2009-11-16ALSA: hda - proc - add support for dynamic controls to mixer<->NID mappingJaroslav Kysela
This patch adds support for dynamically created controls to proc codec file (Control: lines). Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-11-16ALSA: hda - proc - introduce Control: lines to show mixer<->NID assignmentJaroslav Kysela
This is an initial patch to show universal control<->NID assigment in proc codec file. The change helps to debug codec related problems. Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-11-16ALSA: hda_intel: Digital PC Beep - change behaviour for input layerJaroslav Kysela
Original implementation was keeping registered input device for SND_BEEP and SND_TONE events all time. This patch changes this behaviour: If digital PC Beep is turned off using universal control switch, the input device is unregistered. Explanation: The kd_mksound() send SND_BEEP and SND_TONE only to last registered device acceping those events. It means that the HDA Intel audio driver blocks also the internal PC Speaker device (pcspkr.c driver) even if the HDA Beep is muted. The user can easy disable all beeps using 'setterm -blength 0' or 'xset b off' command. Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-11-11ALSA: hda - Add power on/off counterTakashi Iwai
Added the power on/off counter and expose via sysfs files. The sysfs files, power_on_acct and power_off_acct, are created under each codec hwdep sysfs directory (e.g. /sys/class/sound/hwC0D0). The files show the msec length of the codec power-on and power-off, respectively. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-11-10ALSA: hda - proc - show which I/O NID is associated to PCM deviceJaroslav Kysela
Output something like: Node 0x02 [Audio Output] wcaps 0x11: Stereo Device: name="ALC888 Analog", type="Audio", device=0, substream=0 Converter: stream=0, channel=0 ... Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-11-10ALSA: hda - Add reboot notifier to each codecTakashi Iwai
Add reboot notifier to each codec so that it can do some workarounds needed for reboot. So far, patch_sigmatel.c calls its shutup routine for avoiding noises at reboot on some HP machines.

2009-10-30ALSA: hda - allow up to 4 HDMI devicesWu Fengguang
The new Intel HDMI codec supports 2 independant HDMI/DisplayPort pipes. We'll be exporting them as 2 pcm devices. So bump up the allowed number of HDMI devices. Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-10-30ALSA: hda - vectorize get_empty_pcm_device()Wu Fengguang
This unifies the code and data structure, and makes it easy to add more HDMI devices. Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-09-02ALSA: hda - Fix obsolete CONFIG_SND_DEBUG_DETECTTakashi Iwai

2009-08-03ALSA: hda: track CIRB/CORB command/response states for each codecWu Fengguang
Recently we hit a bug in our dev board, whose HDMI codec#3 may emit redundant/spurious responses, which were then taken as responses to command for another onboard Realtek codec#2, and mess up both codecs. Extend the azx_rb.cmds and azx_rb.res to array and track each codec's commands/responses separately. This helps keep good codec safe from broken ones.

2009-07-27ALSA: hda - Add exception for volume-knob in snd_hda_get_connections()Takashi Iwai
Volume-knob widgets may have connections even if they have no CONN_LIST cap bit. Allow the query exceptionally in snd_hda_get_connections(). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-07-27ALSA: hda - Introduce get_wcaps_type() macroTakashi Iwai
Add a helper macro to retrieve the widget type from wiget cap bits. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-07-22ALSA: hda-intel: Cleanups for widget connection list handlingJaroslav Kysela
This patch adds a check to snd_hda_get_connections() routine for presence of AC_WCAP_CONN_LIST. Also, make sure that negative error codes from noted route are handled on all places as errors. Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-07-22ALSA: hda - Reduce click noise at power-savingTakashi Iwai
Add some tricks to reduce the click noise at powering down to D3 in the power saving mode on STAC/IDT codecs. The key seems to be to reset PINs before the power-down, and some delay before entering D3. The needed delay is significantly long, but I don't know why. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-07-19ALSA: hda_codec: Check for invalid zero connectionsJaroslav Kysela
To prevent "Too many connections" message and the error path for some HDMI codecs (which makes onboard audio unusable), check for invalid zero connections for CONNECT_LIST verb. Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-07-17ALSA: hda - Fix the previous sanity check in make_codec_cmd()Takashi Iwai
The newly added sanity-check for a codec verb can be better written with logical ORs. Also, the parameter can be more than 8bit. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-07-17ALSA: hda - add bounds checking for the codec command fieldsWu Fengguang
A recent bug involves passing auto detected >0x7f NID to codec command, creating an invalid codec addr field, and finally lead to cmd timeout and fall back into single command mode. Jaroslav fixed that bug in alc880_parse_auto_config(). It would be safer to further check the bounds of all cmd fields.

