Add a comment in ahd_clear_critical_sections() about
our need to leave ENBUSFREE set in SIMODE1 while single
stepping.
Re-arrange some delay loops so that we always perform
a read after any register write and before the delay.
This should make the delay loop more accurate.
When completing message processing for a packetized
commention, return the controller to a state where
invalid non-packetized phases will still cause protocol
violations. These are the same operations as those
performed in the clear_target_state routine in the
firmware.
Now that we have a chip with working ABORTPENDING
support (the 7901B), comment out the automatic use
of this feature until we can adequately test it.
The previous checkin updated the bug mask for the
7901B so this code was exercised.
When resetting the bus, perform an ahd_flush_device_writes()
call so that our reset assertion delay is acurately
timed from when the reset bit is written to the controller.
Remove an old comment that no longer applies.
Fix a jump in our unexpected non-packetized phase
handler to use an explicit lable. The old code
had a hardcoded jump offset that was off by one
instruction.
Add a 7901A specific feature definition.
aic79xx_pci.c:
Split out the general aic790X setup into it's own

Adjust all other PCI setup handlers to initialize the
chips basic features and type before calling the generic
handler.
Turn off a few Rev B workarounds that are not required
on the 7901B.

functions are derived from the swapctx() and restorectx() (resp)
from sys/ia64/ia64/context.s. The code is expected to be 99%
correct, but has not yet been tested.
Note that with these functions operating on mcontext_t, we also
created the foundation upon which we can implement getcontext(2)
and setcontext(2) replacements. It's not guaranteed that the use
of these syscalls and _ia64_{save|restore}_context() on the same
uicontext_t is actually going to work. Replacing the syscalls is
now trivially achieved.
This commit completes the ia64 port of libpthread itself (modulo
testing and bugfixes).
succeeds. There is a difference between how OLDCARD and NEWCARD deal
with their resources, and this code exposes that difference. I'm not
sure which behavior is correct, and will need to look into that in
more detail. However, it appears that we go ahead and allocate the
right thing in both cases that I have access to (CF cards, CDROM, and
external ata enclosures), so go ahead and ignore the failure to get
the resource for the other rid. There's already another check to make
sure that the actual allocation works correctly, and that should be
sufficient to catch cases that don't work.

The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either. It was later assuming that IF_DEQUEUE would
give him this same mbuf.
