out of locked regions when it does not need to be there. - Trim RANDOM_DEBUG printfs. Some are excess to requirement, some behind boot verbose. - Use SYSINIT to sequence the startup. - Fix init/deinit sysctl stuff. - Make relevant sysctls also tunables. - Add different harvesting "styles" to allow for different requirements (direct, queue, fast). - Add harvesting of FFS atime events. This needs to be checked for weighing down the FS code. - Add harvesting of slab allocator events. This needs to be checked for weighing down the allocator code. - Fix the random(9) manpage. - Loadable modules are not present for now. These will be re-engineered when the dust settles. - Use macros for locks. - Fix comments. * src/share/man/... - Update the man pages. * src/etc/... - The startup/shutdown work is done in D2924. * src/UPDATING - Add UPDATING announcement. * src/sys/dev/random/build.sh - Add copyright. - Add libz for unit tests. * src/sys/dev/random/dummy.c - Remove; no longer needed. Functionality incorporated into randomdev.*. * live_entropy_sources.c live_entropy_sources.h - Remove; content moved. - move content to randomdev.[ch] and optimise. * src/sys/dev/random/random_adaptors.c src/sys/dev/random/random_adaptors.h - Remove; plugability is no longer used. Compile-time algorithm selection is the way to go. * src/sys/dev/random/random_harvestq.c src/sys/dev/random/random_harvestq.h - Add early (re)boot-time randomness caching. * src/sys/dev/random/randomdev_soft.c src/sys/dev/random/randomdev_soft.h - Remove; no longer needed. * src/sys/dev/random/uint128.h - Provide a fake uint128_t; if a real one ever arrived, we can use that instead.

Flesh out the state and flags args to sccnopen(). Set state flags to indicate (potentially partial) success of the open. Use these to decide what to close in sccnclose(). Only grab/ungrab use open/close so far. Add a per-sc variable to count successful keyboard opens and use this instead of the grab count to decide if the keyboad state has been switched. Start fixing the locking by using atomic ops for the most important counter -- the grab level one. Other racy counting will eventually be fixed by normal mutex or kdb locking in most cases. Use a 2-entry per-sc stack of states for grabbing. 2 is just enough to debug grabbing, e.g., for gets(). gets() grabs once and might not be able to do a full (or any) state switch. ddb grabs again and has a better chance of doing a full state switch and needs a place to stack the previous state. For more than 3 levels, grabbing just changes the count. Console drivers should try to switch on every i/o in case lower levels of nesting failed to switch but the current level succeeds, but then the switch (back) must be completed on every i/o and this flaps the state unless the switch is null. The main point of grabbing is to make it null quite often. Syscons grabbing also does a carefully chosen screen focus that is not done on every i/o. Add a large comment about grabbing. Restore some small lost comments.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Disable some more unsafe things in (low level) console mode: - never call up to the tty layer to restart output for keyboard input in console mode. This was already disallowed in kdb mode. Other cases are rarely reached. - disable the reboot, halt and powerdown keys in console mode. The suspend, standby and panic keys are still allowed, and aren't even conditonal on excessive configuration options. Some of these actions are still available in ddb mode as ddb commands which are equally unsafe. Some are useful at input prompts and should be restored when the locking is fixed. - disallow bells in kdb mode (should be in console mode, but the flag for that is not available). Visual bell gives very alarming behaviour by trying to use callouts which don't work in kdb mode. Audio bell uses timeouts and hardware resources with mutexes that can deadlock in reasonable use of ddb. Screen switches in kdb mode are not very safe, but they are important functionality and there is a lot of code to make them sort of work.

/* Only safe in Giant-locked context. */
Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

The first stage of console driver reorganization: activate new keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV.

PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen.

This option replaces the existing STD8X16FONT option, which loads 16-line font data only. - The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c. - The video driver provides a set of ioctl commands to manipulate the frame buffer. - New kernel configuration option: VGA_WIDTH90 Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are mot always supported by the video card. PR: i386/7510 Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx. - The header file machine/console.h is reorganized; its contents is now split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h (another new file). machine/console.h is still maintained for compatibility reasons. - Kernel console selection/installation routines are fixed and slightly rebumped so that it should now be possible to switch between the interanl kernel console (sc or vt) and a remote kernel console (sio) again, as it was in 2.x, 3.0 and 3.1. - Screen savers and splash screen decoders Because of the header file reorganization described above, screen savers and splash screen decoders are slightly modified.

Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers.

Attempt to make break-to-debugger and alternative break-to-debugger more accessible: (1) Always compile in support for breaking into the debugger if options KDB is present in the kernel. (2) Disable both by default, but allow them to be enabled via tunables and sysctls debug.kdb.break_to_debugger and debug.kdb.alt_break_to_debugger. (3) options BREAK_TO_DEBUGGER and options ALT_BREAK_TO_DEBUGGER continue to behave as before -- only now instead of compiling in break-to-debugger support, they change the default values of the above sysctls to enable those features by default. Current kernel configurations should, therefore, continue to behave as expected. (4) Migrate alternative break-to-debugger state machine logic out of individual device drivers into centralised KDB code. This has a number of upsides, but also one downside: it's now tricky to release sio spin locks when entering the debugger, so we don't. However, similar logic does not exist in other device drivers, including uart. (5) dcons requires some special handling; unlike other console types, it allows overriding KDB's own debugger selection, so we need a new interface to KDB to allow that to work. GENERIC kernels in -CURRENT will now support break-to-debugger as long as appropriate boot/run-time options are set, which should improve the debuggability of BETA kernels significantly.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Now syscons uses the parameter table even if some bits in the table are different from the current VGA register settings. Even if comp_vgaregs() finds that the BIOS video parameter table looks totally unfamiliar to it, syscons allows the user to change the current video mode to some modes which are based on the VGA 80x25 mode. They are VGA 80x30, VGA 80x50, VGA 80x60. In this case the user will be warned, during boot, that video mode switching is only paritally supported on his machine. PR: bin/4477

Add VESA mode support for syscons, which enables the support of 15, 16, 24, and 32 bit modes. To use that, syscons(4) must be built with the compile time option 'options SC_PIXEL_MODE', and VESA support (a.k.a. vesa.ko) must be either loaded, or be compiled into the kernel. Do not return EINVAL when the mouse state is changed to what it already is, which seems to cause problems when you have two mice attached, and applications are not likely obtain useful information through the EINVAL caused by showing the mouse pointer twice. Teach vidcontrol(8) about mode names like MODE_<NUMBER>, where <NUMBER> is the video mode number from the vidcontrol -i mode output. Also, revert the video mode if something fails.

Addresses the following two problems. 1) i586_bcopy() problem There have been a number of reports that the syscons doesn't work properly if i586_bcopy() is enabled. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is that the system looks frozen during device probe or just before the main installation menu. The workaround was to specify the flag 0x01 to the npx device so that i586_bcopy() is disabled. The patch forces the syscons to call generic_bcopy() when copying to/from the video memory, even if CPU is Pentium and i586_bcopy() is enabled. i586_bcopy() is still called for copy operations between non-video memory regions. PR: kern/2277, kern/3066, kern/3107, kern/3134 2) video mode parameter table problem The syscons reads and uses the video mode parameter table provided by the VGA BIOS to set VGA registers when changing video mode and modifying font data. It appears that in some VGA BIOSes the table is not ordered as the syscons expects, and this leads to screen corruption. The problem prevented users from installing 2.2(.1)-RELEASE. The symptom is the corrupt screen or strange vertical lines soon after the kernel is loaded into memory (just after the kernel decompression). The patch performs simplistic test and if it fails, set video_mode_ptr to NULL so that the video mode switching won't happen. This is an interim kludge. There should be a better way to deal with the problem. PR: kern/2498, conf/2775, conf/3354 Reviewed by: sos Tested by: PR originators (not all of them, though)

