49ff4debd3 Spring cleaning around strategy and disklabels/slices:
Introduce BUF_STRATEGY(struct buf *, int flag) macro, and use it throughout.
please see comment in sys/conf.h about the flag argument.

Remove strategy argument from all the diskslice/label/bad144
implementations, it should be found from the dev_t.

Remove bogus and unused strategy1 routines.

Remove open/close arguments from dssize().  Pick them up from dev_t.

Remove unused and unfinished setgeom support from diskslice/label/bad144 code.

15317dd875 Alter the behavior of sys/kern/subr_bus.c:device_print_child()
- device_print_child() either lets the BUS_PRINT_CHILD
	  method produce the entire device announcement message or
	  it prints "foo0: not found\n"

Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)

Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())

The BUS_PRINT_CHILD method now returns int instead of void.

Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.

	- Devices are 'on' a bus, not 'at' it.
	- If a custom BUS_PRINT_CHILD method does the same thing
	  as bus_generic_print_child(), use bus_generic_print_child()
	- Use device_get_nameunit() instead of both
	  device_get_name() and device_get_unit()
	- All BUS_PRINT_CHILD methods return the number of
	  characters output.

e33bfde398 We're called too early to have any idea whether APM is going to be
active or not.  The only sane thing we can do here is assume that if
APM is supported it might be active at some point, and bail.

In reality, even this isn't good enough; regardless of whether we support
APM or not, the system may well futz with the CPU's clock speed and throw
the TSC off.  We need to stop using it for timekeeping except under
controlled circumstances.  Curse the lack of a dependable high-resolution
timer.

9840e7cb5a This commit gives support for the Rise mP6 CPU. It has two changes:
1. Rise is recognized in identdcpu.c.
	2. The TSC is not written to. A workaround for the CPU bug is being
	   applied to clock.c (the bug being that the mP6 has TSC enabled
	   in its CPUID-capabilities, but it only supports reading it. If we
	   try to write to it (MSR 16), a GPF occurs.) The new behavior is that
	   FreeBSD will _not_ zero the TSC. Instead, we do a bit of 64-bit
	   arithmetic.

6e8394b8ba 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.

  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.

- 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.

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

Bruce Evans
b50641ef9c Fixed glitches (jumps) of about 1/HZ seconds for the i8254 timecounter.
The old version only worked right when the time was read strictly
more often than every 1/HZ seconds, but we only guarantee reading
it every (1/HZ + epsilon) seconds.  Part of rev.1.126-1.127 attempted
to fix this but didn't succeed.  Detect counter rollover using the
heuristic from the old version of microtime() with additional
complications for supporting calls from fast interrupt handlers.
This works provided i8254 interrupts are not delayed by more than
1/(2*HZ) seconds.

This needs more comments, and cleanups for the SMP case, and more
testing of the SMP case before it is merged into RELENG_3.

Mark the GDB port in the config file with flags 0x80. Currently
only the sio driver checks these flags and sets up a GDB port,
but adding similar code to other serial drivers would be easy.
For backward compatibility, if an sio port is marked as the console
and no port is marked as the gdb port, the GDB port will be mapped
to the console port. This hack should go away at some point.

f711d546d2 Suser() simplification:
1:

2:

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.

54a8c69347 Stage 1 of a cleanup of the i386 interrupt registration mechanism.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager.  There is further room for optimizing
the interfaces still.  All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.

0f6bc47029 Make the bt isa driver work..
- fix cut/paste problem. :-)
- don't forget to call isa_dmacascade()
- reset the port after we release resources.

That last one is a trap to watch out for..  The isa bus driver uses the
same port/irq/mem/etc variables for the initial probe hints as it does
for allocation/deallocation tracking.  Releasing a resource clears the
variable and then you loose the hint during attach.. (ouch!)

a49a3d4433 Implement an EISA new-bus framework. The old driver probe mechanism
had a quirk that made a shim rather hard to implement properly and it was
just easier to convert the drivers in one go.  The changes to the
buslogic driver go beyond just this - the whole driver was new-bus'ed
including pci and isa.  I have only tested the EISA part of this so far.

