necessary to call it when the tty layer's output state has not been
changed, but siostop() sometimes changes the TS_BUSY state and then
calls comstart() mainly for its side effect of calling ttwwakeup().
need to do it directly, since ttwwakeup() is always called just before
returning from rpstart(). The brokenness was waking up the wrong address
after clearing TS_SO_OLOWAT. It's not clear how processes waiting for
output to drain below low water ever got woken up.
Found by: when I fixed longstanding warts in output watermark
handling, this was the only driver that knew too much
(anything) about the watermarks
used, and caused a reference to an uninitialised variable (state).
I think I've fixed it now, but since nothing in the tree seems to use it,
I'm not sure.

suspended rather than firing at 1hr + "time suspended" since the timer was
posted.
Adding:
options APM_FIXUP_CALLTODO
to the kernel config enables the patch.

This patch was slightly modified to use a consistant indent style and
I removed some unused local variables. After this has been tested a
few weeks we'll make the options the default, so for now I'm now
documenting it in LINT. Mike can later if he wants.

- A nonprofiling version of s_lock (called s_lock_np) is used
by mcount.
- When profiling is active, more registers are clobbered in
seemingly simple assembly routines. This means that some
callers needed to save/restore extra registers.
- The stack pointer must have space for a 'fake' return address
in idle, to avoid stack underflow.
- emulate Linux IP_HDRINCL behaviour in sendto(): byte order fixed
Note that we do an extra getsockopt() on every sendto()
to check if the option is set because we don't keep state
in the emulator code. Is there a better way to implement
this?
- correct a bug (value of "name" not passed) with
getsockopt()

noticed some major enhancements available for UP situations. The number
of UP TLB flushes is decreased much more than significantly with these
changes. Since a TLB flush appears to cost minimally approx 80 cycles,
this is a "nice" enhancement, equiv to eliminating between 40 and 160
instructions per TLB flush.
Changes include making sure that kernel threads all use the same PTD,
and eliminate unneeded PTD switches at context switch time.
(mutant) Crystal CSS4236 chip on the Intel PR440FX SMP motherboard.
XXX this uses some rather ugly PnP bootstrap code that is *NOT* compatable
with 'controller pnp0' or *ANY* other PnP devices. If you use some other
PnP devices, enabling css0 will burn your house down. :-] The
"simplified" PnP init sequence directly blats your config(8) settings onto
the chip. I'm pretty sure 'css0' will conflict with 'mss0', this whole
area desperately needs a cleanup.
I have been using the following with some success on the PR440FX:
controller snd0
device css0 at isa? port 0x534 irq 5 drq 1 flags 0x08 vector adintr
device opl0 at isa? port 0x388
device mpu0 at isa? port 0x330 irq 10 vector mpuintr
Wrappered and enabled by the define BETTER_CLOCK (on by default in smpyests.h)
apic_vector.s also contains a small change I (smp) made to eliminate
the double level INT problem. It seems stable, but I haven't the tools
in place to prove it fixes the problem.

- 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.
so the filenames can be displayed and selected in full beauty. If RR
is present, the match is now case-sensitive, if RR is missing, the
match is case-insensitive (as it used to be before).
