christos 2859b1c634 Rework streams emulation so that it does not rely on non portable hacks.
We keep streams state in so->so_ptcb; this field is unused in all the kernel.
Fix poll(2) timeout computation; add hrtsys and waitsys syscalls.
1994-11-18 02:53:37 +00:00
christos 70e6f7edb8 Don't VOP_UNLOCK the vnode on a cloning operation. vput() will do it for
us.

gwr 2bad33d88e Implements db_write_bytes() for the sun3.
(Needed now that kernel text is read-only 8-)
1994-11-17 05:08:55 +00:00
gwr 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).

mycroft cfae52f542 It's legitimate, if foolish, to mask SIGCONT. 1994-11-07 05:57:28 +00:00
mycroft 297c06de67 Comment previous change. 1994-11-07 05:32:50 +00:00
mycroft 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.
1994-11-07 05:26:08 +00:00
mycroft ed993b3930 Two trivial optimizations. 1994-11-07 05:09:04 +00:00
mycroft 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
mycroft 5133a6cfd7 Only save the FPU state if somebody else needs the FPU, or when forking. 1994-11-06 23:43:17 +00:00
mycroft f3ef31e4aa Oops; forgot to adjust stack offset. 1994-11-06 22:05:08 +00:00
mycroft 37863af7bb Forgot two underscores. 1994-11-06 21:51:47 +00:00
cgd d4510670f1 fix for bug 559, as reported by Jason Thorpe. (fix by me) 1994-11-06 21:49:08 +00:00
mycroft 58b3010e87 Use %eax slightly more effectively in cpu_switch(). 1994-11-06 20:51:46 +00:00
mycroft 2f38797073 Trivial changes to make the code more consistent. 1994-11-06 20:39:50 +00:00
mycroft 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
mycroft 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.
1994-11-06 20:28:57 +00:00
mycroft 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
mycroft 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.

mycroft c2191a2ad0 Fully prototype ssdtosd() and sdtossd(). 1994-11-05 03:20:36 +00:00
mycroft 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
mycroft 867ac5e15f Add sdtossd() by HOSOKAWA Tatsumi, and a C version of ssdtosd() by me. 1994-11-05 02:47:02 +00:00
mycroft 600aa2c5f8 Trivial optimizations. Also, make sure we get the overflow correct if
called at spl >= clock.
1994-11-05 02:16:26 +00:00
mycroft 2a9b6f7959 Fix stupid bug in last change. 1994-11-04 23:30:15 +00:00
mycroft 4ec6774e12 Add a simplified version of wdcommand() that can be used in some cases.
Avoid needing a wd_softc inside wdprobe().

mycroft f8183b2d0e Make a wrapper match function to check the bus and device numbers, rather
than insisting that every driver do it.
1994-11-04 09:42:18 +00:00
mycroft 9af4fee97d Use kvtop() rather than address arithmetic in a couple of places. 1994-11-04 08:55:53 +00:00