Replace syscons terminal renderer by a new renderer that uses libteken. Some time ago I started working on a library called libteken, which is terminal emulator. It does not buffer any screen contents, but only keeps terminal state, such as cursor position, attributes, etc. It should implement all escape sequences that are implemented by the cons25 terminal emulator, but also a fair amount of sequences that are present in VT100 and xterm. A lot of random notes, which could be of interest to users/developers: - Even though I'm leaving the terminal type set to `cons25', users can do experiments with placing `xterm-color' in /etc/ttys. Because we only implement a subset of features of xterm, this may cause artifacts. We should consider extending libteken, because in my opinion xterm is the way to go. Some missing features: - Keypad application mode (DECKPAM) - Character sets (SCS) - libteken is filled with a fair amount of assertions, but unfortunately we cannot go into the debugger anymore if we fail them. I've done development of this library almost entirely in userspace. In sys/dev/syscons/teken there are two applications that can be helpful when debugging the code: - teken_demo: a terminal emulator that can be started from a regular xterm that emulates a terminal using libteken. This application can be very useful to debug any rendering issues. - teken_stress: a stress testing application that emulates random terminal output. libteken has literally survived multiple terabytes of random input. - libteken also includes support for UTF-8, but unfortunately our input layer and font renderer don't support this. If users want to experiment with UTF-8 support, they can enable `TEKEN_UTF8' in teken.h. If you recompile your kernel or the teken_demo application, you can hold some nice experiments. - I've left PC98 the way it is right now. The PC98 platform has a custom syscons renderer, which supports some form of localised input. Maybe we should port PC98 to libteken by the time syscons supports UTF-8? - I've removed the `dumb' terminal emulator. It has been broken for years. It hasn't survived the `struct proc' -> `struct thread' conversion. - To prevent confusion among people that want to hack on libteken: unlike syscons, the state machines that parse the escape sequences are machine generated. This means that if you want to add new escape sequences, you have to add an entry to the `sequences' file. This will cause new entries to be added to `teken_state.h'. - Any rendering artifacts that didn't occur prior to this commit are by accident. They should be reported to me, so I can fix them.

- Add support for the following mice to psm/moused/sysmouse: MS IntelliMouse, Kensington Thinking Mouse, Genius NetScroll, Genius NetMouse, Genius NetMouse Pro, ALPS GlidePoint, ASCII MieMouse, Logitech MouseMan+, FirstMouse+ - The `psm' driver is made to recognize various models of PS/2 mice and enable their extra features so that their additional buttons and wheel/roller are recognized. The name of the detected model will be printed at boot time. - A set of new ioctl functions are added to the `psm', `mse' and `sysmouse' drivers so that the userland program (such as the X server) can query device information and change driver settings. - The wheel/roller movement is handled as the `Z' axis movement by the mouse drivers and the moused daemon. The Z axis movement may be mapped to another axis movement or buttons. - The mouse drivers support a new, standard mouse data format, MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement and up to 10 buttons. /sys/i386/include/mouse.h - Added some fields to `mousestatus_t' to store Z axis movement and flag bits. - Added the field `model' to `mousehw_t' to store mouse model code. Defined model codes. - Extended `mousemode_t'. - Added new protocols and some constants for them. - Added new ioctl functions and structures. - Removed obsolete ioctl definitions. /sys/i386/include/console.h - Added `dz' field to the structure `mouse_data' to pass Z axis movement to `syscons/sysmouse'. - Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON. Use button bits defined in `mouse.h' instead. /sys/i386/isa/psm.c - Added a set of functions to detect various mice which have additional features (wheel and buttons) unavailable in the standard PS/2 mouse. - Refined existing ioctl functions and added new ones. Most important of all is MOUSE_SETLEVEL which manipulates the output level of the driver. While the output level remains zero, the output from the `psm' driver is in the standard PS/2 mouse format (three bytes long). When the level is set to one, the `psm' driver will send data in the extended format. At the level two the driver uses the format which is native to the connected mouse is used. (Meaning that the output from the device is passed to the caller as is, unmodified.) The `psm' driver will pass such extended data format as is to the caller if the output level is two, but emulates the standard format if the output level is zero. - Added kernel configuration flags to set initial resolution (PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL). - Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION. Acceleration ratio is now specified by the kernel configuration flags stated above. Sync check logic is refined and now standard. The sync check can be turned off by the new kernel configuration flags PSM_CONFIG_NOCHECKSYNC (0x100). PSM_EMULATION has been of little use. - Summer clean up :-) Removed unused code and obsolete comments. /sys/i386/isa/mse.c - Created mseioctl() to deal with ioctl functions MOUSE_XXXX. Most importantly, the MOUSE_SETLEVEL ioctl will change the output format from the 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Use constants defined in `mouse.h' rather than magic numbers. /sys/i386/isa/syscons.c - Changed scioctl() to reflect the new `console.h' and some of the new ioctls defined in `mouse.h'. Most importantly, the MOUSE_SETLEVEL ioctl will change the `sysmouse' output format from the MouseSystems 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Added support for double/triple click actions of the left button and single click action of the right button in the virtual console. The left button double click will select a word under the mouse pointer. The triple click will select a line and the single click of the right button will extend the selected region to the current position of the mouse pointer. This will make the cut/paste support more compatible with xterm. /sys/i386/isa/kbdio.h - Added PSM_INTELLI_ID.

