[alsa-devel] [PATCH v2] ASoC: rt5645: Adds push button support for rt5650
by bardliao＠realtek.com 27 Apr '15

27 Apr '15

From: Bard Liao <bardliao(a)realtek.com> rt5650 support headset button detection. Currently, the button detection is only implemented for rt5650 codec. The button detection configuration register's default value is different from rt5645. And we didn't touch the register in the driver, so we will get the wrong value when we dump the registers. We will fix it in another patch. Signed-off-by: Bard Liao <bardliao(a)realtek.com> --- * remove the change of removing the value of 0xdd in rt5645_reg[]. * add comment of handle three button detection code in one case. Mark, Can we have a separate codec driver for rt5650? rt5650 will be more popular than rt5645. Many customers are searching rt5650.c but can't find one. We have to told them rt5650 and rt5645 share the same codec driver. Also, some registers or functions are different between rt5645 and rt5650.

[alsa-devel] [PATCH 1/4] ASoC: Add helper function getting CODEC's DAPM context
by Lars-Peter Clausen 27 Apr '15

27 Apr '15

The DAPM context in the snd_soc_codec struct is redundant and scheduled to be replaced by the DAPM context in the snd_soc_component struct. This patch introduces a new helper function snd_soc_codec_get_dapm() which should be used for getting the DAPM context for a CODEC rather then directly accessing the dapm field. Once there are no more direct users of the dapm field left it is possible to transparently switch all drivers to the component DAPM context by updating snd_soc_codec_get_dapm() function.

[alsa-devel] [PATCH] ASoC: dmaengine_pcm: Make FLAG_NO_RESIDUE internal
by Lars-Peter Clausen 27 Apr '15

27 Apr '15

Whether residue can be reported or not is not a property of the audio controller but of the DMA controller. The FLAG_NO_RESIDUE was initially added when the DMAengine framework had no support for describing the residue reporting capabilities of the controller. Support for this was added quite a while ago and recently the DMAengine framework started to complain if a driver does not describe its capabilities and a lot of patches have been merged that add support for this where it was missing. So it should be safe to assume that driver on actively used platforms properly implement the DMA capabilities API. This patch makes the FLAG_NO_RESIDUE internal and no longer allows audio controller drivers to manually set the flag. If a DMA driver against expectations does not support reporting its capabilities for now the generic DMAengine PCM driver will now emit a warning and simply assume that residue reporting is not supported. In the future this might be changed to aborting with an error.

[alsa-devel] [PATCH v9 0/7] ALSA: jack: Refactoring for jack kctls
by Jie Yang 27 Apr '15

27 Apr '15

Currently only hda will create kctls for hda jacks, for asoc, people may need create jack kctls in specific driver. Here we are introducing kctls for each jack, by creating kctls and add them to jack controls list (considering exist of combo jack). At the same time, we will report events for each control in the list. With this new implementation, both HDA and soc jack kctls works fine, they are compatible for old HDA jack kctls, too. For soc, a. snd_jack_new() with NULL jack_kctl; b. for each pin, call snd_jack_add_kctls() to add one kctl(it will call snd_ctl_add() to add kctl to card); For HDA, With snd_jack_new(), we can use phantom_jack = true for phantom jack creating, and the jack kctl pointer will be filled with the new created kcontrol. Changes in v9: 1. move struct snd_jack_kctl definition to jack.c, to hides the internal implementation details; 2. some small code fixing; 3. update documentation file. Changes in v8: 1. remove snd_jack_kctl from HDA part, change snd_jack_new param to use bool for creating kcontrol at jack creating stage; 2. create jack for phantom jack, with no input device; 3. remove HDA jack get_unique_index() and index related code. Changes in v7: 1. move name generating and index getting part into ctljack.c; 2. remove exposing private_data and destructor to hda, then jack core can handle kctls by itself totally. 3. some small code fixing. Changes in v6: 1. refine kctl name generating function; 2. integrate HDA jack kctl more deeply, support phantom jack in snd_jack_new(); 3. add documentation for Jack kcontrols to explain how to use it. Changes in v5: 1. remove SND_KCTL_JACK config item, we need jack kctl once CONFIG_SND_JACK is selected. Changes in v4: 1. use snd_ctl_find_id() to get avaliable index; 2. add initial kctl for snd_jack_new(compatible for HDA); 3. add struct snd_jack_kctl * field to struct hda_jack_tbl; 4. new kctls for soc jack during jack pins creating. 5. add a patch to remove exporting snd_kctl_jack_new(). Changes in v3: 1. replace bit index with bit mask in jack_kctl; 2. add exception for SND_JACK_HEADSET and SND_JACK_AVOUT, only create one jack kctl for these two combo jacks, respectively. 3. add NULL check, mem kfree, and fix some potential risk. Change in v2: 1. define jack_kctl struct, and put jack kctl related stuff there; 2. add a patch to remove the existing controls for HDA jack.

[alsa-devel] [PATCH] ALSA: emux: Fix mutex deadlock at unloading
by Takashi Iwai 27 Apr '15

27 Apr '15

The emux-synth driver has a possible AB/BA mutex deadlock at unloading the emu10k1 driver: snd_emux_free() -> snd_emux_detach_seq(): mutex_lock(&emu->register_mutex) -> snd_seq_delete_kernel_client() -> snd_seq_free_client(): mutex_lock(&register_mutex) snd_seq_release() -> snd_seq_free_client(): mutex_lock(&register_mutex) -> snd_seq_delete_all_ports() -> snd_emux_unuse(): mutex_lock(&emu->register_mutex) Basically snd_emux_detach_seq() doesn't need a protection of emu->register_mutex as it's already being unregistered. So, we can get rid of this for avoiding the deadlock.
