3301c800f5 Prevent the TSC from being used on APM machines, we have no idea if
it runs at a constant frequency.  This was less of an issue before,
because the TSC only interpolated in the HZ intervals, but now where
the timecounter is used all the way, this becomes much more visible.

Nit: Fix a printf which triggered the bde-filter.

7ec73f6417 Replace TOD clock code with more systematic approach.
Highlights:
    * Simple model for underlying hardware.
    * Hardware basis for timekeeping can be changed on the fly.
    * Only one hardware clock responsible for TOD keeping.
    * Provides a real nanotime() function.
    * Time granularity: .232E-18 seconds.
    * Frequency granularity:  .238E-12 s/s
    * Frequency adjustment is continuous in time.
    * Less overhead for frequency adjustment.
    * Improves xntpd performance.

a021db1639 - If a PCCARD serial device is removed from the system, let the serial
driver 'break out' of the infinite loop waiting for a response from

5883bcc9d2 Don't (conditionally) override the kernel's min() and max() functions

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.)

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

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.

38c6184fd5 Reject unreasonable values passed to CONS_HISTORY ioctl. It did not
check the value and caused kernel panic when a large value was given.

- Move the configuration option SC_HISTORY_SIZE from syscons.h to
syscons.c.
- Define the maximum total number of history lines of all consoles.
It is SC_HISTORY_SIZE*MAXCONS or 1000*MAXCONS; whichever is larger.
CONS_HISTORY will allow the user to set the history size up to
SC_HISTORY_SIZE unconditionally (or the current height of the console
if it is larger than SC_HISTORY_SIZE). If the user requests a larger
buffer, it will be granted only if the total number of all allocated
history lines and the requested number of lines won't exceed the maximum.
- Don't free the previous history buffer and leave the history buffer
pointer holding a invalid pointer. Set the pointer to NULL first, then
free the buffer.

modems...  vendor id's for sio capabile cards welcomed...

document new option EXTRA_SIO that will increase sio's internal data
structures to support X more serial ports...  these are used by the
PnP part of sio for attaching...  If you don't have it specified, it
will default to 2...  This is defaulted to 0 if you don't have PnP
compiled into your kernel...

also document that if you set the PnP flags (pnp x flags y) to 0x1 that
the modem will be refused to be recognized by the sio driver... this
is for people that want the traditional isa driver to probe and attach
the modem... (for keeping legacy sio numbering)

size in terms of lines (instead of bytes).  When changing video mode
in ioctl SW_XXX commands, syscons checks scp->history_size and
allocate a history buffer at least as large as the new screen size.
(This was unnecessary before, because HISTORY_SIZE was as large as 100
lines and this is bigger than the maximum screen size: 60 lines).

870521063a 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.

ac4c944d67 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.

a2fc20d086 A fix/work-around for ThinkPad 535.
Add a new configuration flag, KBD_NORESET (0x20) to tell scprobe() not
to reset the keyboard.

IBM ThinkPad 535 has the `Fn' key with which the user can perform
certain functions in conjunction with other keys. For example, `Fn' +
PageUP/PageDOWN adjust speaker volume, `Fn' + Home/End change
brightness of LCD screen. It can also be used to suspend the system.

It appears that these functions are implemented at the keyboard level
or the keyboard controller level and totally independent from BIOS or
OS.  But, if the keyboard is reset (as is done in scprobe()), they
become unavailable.  (There are other laptops which have similar
functions associated with the `Fn' key. But, they aren't affected by
keyboard reset.)

ThinkPad 535 doesn't have switches or buttons to adjust brightness and
volume, or to put the system into the suspend mode. Therefore, it is
essential to preserve these `Fn' key functions in FreeBSD. The new
flag make scprobe() skip keyboard reset.

If this flag is not set, scprobe() behaves in the same say as before.

(If we only knew a way to detect ThinkPad 535, we could skip keyboard
reset automatically, but...)

124ff4169d 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.)

3ef626ecd5 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.

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)

sequences.  But only VGA can change the border color and set the
cursor type to destructive (CHAR_CURSOR) in the current syscons.

d75a8fdbb1 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.

31774f6d83 Interim patch/kludge for keyboard lock-up when `kbdcontrol' tries to
change typematic rate, or the X server (XFree86 or Accelerated X)
starts up.

So far, there have been two independent reports from Dell Latitude XPi
notebook/laptop owners. The Latitude seems to be the only system which
suffers from this problem.  (I don't know the problem is with the
entire Latitude line or with only some Latitude models) No problem
report has been heard about other systems (I certainly cannot
reproduce the problem in my -current and 2.2 systems).

In 3.0-CURRENT, 2.2-RELEASE and 2.2-GAMMA-970310, when programming the
keyboard LED/repeat-rate, `set_keyboard()' in `syscons' tells the
keyboard controller not to generate keyboard interrupt (IRQ1) and then
enable tty interrupts, expecting the keyboard interrupt doesn't occur.