The second phase of syscons reorganization. - Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV. When this key is pressed, the vty immediately before the current vty will become foreground. Analogue to PREV, which is usually assigned to the PrntScrn key. PR: kern/10113 Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de> - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen. Submitted by: Nick Hibma (n_hibma@FreeBSD.ORG) SC_DFLT_FONT makeoptions "SC_DFLT_FONT=_font_name_" Include the named font as the default font of syscons. 16-line, 14-line and 8-line font data will be compiled in. This option replaces the existing STD8X16FONT option, which loads 16-line font data only. - The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c. - The video driver provides a set of ioctl commands to manipulate the frame buffer. - New kernel configuration option: VGA_WIDTH90 Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are mot always supported by the video card. PR: i386/7510 Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx. - The header file machine/console.h is reorganized; its contents is now split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h (another new file). machine/console.h is still maintained for compatibility reasons. - Kernel console selection/installation routines are fixed and slightly rebumped so that it should now be possible to switch between the interanl kernel console (sc or vt) and a remote kernel console (sio) again, as it was in 2.x, 3.0 and 3.1. - Screen savers and splash screen decoders Because of the header file reorganization described above, screen savers and splash screen decoders are slightly modified. After this update, /sys/modules/syscons/saver.h is no longer necessary and is removed.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

Add support for VT200-style mouse input. Right now if applications want to use the mouse on the command line, they use sysmouse(4) and install a signal handler in the kernel to deliver signals when mouse events arrive. This conflicts with my plan to change to TERM=xterm, so implement proper VT200-style mouse input. Because mouse input is now streamed through the TTY, it means you can now SSH to another system on the console and use the mouse there as well. The disadvantage of the VT200 mouse protocol, is that it doesn't seem to generate events when moving the cursor. Only when pressing and releasing mouse buttons. There are different protocols as well, but this one seems to be most commonly supported. Reported by: Paul B. Mahol <onemda gmail com> Tested with: vim(1)

If users want to experiment with UTF-8 support, they can enable `TEKEN_UTF8' in teken.h. If you recompile your kernel or the teken_demo application, you can hold some nice experiments. - I've left PC98 the way it is right now. The PC98 platform has a custom syscons renderer, which supports some form of localised input. Maybe we should port PC98 to libteken by the time syscons supports UTF-8? - I've removed the `dumb' terminal emulator. It has been broken for years. It hasn't survived the `struct proc' -> `struct thread' conversion. - To prevent confusion among people that want to hack on libteken: unlike syscons, the state machines that parse the escape sequences are machine generated. This means that if you want to add new escape sequences, you have to add an entry to the `sequences' file. This will cause new entries to be added to `teken_state.h'. - Any rendering artifacts that didn't occur prior to this commit are by accident. They should be reported to me, so I can fix them.

