1.1.5.1, and oversaw this thang.

e754e0f30f Fixed bug that somehow made it into here: the ifp must be stored in the
mbuf header for received packets. Minor performance optimizations. Removed
#ifdef MULTICAST's as this isn't optional in our kernel.

bc8cb7d0b4 Avoid a division by zero if the actual sector size isn't known during the
device announcement; assume a sector size of 512 instead (likely to be
right at all).
This case happens when booting with a removable disk device attached
(e.g. an MOD), but no medium inserted.

ad63b51399 2 11th-hour fixes from Ugen (not Uben, sorry!) J.S.Antsilevich.
I think it's time for Ugen to get a freefall account, just so I can
direct mail at him directly and let him drop off patches for us here.  Ugen?
Done!

98020fdd6c Added a kernel variable, "dodump" defaulting to zero, which disables dumps.
Somebody should make a mib variable for it.
Just now it is pointless to dump the kernel, since we have nothing which
can read the dump.
Furthermore is should never be the default to dump.
	options	DODUMP
will enable dumps.

2fe6e4d71e Added support for starting the experimental "vmdaemon" system process.
Enabled via REL2_1.

Added support for doing object collapses "on the fly". Enabled via REL2_1a.

Improved object collapses so that they can happen in more cases. Improved
sensing of modified pages to fix an apparant race condition and improve
clustered pageout opportunities. Fixed an "oops" with not restarting page
scan after a potential block in vm_pageout_clean() (not doing this can result
in strange behavior in some cases).

2c305bdb3c Nuke the losing version of microtime. The assembler version now works
for all reasonable HZ's.  HZ > 1000 doesn't work because of sloppy
conversions in hzto() (division by (tick / 1000) == 0).  This was
fixed in 1.1.5.

Eliminate some extern declarations by including the appropriate header
files that now contain appropriate declarations.

5eb4d8cfd4 Abort writes if a signal is received (don't ignore the value returned by
tsleep()).  Try `dd if=/dev/zero of=/dev/pcaudio bs=640k count=1'.  The
write takes a few hundred seconds to drain, and if it is killed by a
signal, it still takes a few hundred seconds to drain and all of those
seconds are spent busy-waiting.

Clean up includes and declarations.  Remove bogus casts of args to
timeout functions.

2f31d30b01 Work around microtime() enabling interrupts. 1994-11-06 00:23:45 +00:00
Bruce Evans
a3b33372b9 Maintain a new variable `timer0_overflow_threshold' so that microtime()
doesn't have to calculate it every call.

Rename `timer0_prescale' to `timer0_prescaler_count' and maintain it
correctly.  Previously we lost a few 8253 cycles for every "prescaled"
clock interrupt, and the lossage grows rapidly at 16 KHz.  Now we
only lose a few cycles for every standard clock interrupt.

Rename `*_divisor' to `*_max_count'.

Do the calculation of TIMER_DIV(rate) only once instead of 3 times each
time the rate is changed.

Don't allow preposterously large interrupt rates.  Bug fixes elsewhere
should allow the system to survive rates that saturate the system, however.

Clean up declarations.

Include <machine/clock.h> to check our own declarations.

ae406484f0 Fix a bug introduced between 1.1 and 1.1.5. Loading the time was moved
outside the critical region.

Make it work with 2.0.  It wasn't designed to be called at splclock().

Make it work with prescaling.  The overflow threshold was bogus.

Make it work for any HZ.  Side effect of fixing prescaling.

Speed it up.  Allocate registers better.  Reduce multiplication and
division to multiplication and a shift.  Speed is now 5-6 usec on a
486DX/33, was about 3 usec more.

Optimize for the non-pentium case.  The pentium code got moved around
a bit and hasn't been tested.

Change #include's to 2.0 style.

c342b9faa3 Disable the direct call from hardclock() to softclock(). Support
for it is incomplete and buggy.  There is no problem unless Xintr0()
is reentered or should be reentered, but high clock interrupt
frequencies for pcaudio cause Xintr0() to be reentered (or clock
ticks to be lost when Xintr0() should have been reentered but
wasn't), and we lose little by delaying the call to softclock().

Move declarations related to the clock driver to clock.h.

Move declarations related to the npx driver to npx.h.

Clean up the remaining declarations.

c4a7b7e10c From tim@cs.city.ac.uk (Tim Wilkinson):
Find enclosed a short bugfix to get the union filesystem up and running
in FreeBSD-current.  We don't think we've got all the problems yet but
these fixes sort out the major ones (which mostly concert bad locking
of vnodes), no doubt we'll post others as necessary.  Known problems
include the inability of the umount command (not the system call) to unmount
unions in certain circumstances (this is due the way "realpath" works),
and the failure of direntries to always get all available files in
unioned subdirectories.  We are, as they say, working on it.

fb21f2fe90 Backed out mbuf performance improvement. mbufs are allocated with various
different types, and with the 'local cache', what is freed isn't necessarily
what was originally malloced. This screws malloc's statistics and type
allocation limits, resulting eventually in a deadlock when one of the
limits is bogusly reached. Recent performance tests on a Pentium machine
indicate no improvement with this optimization anyway (this is something
to be looked at further).
