that conjures up the device node so it isn't true PNP. Noticed by jhb@.
* Add an attachment for esscontrol since it too uses ISA_PNP_PROBE.
* Move an attachment from snd_mss to snd_pnpmss. The latter is the real
PNP user.
* Fix a bug where caches were flushed on non-C3 transitions.
* Be sure a working flush cache instruction is present before using it.
* Disable C3 completely if it isn't present.
may want to shut down here but the chance of BIOS vendors getting this
wrong is high. They're only supposed to announce this when all batteries
hit their critical level but past experience indicates we should be
conservative about this for now.
- Trade off granularity to reduce overhead, since the current model
doesn't appear to reduce contention substantially: move to a single
harvest mutex protecting harvesting queues, rather than one mutex
per source plus a mutex for the free list.
- Reduce mutex operations in a harvesting event to 2 from 4, and
maintain lockless read to avoid mutex operations if the queue is
full.
- When reaping harvested entries from the queue, move all entries from
the queue at once, and when done with them, insert them all into a
thread-local queue for processing; then insert them all into the
empty fifo at once. This reduces O(4n) mutex operations to O(2)
mutex operations per wakeup.
In the future, we may want to look at re-introducing granularity,
although perhaps at the granularity of the source rather than the
source class; both the new and old strategies would cause contention
between different instances of the same source (i.e., multiple
network interfaces).

with acpi but the timer runs twice as fast. Note that the main problem
(system doesn't work properly with acpi disabled) should be fixed separately.
Changes:
* Add a quirk to disable the timer
* Merge the P5A and P5A-B quirks since they appear to be based on the
same ASL.

completely empty table since ACPI-CA reports this as a problem.

This requires only one change to support. Rather than keying on the
size of the resource being 2, instead key off the end & 7 being 3.
This covers the same cases that the size of 2 would catch, but also
covers the new above case.
In addition, I think it is clearer to use the end in preference to the
size and start for case #8 as well. Turns two tests into one, and
catches no other cases.
Make minor commentary changes to deal with new case #9.
# This change is specifically minimal to allow easy MFC. A more
# extensive change will go into current once I've had a chance to test

data endpoints. The control endpoint doesn't need read/write/poll
operations, and more importantly, the thread counts should be
separate so that the control endpoint can properly reference itself
while deleting and recreating the data endpoints.
* Add some macros that handle referencing/releasing devices, and use them
for sleeping/woken-up and open/close operations as apppropriate.
* Use d_purge for FreeBSD, and a loop testing the open status for all
the endpoints for NetBSD and OpenBSD, so that when the device is
detached, the right thing always happens.
restart the current waiting transfer. If this isn't done, the device's
next transfer (that we would like to do a short read on) is going to
return an error -- for short transfer.
* For bulk transfer endpoints, restore the maximum transfer length each
time a transfer is done, or the first short transfer will make all the
rest that size or smaller.
* Remove impossibilities (malloc(M_WAITOK) == NULL, &var == NULL).
