2008-12-16ALSA: hda - Add Nvidia vendor id stringTakashi Iwai1-0/+1
Added Nvidia (0x10de) to the vendor id list. Cleaned up the codec name strings accordingly. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-11-30ALSA: hda - Add a new function to seek for a codec IDMauro Carvalho Chehab1-0/+61
Gateway notebooks have their ID inside codec vendor ID, not at PCI ID. Due to that, model auto-detection were not possible with the standard seek method. This is what is found at lspci -vnn: 00:14.2 Audio device [0403]: ATI Technologies Inc SB450 HDA Audio [1002:437b] (rev 01) Subsystem: ATI Technologies Inc SB450 HDA Audio [1002:437b] Yet, autodetection is possible, since the codec properly reflects the vendor at the Subsystem ID: $ cat /proc/asound/card0/codec#0 |head -4 Codec: SigmaTel STAC9250 Address: 0 Vendor Id: 0x83847634 Subsystem Id: 0x107b0367 This patch adds a new autodetection function that seeks for codec subsystem ID.

2008-11-28ALSA: hda - Don't export symbols when built-in kernelTakashi Iwai1-74/+74
The global functions in hda_codec.c and other core parts are only for HD-audio codec and controller drivers. When the HD-audio driver is built in kernel, all stuff have to be statically linked, thus we don't need any exports. This patch introduces a conditional macro to do export only when needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-28ALSA: hda - Check MODULE instead of CONFIG_SND_HDA_INTEL_MODULETakashi Iwai1-2/+2
Checking MODULE is more generic. Also a cosmetic comment change. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-28ALSA: hda - Clear codec->proc_widget_hook at resetTakashi Iwai1-0/+1
Clear the remaining pointer at snd_hda_codec_reset() to avoid Oops. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-27ALSA: hda - Modularize HD-audio driverTakashi Iwai1-44/+143
Split the monolithc HD-audio driver into several pieces: - snd-hda-intel HD-audio PCI controller driver; loaded via udev - snd-hda-codec HD-audio codec bus driver - snd-hda-codec-* Specific HD-audio codec drivers When built as modules, snd-hda-codec (that is invoked by snd-hda-intel) looks up the codec vendor ID and loads the corresponding codec module automatically via request_module(). When built in a kernel, each codec drivers are statically hooked up before probing the PCI. This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module information for each driver, and driver-linking codes between codec-bus and codec drivers. TODO: - Avoid EXPORT_SYMBOL*() when built-in kernel - Restore __devinit appropriately depending on the condition Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-27ALSA: hda - Fix PCM reconfigureTakashi Iwai1-69/+93
The reconfiguration of PCM affected all PCM streams on the bus, but this this should be done rather only for the target codec. This patch does the following: - introduce bitmap indicating the PCM device usages on a hda_bus - refactor the PCM build functions - fix __devinit prefix in some fucntions - add a proper ifdef around HDA-reconfig-specific functions Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-27ALSA: hda - Move power_save option to hda_intel.cTakashi Iwai1-10/+6
Move power_save option into hda_intel.c, and make a field in hda_bus, instead of keeping module parameters in separate files. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-27ALSA: hda - make some functions staticTakashi Iwai1-13/+1
Minor clean ups: move snd_hda_codecs_inuse() into hda_intel.c and make static. Also, make snd_hda_query_supported_pcm() static as it's used only in hda_codec.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-11-25ALSA: hda - Fix caching of SPDIF status bitsTakashi Iwai1-2/+2
SPDIF status bits controls are written via snd_hda_codec_write() without caching. This causes a regression at resume that the bits are lost. Simply replacing it with the cached version fixes the problem. Reference: http://lkml.org/lkml/2008/11/24/324 Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-21ALSA: hda - Fix build without CONFIG_PROC_FSTakashi Iwai1-0/+30
snd_print_pcm_rates() and snd_print_pcm_bits() are used by both hda_proc.c and hda_eld.c, thus they have to be defined in the common place. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-21ALSA: hda - Fix double free of jack instancesTakashi Iwai1-0/+1
The jack instances created in patch_sigmatel.c may be double-freed. The device management code checks the invalid element, and thus there is no real breakage, but it spews annoying warning messages. But, we can't simply remove the release calls of these jack instances because they have to be freed when the codec is re-configured. Now, a new flag, bus->shutdown is introduced to indicate that the bus is really being unloaded, i.e. the objects managed by the device manager will be automatically deleted. We release these objects only when this flag isn't set. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-11-06ALSA: hda - simplify hda_bus ops callbacksTakashi Iwai1-15/+47

2008-11-04ALSA: hda - Don't create empty PCM streamsTakashi Iwai1-0/+5
Due to the hda-reconfiguration patches, the check of empty stream is gone, and this results in an error with the codec setup with empty streams. This patch adds the check again to avoid the error at probing. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-11-04ALSA: hda - Fix possible NULL dereferenceTakashi Iwai1-1/+3

2008-09-09ALSA: hda: slave digital out supportMatthew Ranostay1-2/+50
Added support for playing a stream on multiple digital outs. This is done by defining codec->slave_dig_outs as array of hda_nid_t with a null-terminated entry to set the slave SPDIF outs, in which the slave outs have cloned settings of the master out (e.g. dig_out_nid).

2008-08-13ALSA: hda - Don't reset SPDIF in each status changeTakashi Iwai1-2/+2
The SPDIF output is toggled at each time any SPDIF status bits are changed because of the known problems on some codecs. But, this also results in loosing the sync, and the problem is more obvious on HDMI output over SPDIF. Since the toggle is necessary only for some codecs, we should check whether this workaround is needed and skip if unnecessary.