Add support for VT200-style mouse input. Right now if applications want to use the mouse on the command line, they use sysmouse(4) and install a signal handler in the kernel to deliver signals when mouse events arrive. This conflicts with my plan to change to TERM=xterm, so implement proper VT200-style mouse input. Because mouse input is now streamed through the TTY, it means you can now SSH to another system on the console and use the mouse there as well. The disadvantage of the VT200 mouse protocol, is that it doesn't seem to generate events when moving the cursor. Only when pressing and releasing mouse buttons. There are different protocols as well, but this one seems to be most commonly supported. Reported by: Paul B. Mahol <onemda gmail com> Tested with: vim(1)

Replace syscons terminal renderer by a new renderer that uses libteken. Some time ago I started working on a library called libteken, which is terminal emulator. It does not buffer any screen contents, but only keeps terminal state, such as cursor position, attributes, etc. It should implement all escape sequences that are implemented by the cons25 terminal emulator, but also a fair amount of sequences that are present in VT100 and xterm. A lot of random notes, which could be of interest to users/developers: - Even though I'm leaving the terminal type set to `cons25', users can do experiments with placing `xterm-color' in /etc/ttys. Because we only implement a subset of features of xterm, this may cause artifacts. We should consider extending libteken, because in my opinion xterm is the way to go. Some missing features: - Keypad application mode (DECKPAM) - Character sets (SCS) - libteken is filled with a fair amount of assertions, but unfortunately we cannot go into the debugger anymore if we fail them. I've done development of this library almost entirely in userspace. In sys/dev/syscons/teken there are two applications that can be helpful when debugging the code: - teken_demo: a terminal emulator that can be started from a regular xterm that emulates a terminal using libteken. This application can be very useful to debug any rendering issues. - teken_stress: a stress testing application that emulates random terminal output. libteken has literally survived multiple terabytes of random input. - libteken also includes support for UTF-8, but unfortunately our input layer and font renderer don't support this.

This is the 3rd stage of syscons code reorganization. - Split terminal emulation code from the main part of the driver so that we can have alternative terminal emulator modules if we like in the future. (We are not quite there yet, though.) - Put sysmouse related code in a separate file, thus, simplifying the main part of the driver. As some files are added to the source tree, you need to run config(8) before you compile a new kernel next time. You shouldn't see any functional change by this commit; this is only internal code reorganization.

Disable some more unsafe things in (low level) console mode: - never call up to the tty layer to restart output for keyboard input in console mode. This was already disallowed in kdb mode. Other cases are rarely reached. - disable the reboot, halt and powerdown keys in console mode. The suspend, standby and panic keys are still allowed, and aren't even conditonal on excessive configuration options. Some of these actions are still available in ddb mode as ddb commands which are equally unsafe. Some are useful at input prompts and should be restored when the locking is fixed. - disallow bells in kdb mode (should be in console mode, but the flag for that is not available). Visual bell gives very alarming behaviour by trying to use callouts which don't work in kdb mode. Audio bell uses timeouts and hardware resources with mutexes that can deadlock in reasonable use of ddb. Screen switches in kdb mode are not very safe, but they are important functionality and there is a lot of code to make them sort of work.

The "free-lance" timer in the i8254 is only used for the speaker these days, so de-generalize the acquire_timer/release_timer api to just deal with speakers. The new (optional) MD functions are: timer_spkr_acquire() timer_spkr_release() and timer_spkr_setfreq() the last of which configures the timer to generate a tone of a given frequency, in Hz instead of 1/1193182th of seconds. Drop entirely timer2 on pc98, it is not used anywhere at all. Move sysbeep() to kern/tty_cons.c and use the timer_spkr*() if they exist, and do nothing otherwise. Remove prototypes and empty acquire-/release-timer() and sysbeep() functions from the non-beeping archs. This eliminate the need for the speaker driver to know about i8254frequency at all. In theory this makes the speaker driver MI, contingent on the timer_spkr_*() functions existing but the driver does not know this yet and still attaches to the ISA bus. Syscons is more tricky, in one function, sc_tone(), it knows the hz and things are just fine. In the other function, sc_bell() it seems to get the period from the KDMKTONE ioctl in terms if 1/1193182th second, so we hardcode the 1193182 and leave it at that. It's probably not important. Change a few other sysbeep() uses which obviously knew that the argument was in terms of i8254 frequency, and leave alone those that look like people thought sysbeep() took frequency in hertz. This eliminates the knowledge of i8254_freq from all but the actual clock.c code and the prof_machdep.c on amd64 and i386, where I think it would be smart to ask for help from the timecounters anyway [TBD].

