must be cleared to prevent machine hanging (presently aflicts -current
and -stable).

0225c5ac86 Add calibration test to determine extent of AC97 overclocking (if any). 2001-12-18 03:29:31 +00:00

7e1f6dfe9d Modify the critical section API as follows: 
- The MD functions critical_enter/exit are renamed to start with a cpu_
  prefix.
- MI wrapper functions critical_enter/exit maintain a per-thread nesting
  count and a per-thread critical section saved state set when entering
  a critical section while at nesting level 0 and restored when exiting
  to nesting level 0.  This moves the saved state out of spin mutexes so
  that interlocking spin mutexes works properly.
- Most low-level MD code that used critical_enter/exit now use
  cpu_critical_enter/exit.  MI code such as device drivers and spin
  mutexes use the MI wrappers.  Note that since the MI wrappers store
  the state in the current thread, they do not have any return values or
  arguments.
- mtx_intr_enable() is replaced with a constant CRITICAL_FORK which is
  assigned to curthread->td_savecrit during fork_exit().

Tested on:	i386, alpha

2ae4ee833d Added a sysctl control variable "ac97rate" to allow manual tuning of 
the link rate - some ich motherboards overclock ac97 out of the box.

Will hopefully replace this with a callibration loop in time for 4.5R
freeze.

Problem reported by Luigi Rizzo and fix derived from his code (put
diff in ich.c rather than ac97.c).

b60e55dbd0 Get rid of irritating (bogus) message: 
pcm0: ac97 codec failed to reset extended mode (0, got 80)

73b9d66d9a Turn on the hardware volume buttons that are present on most laptops with 
these chips.  There is a new hint, hint.pcm.N.hwvol_config, that can be set
to 1 or 0 to select which pins the buttons are connected to.  I'm open to
suggestions on where to document this.  Also bump the number of playback
channels up to 4.
