kent 3d86014c1c Kick auich_calibrate() by config_interrupts(). 
auichi_calibrate(): If the measured rate is less than 48k, use
48k.

kent d3307382f1 auich_set_params(): Don't return in the for loop. 2002-10-08 12:31:45 +00:00
kent 1adb5c1562 auich_softc: 
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_*.

kent f06ae93219 Add some constant symbols for AC97 registers and values based on OpenBSD. 
Rename some symbols to sync with OpenBSD:
	AC97_REG_EXTENDED_ID
	-> AC97_REG_EXT_AUDIO_ID
	AC97_REG_EXTENDED_STATUS
	-> AC97_REG_EXT_AUDIO_CTRL
	AC97_CODEC_DOES_VRA/AC97_ENAB_VRA
	-> AC97_EXT_AUDIO_VRA
	AC97_CODEC_DOES_MICVRA/AC97_ENAB_MICVRA
	-> AC97_EXT_AUDIO_VRM

ac97feature: "mic channel" -> "dedicated mic channel"
ac97_attach(): print extended capabilities; VRA, DRA, SPDIF, VRM, CDAC,
SDAC, LDAC.

kent 3898bab95a - Port clock calibration code (auich_calibrate) from ich.c of FreeBSD to solve 
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"

augustss 3f41adf3be When the DAC claims to support variable rate it doesn't seem to 
always do this, so do some extra chechs and fall back on fixed rate.

kent a37082a494 whitespace and folding fix. 2002-03-23 17:17:10 +00:00
kent 4c9cd8bc91 Apply a patch by Mark Davies. 
http://mail-index.netbsd.org/port-i386/2002/03/18/0000.html

Check codec status in auich_read/write_codec().
 2002-03-21 09:17:20 +00:00
tacha 52d9a1d306 Use appropriate emulation functions and set ADC rate(not DAC date!) for recording. 
Now /dev/audio with auich becomes usable.

kent c329c38eef Sampling rate and mono-stereo conversion described in 
http://mail-index.netbsd.org/tech-kern/2002/03/04/0005.html

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().

augustss e16f901581 Make auich support variable rate codec, and suspend/resume. 
From URA Hiroshi in PR kern/15431 (partly from OpenBSD).

augustss 1339e88a86 Add a new optional method, dev_ioctl, to the audio hardware driver interface. 
It is called when an unrecognized ioctl() is performed on a device,
thus allowing ioctl()s that frob the hardware driver (like loading
microcode).

sommerfeld 851de295eb Change pci_intr_map to get interrupt source information from a "struct 
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

Tested on alpha and i386; welcome to 1.5Q

thorpej 454f740bd4 Use AC97_REG_* constants rather than defining them ourselves. 2000-11-28 16:57:16 +00:00
thorpej 443bd6369f Device driver for the built-in audio on Intel ICH, ICH0, ICH2, 
and i440MX chipsets.  Based on a driver by Michael Shalayeff,
modified somewhat by me to use bus_dma properly, and fix some
audio encoding emulation bugs.

Thanks to Manuel Bouyer for testing and feedback.