It appears that somehow Latitude's keyboard controller still generates
the keyboard interrupt thereafter, and `set_keyboard()' doesn't see
the return code from the keyboard because it is consumed by the
keyboard interrupt handler.

The patch entirely disables tty interrupts while setting LED and
typematic rate in `set_keyboard()', making the routine behave more
like the previous versions of `syscons' (versions in 2.1.X and
2.2-ALPHA, -BETA, and some -GAMMAs). The reporter said this patch
eliminated the problem.

(I also found another typo/bug, but the reporter and I found that it
wasn't the cause of the problem...)

This should go into RELENG_2_2.

49a116737e Estimate an initial overhead of 0 usec instead of 20 usec in DELAY().
I have code to calibrate the overhead fairly accurately, but there
is little point in using it since it is most accurate on machines
where an estimate of 0 works well.  On slow machines, the accuracy
of DELAY() has a large variance since it is limited by the resolution
of getit() even if the initial delay is calibrated perfectly.

Use fixed point and long longs to speed up scaling in DELAY().
The old method slowed down a lot when the frequency became variable.
Assume the default frequency for short delays so that the fixed
point calculation can be exact.

Fast scaling is only important for small delays.  Scaling is done
after looking at the counter and outside the loop, so it doesn't
decrease accuracy or resolution provided it completes before the
delay is up.  The comment in the code is still confused about this.

- don't uselessly initialize the fifo "DMA" bit at attach time.
- initialize the fifo "DMA" bit at open time.  Without this, the device
  interrupts for every character received, reducing input performance
  to that of an 8250.
- don't uselessly initialize the fifo trigger level to 8 (scaled to
  256) at attach time.
- don't scale the fifo trigger level to 512 bytes.  The driver's pseudo-
  dma buffer has size 256, so it can't handle bursts of size 512 or 256.
  It should be able to handle the second lowest ftl (2 scaled to 64).
- don't reset the fifos in siostop().  Reset triggers a hardware bug
  involving wedging of the output interrupt bit  This workaround
  unfortunately requires ESP support to be configured.

page 0 is apparently mapped r/w then, and 0->status contains suitable
garbage.  However, when there is a serial console, scinit() is first
called from scattach() when the page tables are completely initialized,
so the NULL pointer causes a panic.

6bed7e5140 Guard against the i8254 timer being uninitialzed if DELAY() is
called early for console i/o.  The timer is usually in BIOS mode
if it isn't explicitly initialized.  Then it counts twice as fast
and has a max count of 65535 instead of 11932.  The larger count
tended to cause infinite loops for delays of > 20 us.  Such delays
are rare.  For syscons and kbdio, DELAY() is only called early
enough to matter for ddb input after booting with -d, and the delay
is too small to matter (and too small to be correct) except in the
PC98 case.  For pcvt, DELAY() is not used for small delays (pcvt
uses its own broken routine instead of the standard broken one),
but some versions call DELAY() with a large arg when they unnecessarily
initialize the keyboard for doing console output.  The problem is
more serious for pcvt because there is always some early console
output.

Guard against the i8254 timer being partially or incorrectly
initialized.  This would have prevented the endless loop.

Should be in 2.2.

1f9d9075e4 Alot of fixes from kazu:
1. All the suggestions earlier made by Bruce: renaming some symbols,
stricter error checking, removing redundant code, etc.

2. The `psm' driver preserves the default counter resolution and
report rate, whatever they are after reset. (Based on reports and
suggestion from Nate and Rob Bolin).

3. The `psm' driver now does not check the so-called sync. bit in the
first byte of the data packet by default, so that the tapping feature
of ALPUS GlidePoint works (based on reports from Louis Mamakos). I
tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found
no problem; tapping worked. It appears ALPUS produces several models
of GlidePoint. I hope the other models are OK too.

The check code can still be activated by defining the PSM_CHECKSYNC
option in the config file. (The bit checking slightly reduces, if not
completely eliminates, weird mouse behavior cased by unsynchronized
mouse data packets. It also helps us to detect if the mouse interrupt
can ever be lost. But, well, if there are devices which cannot be
supported this way...)

4. The `psm' driver does not include the protocol emulation code by
default. The code can still be compiled in if the PSM_EMULATION option
is specified in the config file. Louis Mamakos suggests the emulation
code is putting too much in the kernel, and `moused' works well.
I will think about this later and decide if the entire emulation
code should be removed.

5. And, of course, the fix in `scprobe()' from Bruce to cure the
UserConfig problem. My code in `kbdio.c' is slightly different from
his patch, but has the same effect. There still is a possibility that
`scprobe()' gets confused, if, for whatever reasons, the user holds
down a key for very long time during the boot process. But we cannot
cope with everything, can we?

66e7fce7ac 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.

c070783c4b Changed mouse functionality a bit, now the pointer disappears if
there is keyboard input.
The mousepointer is shown again immediately if moved.