Cursor/bell default type setable via config "flags" instead of as defines. Cursor/bell type setable via ioctl's. New video modes 80x30 80x60 for some laptops, and those with multisync monitors. Scroll-lock history (length currently fixed at 100 lines). Lots of cleanups, some only commented out for now (will goaway soon). Support for new features in vidcontrol/kbdcontrol. Updated manpages.

Restore switching to a separate kernel terminal "input" state and extend it to a separate state for each CPU. Terminal "input" is user or kernel output. Its state includes the current parser state for escape sequences and multi-byte characters, and some results of previous parsing (mainly attributes), and in teken the cursor position, but not completed output. This state must be switched for kernel output since the kernel can preempt anything, including itself, and this must not affect the preempted state more than necessary. Since vty0 is shared, it is necessary to affect the frame buffer and cursor position and history, but escape sequences must not be affected and attributes for further output must not be affected. This used to work. The syscons terminal state contained mainly the parser state for escape sequences and attributes, but not the cursor position, and was switched. This was first broken by SMP and/or preemptive kernels. Then there should really be a separate state for each thread, and one more for ddb, or locking to prevent preemption. Serialization of printf() helps. But it is arcane that full syscons escape sequences mostly work in kernel printf(), and I have never seen them used except by me to test this fix. They worked perfectly except for the races, since "input" from the kernel was not special in any way. This was broken to use teken. The general switch was removed, and the kernel normal attribute was switched specially. The kernel reverse attribute (config option SC_CONS_REVERSE_ATTR) became unused, and is still unusable because teken doesn't support default reverse attributes (it used to only be used via the ANSI escape sequence to set reverse video). The only new difficulty for using teken seems to be that the cursor position is in the "input" state, so it must be updated in the active input state for each half of the switch. Do this to complete the restoration. The per-CPU state is mainly to make per-CPU coloring work cleanly, at a cost of some space. Each CPU gets its own full set of attribute (not just the current attribute) maintained in the usual way. This also reduces races from unserialized printf()s. However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Colorize syscons kernel console output according to a table indexed by the CPU number. This was originally for debugging near-deadlock conditions where multiple CPUs either deadlock or scramble each other's output trying to report the problem, but I found it interesting and sometimes useful for ordinary kernel messages. Ordinary kernel messages shouldn't be interleaved, but if they are then the colorization makes them readable even if the interleaving is for every character (provided the CPU printing each message doesn't change). The default colors are 8-15 starting at 15 (bright white on black) for CPU 0 and repeating every 8 CPUs. This works best with 8 CPUs. Non-bright colors and nonzero background colors need special configuration to avoid unreadable and ugly combinations so are not configured by default. The next bright color after 15 is 8 (bright black = dark gray) is not very readable but is the only other color used with 2 CPUs. After that the next bright color is 9 (bright blue) which is not much brighter than bright black, but is used with 3+ CPUs. Other bright colors are brighter. Colorization is configured by default so that it gets tested. It can only be turned off by configuring SC_KERNEL_CONS_ATTR to anything other than FG_WHITE. After booting, all colors can be changed using the syscons.kattr sysctl. This is a SYSCTL_OPAQUE, and no utility is provided to change it (sysctl only displays it). The default colors work in all VGA modes that I could test. In 2-color graphics modes, all 8 bright colors are displayed as bright white, so the colorization has no effect, but anything with a nonzero background gives white on white unless the foreground is zero. I don't have an mono or VGA grayscale hardware to test on. Support for mono mode seems to have never worked right in syscons (I think bright white gives white underline with either bold or bright), but VGA grayscale should work better than 2-color graphics.

However, this gives races for serialized printf()s that otherwise have none. Nothing prevents the CPU doing the a printf() changing in the middle of an escape sequence.

Fix bugs in (mostly) not-yet-activated parts of early/emergency output: - map the hard-coded frame buffer address above KERNBASE. Using the physical address only worked because of larger mapping bugs. The hard-coded frame buffer address only works on x86. Use messy ifdefs to try to avoid warnings about unused code for other arches. - remove the sysctl for reading and writing the table kernel console attributes. Writing only worked for emergency output since normal output uses unalterd copies. - fix the test for the emergency console being usable - explain why a hard-coded attribute is used very early. Emergency output works on x86 even before the pcpu pointer is initialized.

