f9c9bbc054 If vm86 services are available, use these to perform the APM BIOS
probe and intialisation.  This will ultimately remove the grubby (but
functional) hack that copies a real-mode function into low memory
early in locore.s.

ba98833992 ".. x11amp appears to be calling shmctl(id, IPC_RMID, 0) and the emulation
layer does not like the null shmid_ds buffer pointer.  The emulation layer
returned an error without ever calling FreeBSD's shmctl, so the segments
were not being deleted when the reference count went to zero."

cd55b8f46c Converted the ICU-level interrupt tests (3, 5 and 8) in sioprobe() into
a test of the irq number, and made failure of this test non-fatal.
Removed related unused complications for the APIC_IO case.  Removed the
no-test3 flag.

Deverbosified the failure messages for the other tests.  Removed the
per-port verbose flag - just use the general verbose flag.

e796e00de3 Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.
Clean up (or if antipodic: down) some of the msgbuf stuff.

Use an inline function rather than a macro for timecounter delta.

Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.

Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()

This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

WARNING:  Programs which muck about with struct proc in userland
will have to be fixed.

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.

 is missing a heck of a lot of features, including VME, PGE, PSE, etc)

5d183e9691 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  The per-cpu variable ss_tpr has been replaced by ss_eflags.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.

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.

b322fb5d76 Backed out previous commit. It is invalid to call d_ioctl() on
possibly non-open devices, and we don't want to restrict dumping
to swap devices anwyay.  It is especially invalid to call d_ioctl()
in non-process context for panics.  d_psize() can be called on
non-open devices, at least on non-SLICED ones that support d_dump(),
and setdumpdev() has depended on this for a long time although it
is probably wrong, but even d_psize() can't be called in non-process
context - that's why dumpsys() depends on previously computed values
although these values may be stale.  The historical restriction to
devices with dkpart(dev) == SWAP_PART should go away.

3e425b968d Add changes and code to implement a functional DEVFS.
This code will be turned on with the TWO options
DEVFS and SLICE. (see LINT)
Two labels PRE_DEVFS_SLICE and POST_DEVFS_SLICE will deliniate these changes.

/dev will be automatically mounted by init (thanks phk)
on bootup. See /sys/dev/slice/slice.4 for more info.
All code should act the same without these options enabled.

This code does not support the following:
bad144 handling.
Persistance. (My head is still hurting from the last time we discussed this)
ATAPI flopies are not handled by the SLICE code yet.

When this code is running, all major numbers are arbitrary and COULD
be dynamically assigned. (this is not done, for POLA only)
Minor numbers for disk slices ARE arbitray and dynamically assigned.

device. But with devfs, currently, /dev/psm0 is the blocking device
and /dev/npsm0 is the non-blocking one.

DEVFS must stay consistent with the older behaviour.

a117d26a3d More fixes to deal with fonts:
- Set the correct value scp->font_size in init_scp().
- Set scp->font_size to FONT_NONE for VGA_MODEX.

Interim fix for a font problem:
- A kludge to display the correct font on some video cards.
  We should be able to load multiple fonts to the VGA plane #2 and switch
  between fonts by setting the font select register in the VGA sequencer.
  It appears that the current code isn't functioning as expected on
  some VGA cards (I have reports on Millenium and Mach64 cards).  This is
  either a bug in syscons or a hardware compatibility problem ;-<
  This kludge will always load only one font set at a time and always use
  the font page #0 on the plane #2.  It is an interim kludge until
  we find the exact cause and solution.

Small adjustment for mouse cursor handling:
- Turn off the mouse cursor early when changing video modes.

Video mode switch fixes:
- Stop the screen saver when changing video modes.
- Enclose the critical section with a pair of spltty()/splx().
- A kludge to prevent scrn_update() from accessing video memory in less-
  critical sections in video mode change; artificially turn on the
  UNKNOWN_MODE flag.

