7a7386a3e2 Device driver for onboard CS4231 audio controller which is found
on UltraSPARC workstations. The driver is based on OpenBSD's SBus
cs4231 driver and heavily modified to incorporate into sound(4)
infrastructure. Due to the lack of APCDMA documentation, the DMA
code of SBus cs4231 came from OpenBSD's driver.
The driver runs without Giant lock and supports both SBus and EBus
based CS4231 audio controller. Special thanks to marius for providing
feedbacks during the driver writing. His feedback made it possible
to write hiccup free playback code under high system loads.

de4447e1c0 Back out v1.58... We still don't know what is causing the specific
problem I had but it's happening in code that is messing around with
register windows - I'm willing to live with that piece being sensitive
to this and it looks like the other problems we had reported lately
are not fixed by using -O instead of -O2.

e47bf36158 Back out v1.49. Recent findings suggest sparc64 may not be ready for
-O2 on kernel compiles after all.  While working on adding a KASSERT
to sparc64/sparc64/rwindow.c I found that it was "position sensitive",
putting it above a call to flushw() instead of below caused corruption
of processes on the system.  jake and jhb have both confirmed there is
no obvious explanation for that.  The exact same kernel code does not
have the process corruption problem if compiled with -O instead of -O2.
There have been signs of similar issues floated on the sparc64@ mailing
list, lets see if this helps make them go away.

Note this isn't an optimal fix as far as the file format goes, if this
disgusts too many people I'll fix it the right way.  Since compiling
with something other than -O is a known problem this format would prevent
a change to the default causing grief.  And this may also help motivate
finding out what the compiler is doing wrong so we can shift back to
using -O2. :-)

My turn for the pointy hat...  One of the florescent ones...

f6bde1fd05 Add a new API for allocating unit number (-like) resources.
Allocation is always lowest free unit number.

A mixed range/bitmap strategy for maximum memory efficiency.  In
the typical case where no unit numbers are freed total memory usage
is 56 bytes on i386.

malloc is called M_WAITOK but no locking is provided (yet).  A bit of
experience will be necessary to determine the best strategy.  Hopefully
a "caller provides locking" strategy can be maintained, but that may
require use of M_NOWAIT allocation and failure handling.

A userland test driver is included.

2169193596 Converge towards i386. I originally resisted creating <machine/pc/bios.h>
because it was mostly irrelevant - except for the silly BIOS_PADDRTOVADDR
etc macros.  Along the way of working around this, I missed a few things.

* Make syscons properly inherit the bios capslock/shiftlock/etc state like
  i386 does.  Note that we cannot inherit the bios key repeat rate because
  that requires a bios call (which is impossible for us).
* Give syscons the ability to beep on amd64.  Oops.

While here, make bios.c compile and add it to files.amd64.

Users should move to the new geom_vinum implementation instead.

The refcount logic which is being added to devices to enable safe module
unloading and the buf/vm work also in progress would require a major rework

8985c52bb6 Device driver for the Cypress CY7C637xx and CY7C640/1xx families of USB
to RS232 bridges, such as the one found in the DeLorme Earthmate USB GPS
receiver (which is the only device currently supported by this driver).

While other USB to serial drivers in the tree rely heavily on ucom, this
one is self-contained.  The reason for that is that ucom assumes that
the bridge uses bulk pipes for I/O, while the Cypress parts actually
register as human interface devices and use HID reports for configuration
and I/O.

The driver is not entirely complete: there is no support yet for flow
control, and output doesn't seem to work, though I don't know if that is
because of a bug in the code, or simply because the Earthmate is a read-
only device.

ed062c8d66 Refactor a bunch of scheduler code to give basically the same behaviour
but with slightly cleaned up interfaces.

The KSE structure has become the same as the "per thread scheduler
private data" structure. In order to not make the diffs too great
one is #defined as the other at this time.

The KSE (or td_sched) structure is  now allocated per thread and has no
allocation code of its own.

Concurrency for a KSEGRP is now kept track of via a simple pair of counters
rather than using KSE structures as tokens.

Since the KSE structure is different in each scheduler, kern_switch.c
is now included at the end of each scheduler. Nothing outside the
scheduler knows the contents of the KSE (aka td_sched) structure.

The fields in the ksegrp structure that are to do with the scheduler's
queueing mechanisms are now moved to the kg_sched structure.
(per ksegrp scheduler private data structure). In other words how the
scheduler queues and keeps track of threads is no-one's business except
the scheduler's. This should allow people to write experimental
schedulers with completely different internal structuring.

A scheduler call sched_set_concurrency(kg, N) has been added that
notifies teh scheduler that no more than N threads from that ksegrp
should be allowed to be on concurrently scheduled. This is also
used to enforce 'fainess' at this time so that a ksegrp with
10000 threads can not swamp a the run queue and force out a process
with 1 thread, since the current code will not set the concurrency above
NCPU, and both schedulers will not allow more than that many
onto the system run queue at a time. Each scheduler should eventualy develop
their own methods to do this now that they are effectively separated.

Rejig libthr's kernel interface to follow the same code paths as
linkse for scope system threads. This has slightly hurt libthr's performance
but I will work to recover as much of it as I can.

Thread exit code has been cleaned up greatly.
exit and exec code now transitions a process back to
'standard non-threaded mode' before taking the next step.
