[alsa-devel] Alsamixer: missing Speakers entry in analog output choice (chipset AV200)
by Germano Massullo 08 Jan '17

08 Jan '17

I have a Asus Xonar Essence ST soundboard (Chip: AV200) on Fedora 23 kernel 4.4.5-300.fc23.x86_64 The audiocard has 3 different outputs - Speakers - Headphones - FP Headphones that have mutual exclusion, so that when you are using one of them, you cannot use the others. Sometimes the Speakers output disappears from alsamixer. By restarting the computer, the system gets back to its normal behaviour. I attach 3 logs taken when the problem was occurring. The problem happened also in past years, but in last a 1-2 years it happened less frequently

[alsa-devel] [PATCH - alsa-lib 1/1] Change card/pid get functions to return -ENOSYS if the kernel is too old
by Adam Goode 03 Jan '17

03 Jan '17

When trying to get the pid or card of a client, the get functions will return -1 if there is no pid or card for a client. Clients have zero or one of these, so -1 is correct for these cases. But we also need to detect the case where the kernel cannot tell us if there is a card or pid, so that userspace can fallback to probing this information in the old way.

[alsa-devel] [RFC PATCH v2 0/7] AC97 device/driver model revamp
by Robert Jarzmik 29 Aug '16

29 Aug '16

It all started in the pxa device-tree submission here : https://lkml.org/lkml/2016/2/25/965 It will be maintained in : git fetch https://github.com/rjarzmik/linux.git work/ac97 And now it transformed into this RFC, which would bring a ground for AC'97 devices closer to the linux device/driver model. The driving ideas are still the same, and I put them in [1] for memory. This is the second opus of the RFC. I'm intending to stop the RFC cycle here if possible and have a true PATCH v1 submission after this RFC v2 unless there is a deep design flaw uncovered. I took into account Mark's and Takashi's remarks, I hope I forgot none. All the changes should be documented in the first 2 patches mainly. I also added : - the AC97 link clock For now, bus code doesn't disable it in suspend and re-enable in resume, leaving the controller decide. I'm still pondering if for S2RAM (as opposed to runtime suspend), bus code should disable the clock. - the .h guards I'm not particularly happy with my naming even for v2, feel free to propose anything better, the codec.h is particularly ugly. - statics and namespace pollution I made more functions static, limiting further the namespace pollution. - Kconfig/Makefile layout change I get the feeling that the KConfig "select" flavor would have better been a "depends on" one. And yet I didn't find a good way to enforce it, because of the way sound/soc/codecs/Kconfig is designed, and I'm afraid to break the structure by doing a "depends on AC97_BUS_NEW" in WM9713 configuration. Let's have another review cycle, that will let me test this serie more thoroughly, especially the suspend/resume and the reset in the resume, which doesn't work, and requires me to test more deeply. I'll also test by removing the wm9713 change to see how robust the implementation is. Happy review. -- Robert Robert Jarzmik (7): ALSA: ac97: split out the generic ac97 registers ALSA: ac97: add an ac97 bus ASoC: add new ac97 bus support ASoC: wm9713: add ac97 new bus support ASoC: pxa: switch to new ac97 bus support ARM: pxa: mioa701 convert to the new AC97 bus ASoC: mioa701_wm9713: convert to new ac97 bus arch/arm/mach-pxa/mioa701.c | 12 +- include/sound/ac97/codec.h | 111 ++++++++++++ include/sound/ac97/compat.h | 21 +++ include/sound/ac97/controller.h | 80 +++++++++ include/sound/ac97/regs.h | 262 +++++++++++++++++++++++++++ include/sound/ac97_codec.h | 239 +------------------------ include/sound/pxa2xx-lib.h | 15 +- sound/Kconfig | 2 + sound/Makefile | 1 + sound/ac97/Kconfig | 18 ++ sound/ac97/Makefile | 8 + sound/ac97/ac97_core.h | 10 ++ sound/ac97/bus.c | 381 ++++++++++++++++++++++++++++++++++++++++ sound/ac97/codec.c | 15 ++ sound/ac97/snd_ac97_compat.c | 104 +++++++++++ sound/arm/Kconfig | 1 - sound/arm/pxa2xx-ac97-lib.c | 39 ++-- sound/soc/Kconfig | 4 + sound/soc/codecs/Kconfig | 1 + sound/soc/codecs/wm9713.c | 62 ++++++- sound/soc/pxa/Kconfig | 4 +- sound/soc/pxa/mioa701_wm9713.c | 4 +- sound/soc/pxa/pxa2xx-ac97.c | 20 ++- 23 files changed, 1132 insertions(+), 282 deletions(-) create mode 100644 include/sound/ac97/codec.h create mode 100644 include/sound/ac97/compat.h create mode 100644 include/sound/ac97/controller.h create mode 100644 include/sound/ac97/regs.h create mode 100644 sound/ac97/Kconfig create mode 100644 sound/ac97/Makefile create mode 100644 sound/ac97/ac97_core.h create mode 100644 sound/ac97/bus.c create mode 100644 sound/ac97/codec.c create mode 100644 sound/ac97/snd_ac97_compat.c -- 2.1.4 [1] RFC PATCH reminder: Amongst the driving ideas behind this RFC : - use device/driver model for AC'97 device/driver binding is based on vendor_id{1,2} - use auto-probe of the AC'97 bus to enumerate codecs and create devices - be compatible with previous platform_data model for codecs => this enables a smooth transition, where a codec (here wm9713) can be used either through platform_device or automatic discovery - struct snd_ac97 is not used This structure is really heavy, and doesn't represent an AC97 device, but rather an AC'97 codec internals IIUC. I think it's right place would be in include/sound/ac97/codec.h. This is also a problem for regmap adherence, hence the include/sound/ac97/compat.h. - a new AC'97 bus Kconfig is created This was done for a smooth transition ... let's see if it's a good idea. - split the AC'97 into : - the codec - the digital controller - the bus Amongst the things that are not all touched yet : - ac97_codec.c The generic AC'97 codec in sound/pci/ac97/ac97_codec.c has really a lot features, which are not at all PCI related. They could be transfered to sound/ac97, without the pci specific field. => this deserves a deep ahead thinking, which I'll do if the current approach is accepted by the communauty. The most important patch is 2/7 "ALSA: ac97: add an ac97 bus". This is the main evaluation point for the serie, the others are here so that I can test it all. Well, this is a long term effort, which might need a complete rewrite according to the comments it'll get. Let's expose it for comments and see how I can progress with it.

