2013-01-12ALSA: hda - Add Loopback Mixing controlTakashi Iwai
For codecs that have individual routes going through a loopback mixer (like VIA codecs), we need to provide an explicit switch to choose whether the output goes through mixer or directly from DAC. This patch adds the check for such paths and creates "Loopback Mixing" enum control when available. It won't influence on codecs like Realtek or others where the loopback mixer is connected independently from the primary output routes. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Correct aamix output pathsTakashi Iwai
The output paths including aamix should be parsed only for the first output. The surround paths including aamix must be wrong, since it would mix all streams, i.e. all channels would be mixed into a single and multiplexed again. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Initialize digital-input path properlyTakashi Iwai
Call the path activation for the digital input pin properly, not only setting the pin control. Also add spec->digin_path for keeping the path index. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Manage using output/loopback path indicesTakashi Iwai
Instead of search for the path with the certain route at each time, keep the path index for each output and loopback, and just use it when referred. In this implementation, the path index number begins with one, not zero (although I've been writing in C over decades). It's just to make the check for uninitialized values easier. So far, the input paths aren't handled with indices yet, but still picked up via snd_hda_get_nid_path() at each time. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Fix multi-io pin assignment in create_multi_out_ctls()Takashi Iwai
The multi-io pins are calculated with a blind assumption of cfg->line_outs = 1. This isn't always true. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Simplify the multi-io assignment with multi speakersTakashi Iwai
When speakers are chosen as the the primary output during evaluation, we did some tricks to assign the possible multi-io jacks with a certain offset value to multi_out dacs. This was a workaround for the case with multiple speakers like Acer Aspire. But this is quite ugly at the same time and the resultant code is hard to understand. More badly, it works wrongly for 2.1 speakers like Apple iMac91. In this patch, instead of fiddling with the offset to multi_out dacs, simply add a certain badness number if headphone(s) + multi-ios are possible. This simplify the code a bit, and it's more robust.

2013-01-12ALSA: hda - Check the existing path in snd_hda_add_new_path()Takashi Iwai
If the requested path has been already added, return the existing path instance instead of adding a duplicated instance. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Avoid duplicated path creationsTakashi Iwai
When the paths are created in map_singles(), we don't have to re-create new paths in try_assign_dacs(). Just evaluate the badness and skip to the next item. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Initialize output paths with current active statesTakashi Iwai
Set path->active flag at the path creation time and let the paths initialized according to the current path->active state in set_output_and_unmute(). This allows to modify the active flag of some output paths dynamically, e.g. switching the front output route with or without aamix like patch_via.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Don't skip amp init for activated pathsTakashi Iwai
activate_amp() in the generic parser checks whether the given NID is included in any active paths and skips it if found. This was a workaround for avoiding disabling the widgets in the active paths when one path is disabled, thus it shouldn't be applied to the case for path activation. Due to this wrong check, some analog loopback paths haven't been initialized correctly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add hooks for HP/line/mic auto switchingTakashi Iwai
... as a preliminary work for migrating patch_sigmatel.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Revive snd_hda_get_conn_list()Takashi Iwai
Manage the connection list cache using linked lists instead of snd_array, and revive snd_hda_get_conn_list() again, so that we don't have to keep the expanded values locally. This will reduce the stack usage by recursive call of snd_hda_get_conn_index() or parse_nid_path() of the generic parser. The list management doesn't include any mutex protection, thus the caller needs to take care of race appropriately. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add codec->inv_jack_detect flagTakashi Iwai
Yet another broken hardware workaround: there are hardware indicating the inverted jack detection bit result. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add inv_eapd flag to struct hda_codecTakashi Iwai
Add the new flag, codec->inv_eapd, indicating that the EAPD implementation is inverted. There are always broken hardware in the world. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Implement independent HP controlTakashi Iwai
Similar like the implementation in patch_analog.c and patch_via.c, the generic parser can provide the independent HP PCM stream now. It's enabled when spec->indep_hp is set by the caller while parsing. Currently no dynamic PCM switching as in patch_via.c is implemented yet. The control returns -EBUSY when the value is changed during PCM operations. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Allow aamix in the primary output pathTakashi Iwai