2009-07-10ALSA: hda - Check codec errors in snd_hda_get_connections()Takashi Iwai
The codec read errors in snd_hda_get_connections() are ignored so far, and it causes a problem like the bug in the commit 9d30937accf2c01e8b0bd59787409a7348cbbcb7 ALSA: hda_intel: more strict alc880_parse_auto_config dig_nid checking Better to check errors in the function and returns a proper error code rather than passing bogus NID values.

2009-07-03ALSA: hda - Don't override maxbps for FLOAT sharing with linear formatsTakashi Iwai
When FLOAT PCM format is available but together with other linear PCM formats, don't override maxbps value. For FLOAT format, it's always 32, thus it can be better checked in snd_hda_calc_stream_format(). Otherwise the maxbps 32 might be used wrongly even if the linear PCM doesn't support it. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-07-03ALSA: hda - Avoid invalid formats and rates with shared SPDIFTakashi Iwai
Check whether formats and rates don't result in zero due to the restriction of SPDIF sharing. If any of them can be zero, disable the SPDIF sharing mode instead. Otherwise it will lead to a PCM configuration error. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-07-01ALSA: hda - Allow FLOAT PCM formatTakashi Iwai
So far, the FLOAT PCM format is used only exclusivley set. But this can be a combination with other formats. This patch changes the parser to allow the FLOAT format in addition to other PCM formats. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-24ALSA: hda - Don't call snd_hda_codec_configure in snd_hda_codec_new()Takashi Iwai
The codec setup call via snd_hda_codec_configure() isn't necessarily called in snd_hda_codec_new(). For the later added feature, it's better to change the code flow like: - create all codec instances - configure each codec Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-17ALSA: hda - Fix memory leak at codec creationTakashi Iwai
The codec->modelname field is allocated twice in snd_hda_codec_new(). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: hda - Limit codec-verb retry to limited hardwaresTakashi Iwai
The reset of a BUS controller during operations is somehow risky and shouldn't be done inevitably for devices that have apparently no such codec-communication problems. This patch adds the check of the hardware and limits the bus-reset capability. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-02ALSA: hda - Add codec bus reset and verb-retry at critical errorsTakashi Iwai
Some machines machine cause a severe CORB/RIRB stall in certain weird conditions, such as PA access at the start up together with fglrx driver. This seems unable to be recovered without the controller reset. This patch allows the bus controller reset at critical errors so that the communication gets recovered again. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-05-26ALSA: hda - Support sync after writing a verbTakashi Iwai
This patch adds a debug mode to make the codec communication synchronous. Define SND_HDA_SUPPORT_SYNC_WRITE in hda_codec.c, and the call of snd_hda_codec_write*() will become synchronous, i.e. wait for the reply from the codec at each time issuing a verb. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-05-16ALSA: hda - Split codec->name to vendor and chip name stringsTakashi Iwai
Split the name string in hda_codec struct to vendor_name and chip_name strings to be stored directly from the preset name. Since mostly only the chip name is referred in many patch_*.c, this results in the reduction of many codes in the end. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-04-21ALSA: hda - minor optimization in hda_set_power_state()Takashi Iwai

2009-04-21ALSA: hda - Retry codec-verbs at errorsTakashi Iwai
The current error-recovery scheme for the codec communication errors doesn't work always well. Especially falling back to the single-command mode causes the fatal problem on many systems. In this patch, the problematic verb is re-issued again after the error (even with polling mode) instead of the single-cmd mode. The single-cmd mode will be used only when specified via the command option explicitly, mainly just for testing. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-04-21ALSA: hda - Cache PCM and STREAM parameters queriesTakashi Iwai
Cache quries for PCM and STREAM parameters as well as ampcap and pincap sharing the hash table. This will reduce the superfluous access of the same codec verbs. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-04-15ALSA: hda - Fix the cmd cache keys for amp verbsTakashi Iwai
Fix the key value generation for get/set amp verbs. The upper bits of the parameter have to be combined with the verb value to be unique for each direction/index of amp access.

2009-03-23ALSA: hda - Use cached calls to get widget caps and pin capsTakashi Iwai
