2013-10-17ALSA: hda - Move mutex from hda_eld to per_pin in HDMI codec driverTakashi Iwai
Since the lock is used primarily in patch_hdmi.c, it's better to move it in the local struct instead of exporting in hda_eld. The only functions requiring the lock in hda_eld.c are proc accessors. So in this patch, the proc entry and its creation/deletion/accessors are moved into patch_hdmi.c, together with the mutex lock to pin_spec struct. The former proc info functions are exported so that they can be called from patch_hdmi.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-06-19ALSA: hda - Fix missing Mic Boost controls for VIA codecsTakashi Iwai
Some VIA codecs like VT1708S have Mic boost amps in the mic pins but they aren't exposed in the capability bits. In the past driver code, we override the pin caps and create mic boost controls forcibly. While transition to the generic parser, we lost the mic boost controls although the pin caps are still overridden, because the generic parser code checks the widget caps, too. So this patch adds a new helper function to allow the override of the given widget capability bits, and makes VIA codecs driver to add the missing input-amp capability bit.

2013-06-18ALSA: hda - Fix return value of snd_hda_check_power_state()Takashi Iwai
The refactoring by commit 9040d102 introduced the new function snd_hda_check_power_state(). This function is supposed to return true if the state already reached to the target state, but it actually returns false for that. An utterly stupid typo while copy & paste. Fortunately this didn't influence on much behavior because powering up AFG usually powers up the child widgets, too. But the finer power control must have been broken by this bug.

2013-03-13ALSA: hda - Don't apply EAPD power filter as defaultTakashi Iwai
So far, the driver doesn't power down the widget at going down to D3 when the widget node has an EAPD capability and EAPD is actually set on all codecs unless codec->power_filter is set explicitly. This caused a problem on some Conexant codecs, leading to click noises, and we set it as NULL there. But it is very unlikely that the problem hits only these codecs. Looking back at the development history, this workaround for EAPD was introduced just for some laptops with STAC9200 codec, then we applied it blindly for all. Now, since it's revealed to have an ill effect, we should disable this workaround per default and apply only for the known requiring systems. The EAPD workaround is implemented now as snd_hda_codec_eapd_power_filter(), and this has to be set explicitly by the codec driver when needed. As of now, only patch_stac9200() sets this one.

2013-02-19ALSA: hda - hdmi: Protect ELD bufferDavid Henningsson
Because the eld buffer can be simultaneously accessed from both workqueue context (updating) and process context (kcontrol read), we need to protect it with a mutex to guarantee consistency. To avoid holding the mutex while reading the ELD info from the codec, we introduce a temporary eld buffer.

2013-01-23ALSA: hda - Add chained_before flag to the fixup entryTakashi Iwai
Sometimes we want to call a fixup after applying other existing fixups, but currently the fixup chain mechanism allows only the call the others after the target fixup. This patch adds a new flag, chained_before, to struct hda_fixup, for allowing the chained call before the current execution. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-22ALSA: hda - Combine snd_hda_codec_flush_*_cache() to a single functionTakashi Iwai
Since both snd_hda_codec_flush_amp_cache() and snd_hda_codec_flush_cmd_cache() are called usually at the same time, we can simply combine them to a single function, snd_hda_codec_flush_cache(). Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-01-12ALSA: hda - Add a new fixup type to override pinctl valuesTakashi Iwai
Add a new fixup type, HDA_FIXUP_PINCTLS, for overriding the pinctl values of the given pins. It takes the same array of struct pintbl like HDA_FIXUP_PINS, but each entry contains the pinctl value instead of the pin default config value. This patch also replaces the corresponding codes in patch_realtek.c. Without this change, the direct call of verbs may be overridden again by the later call of pinctl restoration by the driver. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - More strict correction of invalid pinctl bitsTakashi Iwai
Check more strictly about the validity of pinctl values in snd_hda_set_pin_ctl() and correct the wrong bits automatically. Also provide the helper function to correct pinctl bits to codec drivers. This automatically fixes the invalid pinctl writes that are found in a few Realtek fixups for NID 0x0f amp like ASUS A6Rp. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add helper functions to cache the current pinctl targetTakashi Iwai

2013-01-12ALSA: hda - Move fixup code into struct hda_codecTakashi Iwai
Since the fixup code is used commonly, it's worth to move it to the common place, struct hda_codec, instead of keeping in hda_gen_spec. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda/realtek - Add path active flagTakashi Iwai
... and rewrite the initialization of output paths as a generic function that is applicable for both i/o directions. The new flag, active, is introduced to each nid_path entry. This indicates whether the given path is active, and it's used for checking whether a certain widget can be turned off or changed when a path is no longer used or newly enabled. It's still used only in the output paths. More wider adaption for input and loopback paths will be achieved in the later patch. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Introduce snd_hda_codec_amp_init*()Takashi Iwai
The new function snd_hda_codec_amp_init() (and the stereo variant) initializes the amp value only once at the first access. If the amp was already initialized or updated, this won't do anything more. It's useful for initializing the input amps that are in the part of the path but never used. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Introduce cache & flush cmd / amp writesTakashi Iwai
For optimizing the verb executions, a new mechanism to cache the verbs and amp update commands is introduced. With the new "write to cache and flush" way, you can reduce the same verbs that have been written multiple times. When codec->cached_write flag is set, the further snd_hda_codec_write_cache() and snd_hda_codec_amp_stereo() calls will be performed only on the command or amp cache table, but not sent to the hardware yet. Once after you call all commands and update amps, call snd_hda_codec_resume_amp() and snd_hda_codec_resume_cache(). Then all cached writes and amp updates will be written to the hardware, and the dirty flags are cleared. In this implementation, the existing cache table is reused, so actually no big code change is seen here. Each cache entry has a new dirty flag now (so the cache key is now reduced to 31bit). As a good side-effect by this change, snd_hda_codec_resume_*() will no longer execute verbs that have been already issued during the resume phase by checking the dirty flags.