[alsa-devel] [PATCH v1 00/14] clk/mfd/ASoC/ARM: OMAP4/5: McPDM/twl6040 pdmclk support
by Peter Ujfalusi 15 Aug '16

15 Aug '16

Hi, Changes since v1: - Added Rob's Acked-by to patch 5 and 14 - Check the return value of clk_prepare_enable() calls in the last patch this is something I wanted to do for a long time... First of all: sorry for the cross domain series. I did tested alone all the domain patches and they are not causing any regression. When they come together we will have ability to control the pdmclk needed by McPDM. CLK patches: The driver was w/o DT support and needed some cleanup so we can use the driver. I have also renamed it to twl6040-pdmclk from twl6040-clk to be precise. MFD patches: The regmap_sync() was not working since the twl6040 does not support bulk access and now we are going to create the needed child for the pdmclk. ARM patches: Updatding the board DTS files and add the needed lines for the pdmclk. ASoC patches: The machine driver needs to select the twl6040-clk driver as it will be used by the omap-mcpdm. I needed to do some cleanup and add also suspend/resume support before adding the code for pdmclk handling since I don't want to keep the twl6040 powered on when the board is suspended. At the moment it is not possible to do true dynamic twl6040 power up/down due to pop noises, but I will be looking at that later. The driver in the future will fail if it is not able to get the pdmclk to avoid kernel crash (McPDM registers are not accessible when pdmclk is not available). I have tested the patches by domain and also in all (I hope) permutation they could be. I have not experienced any regression.

