According to the ICH datasheets, the flag is unchanged unless resetting
the codec.
The flag is useless after enabling bus mastering. This behavior is common
to all ICH chips. The quirk handling code is removed.
* auich_calibrate() assumes that the AC97 part is in its reset state. To
ensure this, call audio_attach_mi() after auich_calibrate().
* Explicitly support 12000Hz and 24000Hz. (Why is there a discrete list at
all?)
* Fix an obvious recording bug -- we were acking the wrong interrupt.
* Ensure that we don't get an interrupt during the AC97 speed probe by clearing
the "interrupt on completion" bit in the DMA setup.
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
auich_set_rate() modified audio_params::sample_rate to actual
sample rate though auich_set_params() rejected sample rates
other than some specific rates. For example, setting 8000Hz
with auich_set_params() modified sample_rate to 7998Hz in the
case of overclocked AC97 codec, and calling auich_set_params()
again returned with EINVAL because sample_rate was 7998Hz and
auich_set_params() rejected 7998Hz.
For now, auich_set_params() never modify audio_params::sample_rate.
Remove sc_fixed_rate and sc_ac97rate. ac97_softc has such
information.
auich_attach():
Remove VRA/VRM enabling code. ac97_attach() does it.
auich_set_rate():
Use ac97_codec_if::set_rate().
auich_get_props():
Return no AUDIO_PROP_MMAP if the codec is fixed-rate.
auichreg.h:
Remove unnecessary ICH_PM_*.
kern/16373.
- SiS 7012 support from kern/17716 submitted by Quentin Garnier.
- ICH4 support
- Experimental support for nForce MCP, AMD768 and AMD8111.
- Rename the short name for ICH3: "i830M" -> "ICH3"

auconv.c: Add conversion functions
audio.c: Sample alignment, calling conversion functions, etc.
audio_if.h: Add four hw_* members to "struct audio_params"
audiovar.h: Add conversion buffers, etc.
auich and uaudio: Add conversion request code to *_set_params().
