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.
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.
actually faster (more than 20% faster for zeroing 1 MB at boot time).
This fixes pessimized copying and zeroing on K6's and perhaps on other
CPUs that are misclassified as i586's.

- 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.)
Don't touch/update the screen while manipulating font data.

- Set up VGA in alphanumeric mode rather than graphics mode when
loading font into video memory. This will drastically reduce flicker.

- Set up scp->font_size properly during video mode switch caused by
ioctl.
separate routine: scupdate() called from scrn_timer().
- Make sure that the screen is updated for the low-level console
routines sccngetc() and sccncheckc(). A new routine, sccnupdate(),
is introduced and will call scupdate() above.

- Don't try to ring bell and immediately return from do_bell() while
device probe is in progress at boot time; the timeout queue is not
functional yet.

- A new option: SC_DISABLE_REBOOT
The reboot key (usually Ctl-Alt-Del) will be ignored if this option
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.

prematurely when there was a hole (for a cdrom or an unused
interface) in the sequence of wd drives. This caused non-free
wd units to be probed as atapi drives. There was no problem
provided the atapi probe failed correctly.
All known versions of this drive (firmware 21.* and 23.*) will lock up
if presented with a read/write request of > 64 blocks. In the presence
of such a unit, I/O requests of > 64 blocks are fragmented to avoid
this.
This introduce an xxxFS_BOOT for each of the rootable filesystems.
(Presently not required, but encouraged to allow a smooth move of option *FS
to opt_dontuse.h later.)
LFS is temporarily disabled, and will be re-enabled tomorrow.
so that existing programs which were compiled before the introduction
of the new mouse code and use these ioctls will run unmodified.

This is Junichi's v1.0 driver.
NOTE: Major device numbers have been changed to avoid conflict with other
FreeBSD 3.0 devices. The new numbers should be considered "official."
This driver is still considered "beta" quality, although we have been
playing with it. Please submit bugs to junichi and myself.
