f63115591a Included <sys/cdefs.h> since this file is now using __signed. 
It broke non gnu compilers.

2bad33d88e Implements db_write_bytes() for the sun3. 
(Needed now that kernel text is read-only 8-)

81839ca1f7 The sun3 needs its own version of db_write_bytes() so just 
added #ifndef sun3 around it for now.  This function should
probably be provided by each port (like sun3/db_write.c).

86a2079aef When restarting syscalls, make sure we adjust the PC by the correct amount 
depending on what instruction we used to enter the kernel.  Push the
instruction length into tf_err on entry.

ed993b3930 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.

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.)

ddb6e42460 Actually, don't bother checking p == 0 at all. 1994-11-06 20:30:09 +00:00
mycroft
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.

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().

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.
