0cc808ba0d Merge in Kirk's changes to stop softupdates from hogging all of memory. 1998-05-19 21:45:53 +00:00

9feb272372 1. Add new defs for mins and maxs for the POSIX flavor priorities. They
end up being the same, but it doesn't look like you're comparing
apples and oranges.

2. Use need_resched instead of reset_priority.  This isn't right
either, since for example you'll round-robin against equal priority FIFO
processes when lowering the priority of another process,
but this works better and a real fix needs to be in kern_synch and
not out here.

3. This is not a device driver: copyin/copyout the structure.

c3a59be9e0 Remove option for SCHED_FIFO. With this optional, SCHED_FIFO
is the same as RTPRIO_IDLE when it falls through to the default.

99669d2e37 Change to stop a silly panic. This should be understood better.
Change a buffer swizzle trick to a bcopy. It would be nice if the efficient
trick could be used in the future.

a4775d632f Missing parens caused cpu features not to be printed for cyrix >= M2/MX.
Althought the comments say the datasheet doesn't list the device ID
registers on the M2/MX, they seem to be there and quite alive.
(It's interesting to note that the M2/MX calls itself a 686 class cpu but
 is missing a heck of a lot of features, including VME, PGE, PSE, etc)

5f8a4130d8 Added fast IP forwarding code by Matt Thomas <matt@3am-software.com> via
NetBSD, ported to FreeBSD by Pierre Beyssac <pb@fasterix.freenix.org> and
minorly tweaked by me.
This is a standard part of FreeBSD, but must be enabled with:
"sysctl -w net.inet.ip.fastforwarding=1" ...and of course forwarding must
also be enabled. This should probably be modified to use the zone
allocator for speed and space efficiency. The current algorithm also
appears to lose if the number of active paths exceeds IPFLOW_MAX (256),
in which case it wastes lots of time trying to figure out which cache
entry to drop.

1777a04b11 Allow control of the attribute cache timeouts at mount time.
We had run out of bits in the nfs mount flags, I have moved the internal
state flags into a seperate variable.  These are no longer visible via
statfs(), but I don't know of anything that looks at them.

options BROOKTREE_SYSTEM_DEFAULT=BROOKTREE_PAL
in the kernel config file makes the driver's video_open() function
select PAL rather than NTSC. This fixed all the hangs on my
Dual Crystal card when using a PAL video signal.

As a result, you can loose the tsleep (of 2 seconds - now 0.25!!)
which I previously added. (Unless someone else wanted the 0.25
second tsleep).

cf73abacf6 Change simple lock handling to not depend upon having a local apic
available.  The per-cpu variable ss_tpr has been replaced by ss_eflags.
This reduced the number of interrupts sent to the wrong CPU, due to
the cpu having the global lock being inside a critical region.

Remove some unneeded manipulation of tpr register in mplock.s.

Adjust code in mplock.s to be aware of variables on the stack being
destroyed by MPgetlock if GRAB_LOPRIO is defined.

4347025be3 Add forwarding of roundrobin to other cpus. This gives a more regular
update of cpu usage as shown by top when one process is cpu bound
(no system calls) while the system is otherwise idle (except for top).

Don't attempt to switch to the BSP in boot().  If the system was idle when
an interrupt caused a panic, this won't work.  Instead, switch to the BSP
in cpu_reset.

Remove some spurious forward_statclock/forward_hardclock warnings.
