kernel resumes normal (non-cold, able to run processes, etc) operation.
Previously we were relying on specific DVACT_RESUME op's in drivers
creating callback/threads themselves, but that has become too common,
indicating the need for a built-in mechanism.

cleaning up some shutdown-hook related code on the way.

with the IPL_MPSAFE flag. In certain circumstances, this prevents
interrupt handlers from waiting the global kernel_lock possibly (hold
by slower code) to be released.

structures (including sound-card registers) from concurent
access by syscall and interrupt code-paths. Since critical
sections remain the same, calls to splraise/spllower can be
safely replaced by calls to mtx_enter/mtx_leave with two
exceptions: (1) mutexes are not reentrant (the inner splraise
is thus removed), and (2) we're not allowed to sleep with a
mutex (either msleep is used or the mutex is released before
sleeping).
ok and help from kettenis, a lot of work from armani

that's ever used it, and it's long since been changed to use
DVACT_{QUIESCE,SUSPEND,RESUME} instead.
ok deraadt@, dlg@; miod@ also agreed with this idea when I brought it
up a few weeks ago

don't run it upon resume. We now save and restore the MSI registers in the
generic PCI code, so it is no longer necessary and will hurt us when we
actually start using MSI.

* deal with the possibility of the hardware being detached, as could
happen with expresscard. from deraadt@
* only return 1 if an interrupt was actually serviced. fixes "constant
interrupts when the device isn't being used" issue reported by oga@.
|

detach happens after the hardware is gone, so don't try to touch
the hardware in the detach path
but azalia_pci_detach is called if the device coiuld not be initialized.
in that case, shut the hardware down.

number of widget connection list entries. if the high bit is set in
a connection list entry, all widgets between the previous and current
entry are connected. go through the connection list entry once to
figure out how many connections there are, then go through it again
to build the connection list.

DVACT_SUSPEND, therefore DVACT_QUIECE can do standard sleeping operations
to get ready.
Discussed quite a while back with kettenis and jakemsr, oga suddenly needed
it as well and wrote half of it, so it was time to finish it.

than one block of data since the interrupt handler was last run.
when azalia detects these situations, it will print a line to the
dmesg buffer like:
stream 1: swpos XXXX hwpos XXXX, adding intr
getting these messages in itself is not bad, but if audio breaks, I
need to see these messages. this will be changed to a DPRINTF once
I get more feedback.

if so, don't do anything on suspend/resume. should fix crash reported
by mlarkin.
|

for both structs, the new members are 'bps' and 'msb', which
describe the number of bytes per sample and data alignment in the
sample, respectively. drivers must properly set these fields in
the 'query_encoding', 'set_parameters' and 'get_default_params'
hardware interface methods.