6182fdbda8 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.

e9deda23ae Keyboard driver update in preparation for the USB keyboard driver.
- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
  ATKBD_DFLT_KEYMAP
  Specify a keymap to be used as the default, built-in keymap.
  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
  These options are now gone for good.  The new option is more general.)

  KBD_DISABLE_KEYMAP_LOADING
  Don't allow the user to change the keymap.

2a888f938e Add a prioritization field to the devstat_add_entry() call so that
peripheral drivers can determine where in the devstat(9) list they are
inserted.

This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and
any ports that depend on the devstat code, since the size of the devstat
structure has changed.  The devstat version number has been incremented as
well to reflect the change.

This sorts devices in the devstat list in "more interesting" to "less
interesting" order.  So, for instance, da devices are now more important
than floppy drives, and so will appear before floppy drives in the default
output from systat, iostat, vmstat, etc.

The order of devices is, for now, kept in a central table in devicestat.h.
If individual drivers were able to make a meaningful decision on what
priority they should be at attach time, we could consider splitting the
priority information out into the various drivers.  For now, though, they
have no way of knowing that, so it's easier to put them in an easy to find
table.

Also, move the checkversion() call in vmstat(8) to a more logical place.

Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and
for putting up with the long time it has taken me to commit it.  Bruce did
object somewhat to the central priority table (he would rather the
priorities be distributed in each driver), so his objection is duly noted
here.

sure that this doesn't impact normal floppy units, so I've left this as
an option.

hopefully become a portable driver usable by all architectures.  The api
support files have had to be copied to sys/alpha/include since userland
programs expect to find them in <machine/*.h>.

46f3ff7986 Major ppbus updates from the author.
- ppbus now supports PLIP via the if_plip driver
 - ieee1284 infrastructure added, including parallel-port PnP
 - port microsequencer added, for scripting the sort of port I/O
   that is common with parallel devices without endless calls up and down
   through the driver structure.
 - improved bus ownership behaviour among the ppbus-using drivers.
 - improved I/O chipset feature detection

The vpo driver is now implemented using the microsequencer, leading to
some performance improvements as well as providing an extensive example
of its use.

88a5f0cca7 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.

5c1a1eae83 Fixed error handling:
- Call isa_dmadone() whenever necessary to stop DMA and/or free bounce
  buffers.  Undead DMA corrupted the malloc freelist fairly consistently
  in the following configuration: SLICE kernel, 2 floppy drives, no disk
  in fd0, disk in fd1.
- Don't call fdc_reset() from fd_timeout().  Doing so gave an "extra"
  interrupt which was usually misinterpreted as being for completion
  of the next FDC command; the interrupt for completion of the next
  FDC command was then usually misinterpreted...  There were further
  complications for interrupts latched by the soft-spl mechanism so
  that they were delivered after all the h/w interrupts went away.
  This caused at least wrong head settle delays and may be why the
  FreeBSD floppy driver seems to munch floppies more than most floppy
  drivers.  The reset was unnecessary anyway in cases that didn't have
  the bug described next, since is was repeated a little later for
  the IOTIMEDOUT state.  The state machine has complications to handle
  resets correctly, so just use it.
- Don't call retrier() from fd_timeout().  The IOTIMEDOUT state needs
  to be processed next, and it isn't valid to set to that state if
  retrier() has aborted the current transfer.  Doing so caused null
  pointer panics after the previous bug was fixed.

Improved error handling:
- If an i/o is aborted, arrange to reset in the state machine before
  doing the next i/o.  New fdc flag for this.  This fixes spurious
  warnings and lengthy busy-waiting for the next i/o.
- Split STARTRECAL into RESETCOMPLETE and STARTRECAL and only check
  for the results from reset if we actually reset.  This fixes spurious
  warnings for other paths to STARTRECAL.  [Oops, it may break reset
  handling for motor-off resets.]