[alsa-devel] [PATCH 00/49] ASoC: add simple-card-core and standardize "simple" card
by Kuninori Morimoto 10 Aug '16

10 Aug '16

Hi Mark These are very big patch-set, but basically just cleanup for simple-card driver. Now, we have simple-card driver, but it is not simple today. I would like to cleanup this. And Renesas already have rsrc-card driver which is supporting DPCM, and it is based on simple-card. This measn rsrc-card and simple-card are very similar. Thus, I would like to share these code between rsrc-card and simple-card. This rsrc-card is only used from Renesas (actually, there is no upstream user, current user is only me, by local). But this is not Renesas special driver, I can say it is DPCM version of simple-card. I would like to open it for all of ALSA people. But, not merge simple-card <-> rsrc-card, to avoid diffcult future maintenance. Thus, rsrc-card will be simple-dpcm-audio-card, and we can maintenance both simple-card, and simple-dpcm-card. I'm not sure this is good nameing. And finally, we will need HDMI sound support which uses graph base probing. I know it needs more discussion with V4L2 people. But in my understanding, basically, we can reuse simple-card base feature/function on graph base driver somehow. I would like to standardize simple card style, and use/share it with graph driver too. It will be simple-graph-card ? I'm not sure. But I think we can share same code, and can avoid development from 0. These patch are for it. Basically, it pickups common function/feature from simple-card and rsrc-card, and standardize each feature/parse/init etc in simple-card-core. Because of this patch-set, "simple-card" become "simple" again :) I tested these (simple-card, rsrc-card) on my lager, Salvator boards. But I couldn't test some feature. I hope test it on many environment. 1) - 4) cleanup for these patch-set 5) - 19) pickuped common function/feature and put it to simple-card-core 20) - 32) use simple-card-core on simple-card 33) - 46) use simple-card-core on rsrc-card 47) - 49) rename rsrc-card to simple-dpcm-audio-card Kuninori Morimoto (49): 1) ASoC: simple-card: remove duplicate header 2) ASoC: rsrc-card: remove duplicate header 3) ASoC: rsrc-card: remove unused dai_num 4) ASoC: simple-card: platform also uses asoc_simple_card_sub_parse_of() 5) ASoC: add new simple-card-core.c 6) ASoC: simple-card-core: add asoc_simple_card_parse_tdm() 7) ASoC: simple-card-core: add asoc_simple_card_parse_dailink_name() 8) ASoC: simple-card-core: add asoc_simple_card_parse_card_name() 9) ASoC: simple-card-core: add asoc_simple_card_parse_card_prefix() 10) ASoC: simple-card-core: add asoc_simple_card_parse_card_widgets() 11) ASoC: simple-card-core: add asoc_simple_card_parse_card_widgets() 12) ASoC: simple-card-core: add asoc_simple_card_parse_clk() 13) ASoC: simple-card-core: add asoc_simple_card_parse_endpoint() 14) ASoC: simple-card-core: add asoc_simple_card_parse_dpcm() 15) ASoC: simple-card-core: add asoc_simple_card_init_jack() 16) ASoC: simple-card-core: add asoc_simple_card_init_dai() 17) ASoC: simple-card-core: add asoc_simple_card_canonicalize_dailink() 18) ASoC: simple-card-core: add asoc_simple_card_canonicalize_cpu() 19) ASoC: simple-card-core: add asoc_simple_card_clean_reference() 20) ASoC: simple-card: use asoc_simple_card_parse_daifmt() 21) ASoC: simple-card: use asoc_simple_card_parse_clk() 22) ASoC: simple-card: use asoc_simple_card_parse_endpoint() 23) ASoC: simple-card: use asoc_simple_card_parse_tdm() 24) ASoC: simple-card: use asoc_simple_card_parse_card_name() 25) ASoC: simple-card: use asoc_simple_card_parse_card_route() 26) ASoC: simple-card: use asoc_simple_card_parse_card_widgets() 27) ASoC: simple-card: use asoc_simple_card_parse_dailink_name() 28) ASoC: simple-card: use asoc_simple_card_init_jack() 29) ASoC: simple-card: use asoc_simple_card_init_dai() 30) ASoC: simple-card: use asoc_simple_card_canonicalize_dailink() 31) ASoC: simple-card: use asoc_simple_card_canonicalize_cpu() 32) ASoC: simple-card: use asoc_simple_card_clean_reference() 33) ASoC: rsrc-card: use asoc_simple_card_parse_daifmt() 34) ASoC: rsrc-card: use asoc_simple_card_parse_dailink_name() 35) ASoC: rsrc-card: use asoc_simple_dai instead of rsrc_card_dai 36) ASoC: rsrc-card: use asoc_simple_card_parse_clk() 37) ASoC: rsrc-card: use asoc_simple_card_parse_endpoint() 38) ASoC: rsrc-card: use asoc_simple_card_parse_card_name() 39) ASoC: rsrc-card: use asoc_simple_card_parse_card_prefix() 40) ASoC: rsrc-card: use asoc_simple_card_parse_dpcm() 41) ASoC: rsrc-card: use asoc_simple_card_parse_card_route() 42) ASoC: rsrc-card: use asoc_simple_card_parse_tdm() 43) ASoC: rsrc-card: use asoc_simple_card_init_dai() 44) ASoC: rsrc-card: use asoc_simple_card_canonicalize_cpu() 45) ASoC: rsrc-card: use asoc_simple_card_canonicalize_dailink() 46) ASoC: rsrc-card: use asoc_simple_card_clean_reference() 47) ASoC: rsrc-card: rename rsrc-card to simple-dpcm-card phase1 48) ASoC: rsrc-card: rename rsrc-card to simple-dpcm-card phase2 49) ASoC: rsrc-card: rename rsrc-card to simple-dpcm-card phase3 Documentation/devicetree/bindings/sound/renesas,rsrc-card.txt | 75 -------------- Documentation/devicetree/bindings/sound/simple-dpcm-card.txt | 79 +++++++++++++++ include/sound/simple_card.h | 11 +-- include/sound/simple_card_core.h | 106 ++++++++++++++++++++ sound/soc/generic/Kconfig | 10 ++ sound/soc/generic/Makefile | 4 + sound/soc/generic/simple-card-core.c | 409 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ sound/soc/generic/simple-card.c | 359 ++++++++++++------------------------------------------------------ sound/soc/generic/simple-dpcm-card.c | 330 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ sound/soc/sh/Kconfig | 5 - sound/soc/sh/rcar/Makefile | 3 - sound/soc/sh/rcar/rsrc-card.c | 529 -------------------------------------------------------------------------------------------------- 12 files changed, 999 insertions(+), 921 deletions(-)

