Remove PSL_USERCLR, and add a PSL_USERSTATIC. Change the bit descriptions to

more closely match the 386 manual. (Probably the mnemonics should be changed,
too.)
1995-01-15 00:57:50 +00:00
c7c817b91a
sigreturn() and ptrace() security violations will now trap. Deal with those
...
traps by looking at the instruction stream and the stack to see if it looks
like we're returning to user mode, and if so pop to the hooks in locore.s.
This will fail in the case where a pop %ds or pop %es faults when returning
from a fast interrupt, but this should not be possible.
1995-01-15 00:55:25 +00:00

Enable CR0_AM on 486s. (We already handled the fault.) This would be more

useful if it applied to the kernel.

level protection fault.

Do the eflags security check in a cheaper way. Just check that the privilege

fault later if they are invalid.)

Move the existing frame pointer calculation into a separate helper function.

* Redo most of the message and phase state machines. Multiple pending
...
message outs should now work correctly (including retransmissions).
Multiple messages ins should be more efficient. Missing REQ after
reselection phase should now (correctly) cause a wait with ENREQINIT
set.
* Abstract out the reselection out sequence, and use it directly to
get sense info. (This is somewhat faster than the generic done/sched
sequence.)
* If there are no ACBs available, wait interruptibly for one.
* Leave the interrupt registers alone during message in/out; just
watch for phase change. Don't (incorrectly) reenable interrupts
during data in/out; defer that to aicintr().
* Handle command pointer per SCSI 2 spec.
* Other minor coding improvements.

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.)

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.

* Set the default label after getting the disc size, and fill in the info
for RAW_PART also.
* Change another use of the unit number to a softc pointer.
* Use a dkdevice to hold the label and open partition masks.
* Force the partition offset to 0 for RAW_PART, regardless of the label.
* Nuke MCDPHYS() and MCDREADRAW; they had a silly bug that caused the code
to not work, and they aren't useful anyway.
