The sun3 needs its own version of db_write_bytes() so just

Two trivial optimizations.
1994-11-07 05:09:04 +00:00
d5f99262a9
Since npxdna() and npxsave() are only ever called at spl0 now, we can get rid
...
of all the overhead of frobbing the IDT, and just use a simple flag to tell
npxintr() to ignore interrupts. This allows lots of code reduction.
Also, update some comments and add some DIAGNOSTIC code to detect is these
assumptions ever become wrong.
1994-11-07 03:39:37 +00:00

915336b97c
Approximate the divide by multiplying by 3433/4096. This is faster than

the previous code, and more accurate. Also avoid saving and restoring
registers.
(The multiplication algorithm was generated by GCC.)
1994-11-06 20:33:35 +00:00

Actually, don't bother checking p == 0 at all.
1994-11-06 20:30:09 +00:00
5cf38ebdb4
The case of curproc == 0 `can't happen' unless we're in the idle loop, so
...
allow it to panic by way of a reference to 0 in other cases. Explicitly test
for p == 0 in the specific cases where it's needed, and only calculate pcb if
needed.
1994-11-06 20:28:57 +00:00
9a84611b06
Move the spl0() from the idle loop to the top of cpu_switch(). (This also
...
avoids needing to call spllower() below.) Set curproc immediately after
removing the new process for the run queue, before allowing interrupts again,
for the benefit of schedcpu().
1994-11-06 20:21:29 +00:00
205d425f2f
As pointed out by Bruce, splsoftclock() needs to process pending interrupts
...
when lowering the priority. Do this by simply calling splx(). For the
benefit of NFS (for now), modify splx() to return a value so that
splsoftclock() does. This work is optimized out for every use of splx()
that ignores the value, so it only affects relevant code.
Also, clean up this file a little.

34c4570d61
Only use ssdtosd() when creating, expanding, or copying the LDT. Keep a copy

of the result in the PCB so it can be loaded quickly on context switches.
1994-11-05 03:17:33 +00:00