Cleanups in fd_timeout():
- Renamed to fd_iotimeout() to make it clearer that it is only used
  for i/o.
- Don't handle the bp == 0 case.  This case can't happen for i/o.
- Don't check for controller-busy.  We know it must be.
- Don't print anything.  retrier() already prints too much for normal
  errors.
- Fudge the state differently so that the state machine advances
  fdc->retry and the status is invalid (perhaps this should fudge a
  valid state like the one for WP).
- Style fixes.

e5d7d24361 Fixed error handling after a seek error that can't happen. When the
controller reports a successful seek, it is very unlikely to report
seeking to a cylinder other than the one requested, but we check for
this, and botched the error handling for the requested_cylinder != 0
case.  This error happened when the bug fixed in rev.1.52 of <sys/buf.h>
caused the head of buffer queue to change to one starting on a different
cylnder - the requested cylinder was found, but it wasn't what we
thought we requested.  The fix is simply to arrange to reset the state
machine.

Corruption of the buffer queue seems to only have been a problem in the
floppy driver.  Other drivers dequeue the head of the queue before doing
physical i/o on it, so the corruption at worse broke the elevator sort
order.  Dequeueing breaks it anyway.

d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers
to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).

- if the sioprobe() for the console failed but another sioprobe()

- it was silly for the console to not be there after printing boot

a4daaa09f2 Implement the spirit but not the letter of Terrys hot-char patch.
The differences Terrys patch and this patch are:
 * Remove a lot of un-needed comments.
 * Don't put l_hotchar at the front of stuct linesw, there is no need to.
 * Use the #defines for the hotchar in the SLIP and PPP line disciplines

5883bcc9d2 Don't (conditionally) override the kernel's min() and max() functions
with macros.  This breaks if the functions are replaced by macros with
unsuitable semantics.   Define a MAX() macro unconditionally instead.
max() is unsuitable since we need a constant expression.  Don't define
MIN() - we never used min().

1d804e7925 Update timer0_prescaler_count before calling hardclock() while timer0
is "acquired".  This fixes a TSC biasing error of about 10 msec when
pcaudio is active.

Update `time' before calling hardclock() when timer0 is being released.
This is not known to be important.

Added some delays in writertc().  Efficiency is not critical here, unlike
in rtcin(), and we already use conservative delays there.

Don't touch the hardware when machdep.i8254_freq is being changed but
the maximum count wouldn't change.  This fixes jitter of up to 10 msec
for most small adjustments to machdep.i8254_freq.  When the maximum
count needs to change, the hardware should be adjusted more carefully.

8a69c85a7e 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.

1ee1681798 - Move the mouse cursor to the center of the screen after video
mode switch in ioctl.
Possibly related to PR: kern/4271

- A kludge: initialize scp->xpixel and ypixel even in the text mode.
If the console enters the `unknown' graphics mode via the ioctl KDSETMODE
(KD_GRAPHICS), these fields are not set (because syscons cannot know
the correct values), but set_mouse_pos() need to refer to these field
to adjust the mouse position.

- Turn off MOUSE_VISIBLE when switching video mode by ioctl.

- another new option: SC_MOUSE_CHAR
Define the first character code of four consecutive codes to be used for
the mouse cursor.  Default codes are 0xd0 through 0xd3.  Beware that
if you decide to use any codes outside the range of 0xc0-0xdf,
the mouse cursor may not look good, because of the way VGA displays
characters in 9-dot-wide character cells.
Requested by several people.

(This patch was tested by a person who recently reported, in the -current
ML, a page fault problem in the kernel (draw_mouse_iamge()) after
X server shutdown. The patch cured his problem.)

is defined. You may still have the reboot key defined in the keymap and
it won't cause error when the keymap is loaded, but it will be quietly
treated as nop.

a3bd3dac25 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).

c6d1bed112 - 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.

10974dbd20 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.