Colorize syscons kernel console output according to a table indexed by the CPU number. This was originally for debugging near-deadlock conditions where multiple CPUs either deadlock or scramble each other's output trying to report the problem, but I found it interesting and sometimes useful for ordinary kernel messages. Ordinary kernel messages shouldn't be interleaved, but if they are then the colorization makes them readable even if the interleaving is for every character (provided the CPU printing each message doesn't change). The default colors are 8-15 starting at 15 (bright white on black) for CPU 0 and repeating every 8 CPUs. This works best with 8 CPUs. Non-bright colors and nonzero background colors need special configuration to avoid unreadable and ugly combinations so are not configured by default. The next bright color after 15 is 8 (bright black = dark gray) is not very readable but is the only other color used with 2 CPUs. After that the next bright color is 9 (bright blue) which is not much brighter than bright black, but is used with 3+ CPUs. Other bright colors are brighter. Colorization is configured by default so that it gets tested. It can only be turned off by configuring SC_KERNEL_CONS_ATTR to anything other than FG_WHITE. After booting, all colors can be changed using the syscons.kattr sysctl. This is a SYSCTL_OPAQUE, and no utility is provided to change it (sysctl only displays it). The default colors work in all VGA modes that I could test. In 2-color graphics modes, all 8 bright colors are displayed as bright white, so the colorization has no effect, but anything with a nonzero background gives white on white unless the foreground is zero. I don't have an mono or VGA grayscale hardware to test on. Support for mono mode seems to have never worked right in syscons (I think bright white gives white underline with either bold or bright), but VGA grayscale should work better than 2-color graphics.

The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system. The last half year I've been working on a replacement TTY layer for the FreeBSD kernel. The new TTY layer was designed to improve the following: - Improved driver model: The old TTY layer has a driver model that is not abstract enough to make it friendly to use. A good example is the output path, where the device drivers directly access the output buffers. This means that an in-kernel PPP implementation must always convert network buffers into TTY buffers. If a PPP implementation would be built on top of the new TTY layer (still needs a hooks layer, though), it would allow the PPP implementation to directly hand the data to the TTY driver. - Improved hotplugging: With the old TTY layer, it isn't entirely safe to destroy TTY's from the system. This implementation has a two-step destructing design, where the driver first abandons the TTY. After all threads have left the TTY, the TTY layer calls a routine in the driver, which can be used to free resources (unit numbers, etc). The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

The pts(4) driver also implements this feature, which means posix_openpt() will now return PTY's that are created on the fly. - Improved performance: One of the major improvements is the per-TTY mutex, which is expected to improve scalability when compared to the old Giant locking. Another change is the unbuffered copying to userspace, which is both used on TTY device nodes and PTY masters. Upgrading should be quite straightforward. Unlike previous versions, existing kernel configuration files do not need to be changed, except when they reference device drivers that are listed in UPDATING.

return (SC_STAT(tp));
Rearrangements needed for syscons(4) to be used as a console device on architectures that need to call cninit() before the machine is ready to support mutexes (required by make_dev()). - Remove make_dev() call from scinit() when flags indicate unit is the system console, rely on sc_attach_unit() to handle it. - When trying to access current screen's status (scr_stat structure) use the static one provided for the initial system console if no dev_t is available. - When calling make_dev() in sc_attach_unit() catch special case of system's initial console and set up dev_t structure to include pointer to console's scr_stat struct.

Integrate kbdmux(4) into syscons(4) and kbd code. By default syscons(4) will look for the kbdmux(4) keyboard first, and then, if not found, look for any keyboard. Current kbd code is modified so if kbdmux(4) is the current keyboard, all new keyboards are automatically added to the kbdmux(4). Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at the loader prompt, or at runtime, by kldload'ing the kbdmux module and releasing current active keyboard. If, for whatever reason, kbdmux(4) is not required/desired then just do not load it and everything should work as before. It is also possible to kldunload kbdmux at runtime and syscons(4) will automatically switch to the first available keyboard. No response from: freebsd-current@ MFC after: 1 day
