a021db1639 - If a PCCARD serial device is removed from the system, let the serial
driver 'break out' of the infinite loop waiting for a response from
  it.  This is a bad thing, but no worse than having the kernel hang.

a4daaa09f2 Implement the spirit but not the letter of Terrys hot-char patch.
The differences Terrys patch and this patch are:
 * Remove a lot of un-needed comments.
 * Don't put l_hotchar at the front of stuct linesw, there is no need to.
 * Use the #defines for the hotchar in the SLIP and PPP line disciplines

5883bcc9d2 Don't (conditionally) override the kernel's min() and max() functions
with macros.  This breaks if the functions are replaced by macros with
unsuitable semantics.   Define a MAX() macro unconditionally instead.
max() is unsuitable since we need a constant expression.  Don't define
MIN() - we never used min().

1d804e7925 Update timer0_prescaler_count before calling hardclock() while timer0
is "acquired".  This fixes a TSC biasing error of about 10 msec when
pcaudio is active.

Update `time' before calling hardclock() when timer0 is being released.
This is not known to be important.

Added some delays in writertc().  Efficiency is not critical here, unlike
in rtcin(), and we already use conservative delays there.

Don't touch the hardware when machdep.i8254_freq is being changed but
the maximum count wouldn't change.  This fixes jitter of up to 10 msec
for most small adjustments to machdep.i8254_freq.  When the maximum
count needs to change, the hardware should be adjusted more carefully.

8a69c85a7e Add support for VESA mode 0x102 (800x600x4) in syscons. You can activate
this using option "-b" to the boot blocks.  It is smartest to compile
a font into your kernel (See LINT), but not mandatory, but apart from
the cursor you will see nothing on the screen until you load a font.

This mode allows XF86_VGA16 to run in 800x600 mode on otherwise unsupported
graphics hardware.

A number of buglets in the cursor handling in syscons may become
visible this way.

1ee1681798 - Move the mouse cursor to the center of the screen after video
mode switch in ioctl.
Possibly related to PR: kern/4271

- A kludge: initialize scp->xpixel and ypixel even in the text mode.
If the console enters the `unknown' graphics mode via the ioctl KDSETMODE
(KD_GRAPHICS), these fields are not set (because syscons cannot know
the correct values), but set_mouse_pos() need to refer to these field
to adjust the mouse position.

- Turn off MOUSE_VISIBLE when switching video mode by ioctl.

- another new option: SC_MOUSE_CHAR
Define the first character code of four consecutive codes to be used for
the mouse cursor.  Default codes are 0xd0 through 0xd3.  Beware that
if you decide to use any codes outside the range of 0xc0-0xdf,
the mouse cursor may not look good, because of the way VGA displays
characters in 9-dot-wide character cells.
Requested by several people.

(This patch was tested by a person who recently reported, in the -current
ML, a page fault problem in the kernel (draw_mouse_iamge()) after
X server shutdown. The patch cured his problem.)

loading font into video memory. This will drastically reduce flicker.

- Make sure that the screen is updated for the low-level console

is introduced and will call scupdate() above.

from the low-level console routines sccngetc() and sccncheckc().
Submitted by: bde (a long time ago)

- Don't try to ring bell and immediately return from do_bell() while
device probe is in progress at boot time; the timeout queue is not
functional yet.
PR: kern/2424

- Stop running the screen saver after panic() is called: check
if `panicstr' is non-NULL during scrn_timer().
PR: kern/5314

- A new option: SC_DISABLE_REBOOT
The reboot key (usually Ctl-Alt-Del) will be ignored if this option
is defined. You may still have the reboot key defined in the keymap and
it won't cause error when the keymap is loaded, but it will be quietly
treated as nop.

dad3b88ae3 In the words of the submitter:
----
I've worked to enhance the connect() patches.

I've just tested this with the Linux JDK appletviewer on an applet
that does a lot of connects, and it works as well as during my
previous tests.

The connect() patch is now a merge between my older patch and the
OpenBSD stuff. It ensures that any async error is returned by
connect() instead of getsockopt(SOL_SOCKET, SO_ERROR) as reasonnable
systems do.

There are also minor patches to implement IPPROTO_TCP for
get/setsocktopt(). These are also tested (with Linux Apache).
----

I would appreciate any feedback regarding these changes, as they'd
be very useful in 2.2.6.

95461b450d 1) Start using a cleaner and more consistant page allocator instead
of the various ad-hoc schemes.
2)	When bringing in UPAGES, the pmap code needs to do another vm_page_lookup.
3)	When appropriate, set the PG_A or PG_M bits a-priori to both avoid some
	processor errata, and to minimize redundant processor updating of page
	tables.
4)	Modify pmap_protect so that it can only remove permissions (as it
	originally supported.)  The additional capability is not needed.
5)	Streamline read-only to read-write page mappings.
6)	For pmap_copy_page, don't enable write mapping for source page.
7)	Correct and clean-up pmap_incore.
8)	Cluster initial kern_exec pagin.
9)	Removal of some minor lint from kern_malloc.
10)	Correct some ioopt code.
11)	Remove some dead code from the MI swapout routine.
12)	Correct vm_object_deallocate (to remove backing_object ref.)
13)	Fix dead object handling, that had problems under heavy memory load.
14)	Add minor vm_page_lookup improvements.
15)	Some pages are not in objects, and make sure that the vm_page.c can
	properly support such pages.
16)	Add some more page deficit handling.
17)	Some minor code readability improvements.

eaf13dd73a Change the busy page mgmt, so that when pages are freed, they
MUST be PG_BUSY.  It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed.  The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use.  There were some minor problems
with the collapse code, and this plugs those subtile "holes."

Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages.  I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise.  For now, we are stuck
with the current morass.

2d8acc0f4a VM level code cleanups.
1)	Start using TSM.
	Struct procs continue to point to upages structure, after being freed.
	Struct vmspace continues to point to pte object and kva space for kstack.
	u_map is now superfluous.
2)	vm_map's don't need to be reference counted.  They always exist either
	in the kernel or in a vmspace.  The vmspaces are managed by reference
	counts.
3)	Remove the "wired" vm_map nonsense.
4)	No need to keep a cache of kernel stack kva's.
5)	Get rid of strange looking ++var, and change to var++.
6)	Change more data structures to use our "zone" allocator.  Added
	struct proc, struct vmspace and struct vnode.  This saves a significant
	amount of kva space and physical memory.  Additionally, this enables
	TSM for the zone managed memory.
7)	Keep ioopt disabled for now.
8)	Remove the now bogus "single use" map concept.
9)	Use generation counts or id's for data structures residing in TSM, where
	it allows us to avoid unneeded restart overhead during traversals, where
	blocking might occur.
10)	Account better for memory deficits, so the pageout daemon will be able
	to make enough memory available (experimental.)
11)	Fix some vnode locking problems. (From Tor, I think.)
12)	Add a check in ufs_lookup, to avoid lots of unneeded calls to bcmp.
	(experimental.)
13)	Significantly shrink, cleanup, and make slightly faster the vm_fault.c
	code.  Use generation counts, get rid of unneded collpase operations,
	and clean up the cluster code.
14)	Make vm_zone more suitable for TSM.

This commit is partially as a result of discussions and contributions from
other people, including DG, Tor Egge, PHK, and probably others that I
have forgotten to attribute (so let me know, if I forgot.)

This is not the infamous, final cleanup of the vnode stuff, but a necessary
step.  Vnode mgmt should be correct, but things might still change, and
there is still some missing stuff (like ioopt, and physical backing of
non-merged cache files, debugging of layering concepts.)

95e5e988e0 Make our v_usecount vnode reference count work identically to the
original BSD code.  The association between the vnode and the vm_object
no longer includes reference counts.  The major difference is that
vm_object's are no longer freed gratuitiously from the vnode, and so
once an object is created for the vnode, it will last as long as the
vnode does.

When a vnode object reference count is incremented, then the underlying
vnode reference count is incremented also.  The two "objects" are now
more intimately related, and so the interactions are now much less
complex.

When vnodes are now normally placed onto the free queue with an object still
attached.  The rundown of the object happens at vnode rundown time, and
happens with exactly the same filesystem semantics of the original VFS
code.  There is absolutely no need for vnode_pager_uncache and other
travesties like that anymore.

A side-effect of these changes is that SMP locking should be much simpler,
the I/O copyin/copyout optimizations work, NFS should be more ponderable,
and further work on layered filesystems should be less frustrating, because
of the totally coherent management of the vnode objects and vnodes.

Please be careful with your system while running this code, but I would
greatly appreciate feedback as soon a reasonably possible.

used, and caused a reference to an uninitialised variable (state).
I think I've fixed it now, but since nothing in the tree seems to use it,
I'm not sure.

e1d6dc656d This patch causes the "calltodo" timer list to be decremented by the amount
of time that the laptop was suspending.  Thus, select() calls that might have
suspended rather than firing  at 1hr + "time suspended" since the timer was
posted.

Adding:

    options  APM_FIXUP_CALLTODO

to the kernel config enables the patch.

[
This patch was slightly modified to use a consistant indent style and
I removed some unused local variables.  After this has been tested a
few weeks we'll make the options the default, so for now I'm now
documenting it in LINT.  Mike can later if he wants.

5c623cb649 Add support for low resolution SMP kernel profiling.
- A nonprofiling version of s_lock (called s_lock_np) is used
    by mcount.

  - When profiling is active, more registers are clobbered in
    seemingly simple assembly routines. This means that some
    callers needed to save/restore extra registers.

  - The stack pointer must have space for a 'fake' return address
    in idle, to avoid stack underflow.

8256655132 After one of my analysis passes to evaluate methods for SMP TLB mgmt, I
noticed some major enhancements available for UP situations.  The number
of UP TLB flushes is decreased much more than significantly with these
changes.  Since a TLB flush appears to cost minimally approx 80 cycles,
this is a "nice" enhancement, equiv to eliminating between 40 and 160
instructions per TLB flush.

Changes include making sure that kernel threads all use the same PTD,
and eliminate unneeded PTD switches at context switch time.

5eaf45f67b I've been using these tweaks to enable the sound driver to talk to the
(mutant) Crystal CSS4236 chip on the Intel PR440FX SMP motherboard.

XXX this uses some rather ugly PnP bootstrap code that is *NOT* compatable
with 'controller pnp0' or *ANY* other PnP devices.  If you use some other
PnP devices, enabling css0 will burn your house down. :-]  The
"simplified" PnP init sequence directly blats your config(8) settings onto
the chip.  I'm pretty sure 'css0' will conflict with 'mss0', this whole
area desperately needs a cleanup.

I have been using the following with some success on the PR440FX:
controller   snd0
device css0  at isa? port 0x534 irq 5 drq 1 flags 0x08 vector adintr
device opl0  at isa? port 0x388
device mpu0  at isa? port 0x330 irq 10 vector mpuintr
