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 8574f78760 auich_set_params() sets 2 to hw_channels whenever monaural format is requested. 2002-03-10 16:48:58 +00:00
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 4cb7d87b12 Oops, I messed up the last commit, try again. 2002-02-14 12:52:01 +00:00
augustss 076c2a2de8 Make fixed rate codecs work. From Tsuyoshi Iguchi in kern/15606. 2002-02-14 03:22:36 +00:00
augustss e16f901581 Make auich support variable rate codec, and suspend/resume. 
From URA Hiroshi in PR kern/15431 (partly from OpenBSD).

augustss 27a315e2c8 Add i830M to the chip list. 2002-01-14 01:29:13 +00:00
tsutsui b87a051ec8 Call malloc(9) with M_ZERO flag instead of memset() after malloc(). 2002-01-12 16:17:05 +00:00
enami 0cd298f02e Skip not yet emulated 8bit ulinear encoding correctly. 2002-01-12 00:13:42 +00:00

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.