2012-10-17ALSA: hda - Add workaround for conflicting IEC958 controlsTakashi Iwai
When both an SPDIF and an HDMI device are created on the same card instance, multiple IEC958 controls are created with indices=0, 1, ... But the alsa-lib configuration can't know which index corresponds actually to which PCM device, and both the SPDIF and the HDMI configurations point to the first IEC958 control wrongly. This patch introduces a (hackish and ugly) workaround: the IEC958 controls for the SPDIF device are re-labeled with device=1 when HDMI coexists. The device=1 corresponds to the actual PCM device for SPDIF, so it's anyway a better representation. In future, HDMI controls should be moved with the corresponding PCM device number, too.

2012-04-20ALSA: hda - Introduce snd_hda_set_pin_ctl*() helper functionsTakashi Iwai
For setting the pin-control values more safely to match with the actual pin capability bits, a copule of new helper functions, snd_hda_set_pin_ctl() and snd_hda_set_pin_ctl_cache(), are introduced. These are simple replacement of the codec verb write with AC_VERB_SET_PIN_WIDGET but do more sanity checks and filter out superfluous pin-control bits if they don't fit with the corresponding pin capabilities. Some codecs are screwed up or ignore the command when such a wrong bit is set. These helpers will avoid such secret errors. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-03-13ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook()Takashi Iwai
Since it's not always safe to assume that the vmaster hook is purely the mute-LED control, add the flag indicating whether to expose the mute-LED enum control or not. Currently, conexant codec sets this off for non-HP laptops where EAPD may be used really as EAPD. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-03-13ALSA: hda - Add "Mute-LED Mode" enum controlTakashi Iwai

2012-03-09ALSA: hda - Initialize vmaster slave volumesTakashi Iwai
When the driver is changed to use vmaster or a new slave element is added by the improvement of the parser code, user may face often the silent output because of the muted slave mixer although Master volume is properly set. And they complain. And I get upset. Although such a mixer element should be initialized via "alsactl init", it'd be more user-friendly if the known output slaves are unmuted and set to 0dB so that user can control the volume only with Master as default. Since Master is still set muted as default even with this change, no risk of the speaker blow up, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-02-03ALSA: hda - Add suffix argument to snd_hda_add_vmaster()Takashi Iwai
In most cases, the slave strings for vmaster are identical between volumes and switches except for "xxx Volume" and "xxx Switch" suffix. Now snd_hda_add_vmaster() takes the optional suffix argument so that each string can be composed with the given suffix, and we can share the slave name strings in both volume and switch calls nicely.

2012-01-10ALSA: hda - Return the error from get_wcaps_type() for invalid NIDsTakashi Iwai
When an invalid NID is given, get_wcaps() returns zero as the error, but get_wcaps_type() takes it as the normal value and returns a bogus AC_WID_AUD_OUT value. This confuses the parser. With this patch, get_wcaps_type() returns -1 when value 0 is given, i.e. an invalid NID is passed to get_wcaps().

2011-11-16ALSA: hda - Cache the jack-detection valueTakashi Iwai
Introduce a table containing the pins and their jack-detection states for avoiding the unnecessary verbs to check the pin status at each time. When the unsol event is enabled via snd_hda_jack_detect_enable(), it automatically adds the given NID to the table. Then the driver supposes that the codec driver will set the dirty flag appropariately when an unsolicited event is invoked for that pin. The behavior for reading other pins that aren't registered in the table doesn't change. Only the pins assigned to the table are cached, so far. In near futre, this table can be extended to use the central place for the unsolicited events of all pins, etc, and eventually include the jack-detect kcontrols that replace the current input-jack stuff.

2011-11-10ALSA: hda - Re-enable the check NO_PRESENCE misc bitTakashi Iwai
We disabled the check of NO_PRESENCE bit of the default pin-config in commit f4419172 temporarily. One problem was that the first implementation was wrong -- the bit after the shift must be checked. However, this would still give many regressions on machines with broken BIOS. They set this bit wrongly even on active pins. A workaround is to check whether all pins contain this bit. As far as I've checked, broken BIOSen set this bit on all pins, no matter whether active or not. In such a case, the driver should ignore this bit check. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-11-06ALSA: hda - Revert the check of NO_PRESENCE pincfg default bitTakashi Iwai
The implementation on commit [08a1f5eb: ALSA: hda - Check NO_PRESENCE pincfg default bit] seems like a mis-interpretation of specification. The spec gives the reversed bit definition. But, following the spec also causes to change so many existing device configurations, thus we can't change it so easily for now. For 3.2-rc1, it's safer to revert this check (actually this patch comments out the code). We may re-introduced the fixed version once after the wider test-case coverages are done.

2011-10-27ALSA: hda/realtek - Fix missing volume controls with ALC260Takashi Iwai
ALC260 has multiple mixer widgets connected to the shared DAC, but the driver currently doesn't check this possibility and ignores when the DAC is shared with others. This resulted in the silent output from some routes because of lack of the amp setup. This patch adds the workaround for it by checking the route even with the shared DAC, but also checking the conflict with the existing control for the very same widget NID.