Allow the path including the loopback mixer widget in the primary output channel as an alternative in the generic codec parser. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Define HDA_PARSE_* for snd_hda_parse_nid_path() argumentTakashi Iwai
... instead of numbers. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Fix typos in debug_show_configs()Takashi Iwai
It never showed the 4th line out and headphone pins since quite ago. Oh well. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add more debug prints about new pathsTakashi Iwai
Add a better debug print code to show the new assigned paths in generic parser. It appears only with CONFIG_SND_DEBUG_VERBOSE=y. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Drop spec->channel_mode field from hda_gen_specTakashi Iwai
It's never used in the generic parser. It was there from the old Realtek code, which has been dropped quite ago, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Fix PCM name string for generic parserTakashi Iwai
When a PCM name string is generated from the chip name, it might become strange like "CX20549 (Venice) Analog". In this patch, the parser tries to drop the invalid words like "(Venice)" in the PCM name string. Also, when the name string is given beforehand by the caller, respect it and use it as is. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Use cached version for changing pins in hda_generic.cTakashi Iwai
There is no reason to avoid snd_hda_set_pin_ctl_cache() there. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Dynamically turn on/off EAPD in generic codec driverTakashi Iwai
When spec->own_eapd_ctl isn't set, try to turn on/off EAPD on demand for each pin. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Fix initialization of primary outputs in hda_generic.cTakashi Iwai
There were some old codes that look not stable enough, which was derived from the old Realtek code. The initialization for primary output in init_multi_out() needs to consider the case of shared DAC. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Refactor init_extra_out() in hda_generic.cTakashi Iwai
Just a small clean up by splitting a function. No functional changes at all. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Clear unsol enable bits on unused pins in generic parserTakashi Iwai
For preliminary works to migrate the generic parser for Conexant codecs: the same function is ported to hda_generic.c. But now it looks through the jack detect table so that it can cover better. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add spec->vmaster_mute_enum flag to generic parserTakashi Iwai
Add a flag to indicate whether the vmaster mute hook enum is exposed or not. Conexant codecs may want not to expose the control depending on the model. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Begin HDA_GEN_* event tag from 1Takashi Iwai
... to distinguish from the invalid event type. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Increase the max depth of widget connectionsTakashi Iwai
Old codecs like AD1986A tend to have long paths as they were just made to be the way like AC97. The current max depth 5 can be too short for such devices. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Avoid access of amp cache element outside mutexTakashi Iwai
The access to a cache array element could be invalid outside the mutex, so copy locally for the later references. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Fix wrong dirty check in snd_hda_codec_resume_amp()Takashi Iwai
The dirty entry has to be checked at the beginning in the loop, not in the inner loop for channels. This caused a regression that the right channel isn't properly written. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Do sequential writes in snd_hda_gen_init()Takashi Iwai
This would reduce the number of actually executed verbs. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add / fix comments about capture vol/sw controls in hda_generic.cTakashi Iwai
A bit of details won't hurt. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add missing amp cache flush for bound capture vol/sw ctlsTakashi Iwai
The bound capture volume and switch controls use the cached amp updates, but it's missing the flushing at the end. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add snd_hda_codec_flush_*_cache() aliasesTakashi Iwai
It makes easier to understand although these are identical with snd_hda_codec_resume_*() functions. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Flush dirty amp caches before writing inv_dmic fixTakashi Iwai
The inverted dmic fix overwrites the right channel amp value, but it would work only when the amp values have been already actually written. Put snd_hda_codec_resume_amp() before the amp write for flushing caches. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Check CORB overflowTakashi Iwai
Add an overflow check of CORB in HD-audio controller and codec drivers so that flood of sequential writes would work properly. In the controller side, add a check of CORB read-pointer to make returning -EAGAIN when it's full. Meanwhile in the codec side, when -EAGAIN error is received, it retries the write after flushing the pending verbs (calling get_response() essentially does it). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Clear cached_write flag in snd_hda_codec_resume_*()Takashi Iwai