227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

7ab95d0bab Be less draconian about the TSC if APM is configured, use it for
timecounting if APM-BIOS isn't found.
Be just as draconian about SMP as always, but explain it better.

bef608bd7e Some VM improvements, including elimination of alot of Sig-11
problems.  Tor Egge and others have helped with various VM bugs
lately, but don't blame him -- blame me!!!

pmap.c:
1)	Create an object for kernel page table allocations.  This
	fixes a bogus allocation method previously used for such, by
	grabbing pages from the kernel object, using bogus pindexes.
	(This was a code cleanup, and perhaps a minor system stability
	 issue.)

pmap.c:
2)	Pre-set the modify and accessed bits when prudent.  This will
	decrease bus traffic under certain circumstances.

vfs_bio.c, vfs_cluster.c:
3)	Rather than calculating the beginning virtual byte offset
	multiple times, stick the offset into the buffer header, so
	that the calculated offset can be reused.  (Long long multiplies
	are often expensive, and this is a probably unmeasurable performance
	improvement, and code cleanup.)

vfs_bio.c:
4)	Handle write recursion more intelligently (but not perfectly) so
	that it is less likely to cause a system panic, and is also
	much more robust.

vfs_bio.c:
5)	getblk incorrectly wrote out blocks that are incorrectly sized.
	The problem is fixed, and writes blocks out ONLY when B_DELWRI
	is true.

vfs_bio.c:
6)	Check that already constituted buffers have fully valid pages.  If
	not, then make sure that the B_CACHE bit is not set. (This was
	a major source of Sig-11 type problems.)

vfs_bio.c:
7)	Fix a potential system deadlock due to an incorrectly specified
	sleep priority while waiting for a buffer write operation.  The
	change that I made opens the system up to serious problems, and
	we need to examine the issue of process sleep priorities.

vfs_cluster.c, vfs_bio.c:
8)	Make clustered reads work more correctly (and more completely)
	when buffers are already constituted, but not fully valid.
	(This was another system reliability issue.)

vfs_subr.c, ffs_inode.c:
9)	Create a vtruncbuf function, which is used by filesystems that
	can truncate files.  The vinvalbuf forced a file sync type operation,
	while vtruncbuf only invalidates the buffers past the new end of file,
	and also invalidates the appropriate pages.  (This was a system reliabiliy
	and performance issue.)

10)	Modify FFS to use vtruncbuf.

vm_object.c:
11)	Make the object rundown mechanism for OBJT_VNODE type objects work
	more correctly.  Included in that fix, create pager entries for
	the OBJT_DEAD pager type, so that paging requests that might slip
	in during race conditions are properly handled.  (This was a system
	reliability issue.)

vm_page.c:
12)	Make some of the page validation routines be a little less picky
	about arguments passed to them.  Also, support page invalidation
	change the object generation count so that we handle generation
	counts a little more robustly.

vm_pageout.c:
13)	Further reduce pageout daemon activity when the system doesn't
	need help from it.  There should be no additional performance
	decrease even when the pageout daemon is running.  (This was
	a significant performance issue.)

vnode_pager.c:
14)	Teach the vnode pager to handle race conditions during vnode
	deallocations.

c555a715f5 On SMP systems, initially follow the MP spec with regard to which pin
on the IOAPIC being connected to the 8254 timer interrupt.
Verify that timer interrupts are delivered. If they aren't, attempt
a fallback to mixed mode (i.e. routing the timer interrupt via the 8259 PIC).

d20d60be28 Don't use the standard macros for disabling/enabling interrupt.
On SMP systems, this left the mpintr_lock simplelock locked, causing
further calls to disable_intr to deadlock or panic.

afe4dfa050 Added a null entry for sysmk that is generated by makesyscalls.sh.
Gee, I wish there was a better way to run makesyscalls.sh so that
a make world finds missing things like this. Running it manually
sucks.

7762bc7bdf Fixed breakage of the !SMP case in vm_page_zero_idle() in the
previous commit.  Opportunities to clean pages were often missed,
and leaving of the idle state was sometimes delayed until the next
interrupt (after any that occurred while cleaning).

Fixed an unstaticization, a syntax error and a style bug in the
previous commit.