Also a function pointer used to install a userwritten extra
ioctl handler (sc_user_ioctl). This way its is possible to
install user defined videomodes etc etc. No further changes
should be in the kernel.

92d0aa20dc Work around UMC8669F and Startech UART bugs by not writing to the
divisor latch registers if the registers wouldn't change.

Use the default console cfcr setting while setting the divisor
latch registers for console i/o.  Input may be messed up by
transiently changing the cfcr.

Use a usual cfcr setting while setting the divisor latch registers
in the probe.  This shouldn't matter, but this is not the place to
test the UART's handling of 5 bit words.

9545a0eaa4 Hack workaround XFree86 switching failure when used with /dev/sysmouse
and xdm, possibly in general.

What was happening was that the server was doing a tcsetattr(.. TCSADRAIN)
on the mouse fd after a write.  Since /dev/sysmouse had a null t_oproc,
the drain failed with EIO.  Somehow this spammed XFree86 (!@&^#%*& binary
release!!), and the driver was left in a bogus state (ie: switch_in_progress
permanently TRUE).

The simplest way out was to implement a dummy scmousestart() routine to
accept any characters from the tty system and toss them into the void.

It would probably be more correct to intercept scwrite()'s to the mouse
device, but that's executed for every single write to the screen.
Supplying a start routine to eat the characters is only executed for the
mouse port during startup/shutdown, so it should be faster.

47382cd1e0 Make syscons replicate a mousesystems mouse on minor 128..
This enables other consumers of the mouse, to get it info via
moused/syscons.
In order to use it run moused (from sysconfig), and then tell
your Xserver that it should use /dev/sysmouse (mknod sysmouse c 12 128)
and it a mousesystems mouse. Everybody will be happy then :)
Remember that moused still needs to know what kind of mouse you
have..

53809eab9c Add option SC_KBD_PROBE_WORKS to syscons driver.
If you define this, it means your keyboard is actually probable using the
brain-dammaged probe routine in syscons, and if the keyboard is NOT found,
then you don't want syscons to activate itself further.

This makes life sane for those of us who use serial consoles most of the
time and want "the right thing" to happen when we plug a keyboard in.

make it more intelligible, improve the partially bogus locking, and
allow for a ``quick re-acquiration'' from a pending release of timer 0
that happened ``recently'', so it was not processed yet by clkintr().

Testing with the high frequency of 20000 Hz (to find problems) only found
the problem that this frequency is too high for slow i386's.

Disable interrupts while setting the timer frequency.  This was unnecessary
before rev.1.57 and forgotten in rev.1.57.  The critical (i8254) interrupts
are disabled in another way at boot time but not in the sysctl to change
the frequency.

7d64a7fe80 Added support for TIOCDCDTIMESTAMP (enable/get timestamp of last DCD rise).
Original version by John Hay.

Simplified timestamp code by reading the time exactly when necessary.
This may slow down the interrupt handler with extra calls to microtime(),
but only in bad configurations - the input fifo should normally be
disabled if timestamps on input are being used, since otherwise the
timestamp won't be precisely associated with any particular input event.
The interrupt handler remains slowed down by one test and branch for
each input (and now DCD change) event - avoiding this is not practical
yet.

The simplifications also fixed:
- timestamps for input sometimes being clobbered by output and modem
  status interrupts.
- valid timestamps not being available unless the port is configured with
  vector siointrts.  siointrts no longer exists.
- compiler warnings about siointr* in some configurations.

Simplified timestamp and probe code by depending on recent changes in
microtime() and DELAY() to preserve the interrupt enable flag.

16263f7a8b In getit(), use read_eflags()/write_eflags() to preserve the interrupt
enable flag instead of enable_intr() to restore it to its usual state.
getit() is only called from DELAY() so there is no point in optimising
its speed (this wasn't so clear when it was extern), and using
enable_intr() made it inconvenient to call DELAY() from probes that need
to run with interrupts disabled.

2dafbfcbab Added calibration the i8254 and the i586 clocks agains the RTC at boot
time.  The results are currently ignored unless certain temporary options
are used.

Added sysctls to support reading and writing the clock frequency variables
(not the frequencies themselves).  Writing is supposed to atomically
adjust all related variables.

machdep.c:
Fixed spelling of a function name in a comment so that I can log this
message which should have been with the previous commit.

Initialize `cpu_class' earlier so that it can be used in startrtclock()
instead of in calibrate_cyclecounter() (which no longer exists).

Removed range checking of `cpu'.  It is always initialized to CPU_XXX
so it is less likely to be out of bounds than most variables.

clock.h:
Removed I586_CYCLECTR().  Use rdtsc() instead.

clock.c:
TIMER_FREQ is now a variable timer_freq that defaults to the old value of
TIMER_FREQ.  #define'ing TIMER_FREQ should still work and may be the best
way of setting the frequency.

Calibration involves counting cycles while watching the RTC for one second.
This gives values correct to within (a few ppm) + (the innaccuracy of the
RTC) on my systems.