These functions are supposed to be called at finishing the cached sequential writes, so clear the flag properly for lazy developers who often forget details. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Clear dirty flag upon cache writeTakashi Iwai
When verbs or amps are actually written to the hardware, we can clear dirty flag so that the later snd_hda_codec_resume_*() calls can skip these verbs / amps. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Allow one chance for zero NID in connection listTakashi Iwai
The commit [2e9bf24: ALSA: hda_codec: Check for invalid zero connections] trims the whole connection list when an invalid value is reported by the hardware. But some codecs (at least AD1986A) may give a zero NID in the middle of the connection list, so dropping the whole list isn't good for such cases. In this patch, as a workaround, allow a single zero NID in the read connection list. If it hits zero twice, it's handled as an error, so that we can avoid "too many connections" errors. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Use "Capture Source" for single sourcesTakashi Iwai
In general we prefer "Capture Source" to "Input Source". The latter was chosen in many places just because "Capture Source" label doesn't work well with the current alsa-lib mixer abstraction when multiple instances are present. But when we know that there is a single input-source element, we can safely choose "Capture Source" label. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Use generic parser codes for Realtek driverTakashi Iwai
The next migration step is to use the common code in generic driver for Realtek driver. This is no drastic change and there should be no real functional changes, as the generic parser code comes from Realtek driver originally. As Realtek driver requires the generic parser code, it needs a reverse-selection of CONFIG_SND_HDA_GENERIC kconfig. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Export standard jack event handlers for generic parserTakashi Iwai
These handlers are supposed to be called externally from the codec drivers once when they need to handle own jack events. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Fix NULL dereference in snd_hda_gen_build_controls()Takashi Iwai
When no controls are assigned in the parser (e.g. no analog path), spec->kctls.list is still NULL. We need to check it before passing to snd_hda_add_new_ctls(). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Move the call of snd_hda_parse_pin_defcfg() from ↵Takashi Iwai
snd_hda_gen_parse_auto_config() In some cases, we want to manipulate the auto_pin_cfg table before passing to snd_hda_gen_parse_auto_config() (e.g. Realtek SSID check code fiddles with the headphone pin). Also passing ignore_pins just for snd_hda_parse_pin_defcfg() isn't good. In this patch, snd_hda_gen_parse_auto_config() is changed to receive the auto_pin_cfg table to be parsed. The passed auto_pin_cfg table must have been initialized (typically by calling snd_hda_gen_parse_auto_config()) beforehand by the caller. Also together with this change, spec->parse_flags is also removed. Since this was referred only at the place calling snd_hda_parse_pin_defcfg(), no longer needed to be kept in spec. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Export snd_hda_gen_add_kctl()Takashi Iwai
It may be used in other codec drivers, so let it free. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add EAPD control to generic parserTakashi Iwai
Enable EAPD in output path initializations automatically unless the new flag spec->own_eapd_ctl is set. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Merge Realtek parser code to generic parserTakashi Iwai
Finally the whole generic parser code in Realtek driver is moved into hda_generic.c so that it can be used for generic codec driver. The old dumb generic driver is replaced. Yay. The future plan is to adapt this generic parser for other codecs, i.e. the codec driver calls the exported functions in generic driver but adds some codec-specific fixes and setups. As of this commit, the complete driver code is still duplicated in Realtek codec driver. The big code reduction will come from now on. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda/realtek - Remove redundant argument from alc_mux_select()Takashi Iwai
The argument "force" is always false in the recent code. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - More generic auto-mic switching for Realtek codecsTakashi Iwai
This patch extends the capability of the auto-mic feature. Instead of limiting the automatic input-source selection only to the mics (internal, external and dock mics), allow it for generic inputs, e.g. switching between the rear line-in and the front mic. The logic is to check the attribute and location of input pins, and enable the automatic selection feature only if all such pins are in different locations (e.g. internal, front, rear, etc) and line-in or mic pins. That is, if multiple input pins are assigned to a single location, the feature isn't enabled because we don't know the priority. (You may wonder why this restriction doesn't exist for the headphone automute. The reason is that the output case is different from the input: the input source is an exclusive selection while the output can be multiplexed.) Note that, for avoiding regressions, the line-in auto switching feature isn't activated as default. It has to be set explicitly via spec->line_in_auto_switch flag in a fixup code.
