Check that a received packet isn't longer than MCLBYTES. This will
sometimes happen if a cable is plugged into or removed from a live
system.
Try to cater better for early receive interrupts.
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.

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.
- use a more accurate and more efficient method of compensating for
overheads. The old method counted too much time against leaf
functions.
- normally use the Pentium timestamp counter if available.
On Pentiums, the times are now accurate to within a couple of cpu
clock cycles per function call in the (unlikely) event that there
are no cache misses in or caused by the profiling code.
- optionally use an arbitrary Pentium event counter if available.
- optionally regress to using the i8254 counter.
- scaled the i8254 counter by a factor of 128. Now the i8254 counters
overflow slightly faster than the TSC counters for a 150MHz Pentium :-)
(after about 16 seconds). This is to avoid fractional overheads.
files.i386:
permon.c temporarily has to be classified as a profiling-routine
because a couple of functions in it may be called from profiling code.
options.i386:
- I586_CTR_GUPROF is currently unused (oops).
- I586_PMC_GUPROF should be something like 0x70000 to enable (but not
use unless prof_machdep.c is changed) support for Pentium event
counters. 7 is a control mode and the counter number 0 is somewhere
in the 0000 bits (see perfmon.h for the encoding).
profile.h:
- added declarations.
- cleaned up separation of user mode declarations.
prof_machdep.c:
Mostly clock-select changes. The default clock can be changed by
editing kmem. There should be a sysctl for this.
subr_prof.c:
- added copyright.
- calibrate overheads for the new method.
- documented new method.
- fixed races and and machine dependencies in start/stop code.
mcount.c:
Use the new overhead compensation method.
gmon.h:
- changed GPROF4 counter type from unsigned to int. Oops, this should
be machine-dependent and/or int32_t.
- reorganized overhead counters.

controllers, it is an error to issue a command before the keyboard
has had time to reply to the previous command. Setting the LEDs
involves issueing 2 commands, so it never worked on these keyboards.
Fixed resetting of keyboard. It is possible for unprocessed
scancodes to be present when the reset routine is called. This
usually occurs after switching from one console driver to another
in userconfig. pcvt and syscons attempt to flush any stale scancodes,
but sometimes fail to do so because keyboard and/or keyboard
controller takes a long time to send the scancodes after reset
(scancodes are apparently not flushed by reset!). syscons handles
this later by not checking for errors at strategic places, but pcvt
was confused.
Use an impossible initial and failure mode setting for the LEDs
so that the LEDs always get set if they are possibly out of sync.
Added missing spltty() in update_led().
(1) Merged i386/i386/sb.h, deleted pc98/pc98/sb.h.
(2) pc98/conf/GENERIC8 looks more like i386/conf/GENERIC now.

pc98/i386/machdep.c
pc98/pc98/pc98_machdep.c
pc98/pc98/pc98_machdep.h
(5) Support new board "C-NET(98)":
pc98/pc98/if_ed98.h
pc98/pc98/if_ed.c
(6) Make sure FPU is recognized for non-Intel CPUs:
pc98/pc98/npx.c

I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine. This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in. It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.
PCI and EISA front ends will show up as soon as I get my hands on
the cards. There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)
Thanks to AdvanSys for releasing this code under a suitable copyright.

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.
Removed a stale devfs comment.
- don't include <sys/ioctl.h> in any header. Include <sys/ioccom.h>
instead. This was already done in 4.4Lite for the most important
ioctl headers. Header spam currently increases kernel build
times by 10-20%. There are more than 30000 #includes (not counting
duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
almost self-sufficient (some ioctl headers still need structs from
elsewhere).
- uniformized idempotency ifdefs. Copied the style in the 4.4Lite
ioctl headers.
It is needed for implementation details but very little of it is
needed for the interface. Include it in the few places that didn't
already include it.
Include <sys/ioccom.h> in <sys/disklabel.h> (as already in
<sys/diskslice.h>) so that all the disk-related headers are almost
self-sufficient.
instead of 0 if there is no input.
pcvt_drv.c:
Partially fixed pccncheckc(). It returned a boolean value instead of
the character that it fetches from the input fifo (if any). I think
it still discards characters after the first for multi-char input.
instead of 0 if there is no input.
syscons.c:
Added missing spl locking in sccncheckc(). Return the same value as
sccngetc() would. It is wrong for sccngetc() to return non-ASCII, but
stripping the non-ASCII bits doesn't help.
still being used just to support printing of the device name in the
probe. Restored the method used in rev.1.6 and changed it to print
the same strings as the previous revision.