Hi Mark These are v2 of simple-card cleanup patches. Main purpose of these patches are - cleanup simple-card - rename rsrc-card to simple-dpcm-card Main diff v1 <-> v2 are - remove duplicate header patch - rename simple-card-core.c -> simple-card-utils.c - remove dpcm function from simple-card-utils. - remove jack/pin/gpio/ function from simple-card-utils. - remove widgets/route function from simple-card-utils. I removed widgets/routing related function. it was very thin cosmetic functions. About jack/pin/gpio on simple-card, it is still have same method, but keeping it as static function. dpcm related function too, it is keeping static. 1) - 3) cleaup patch as prepare 4) - 14) simple-card-utils 15) - 24) simple-card 25) - 36) rsrc-card 37) - 39) rsrc-card -> simple-dpcm-card Kuninori Morimoto (39): 1) ASoC: rsrc-card: remove unused dai_num 2) ASoC: simple-card: use common PREFIX for each DT property 3) ASoC: simple-card: add new asoc_simple_jack and use it 4) ASoC: add new simple-card-utils.c 5) ASoC: simple-card-utils: add asoc_simple_card_parse_tdm() 6) ASoC: simple-card-utils: add asoc_simple_card_parse_dailink_name() 7) ASoC: simple-card-utils: add asoc_simple_card_parse_card_name() 8) ASoC: simple-card-utils: add asoc_simple_card_parse_card_prefix() 9) ASoC: simple-card-utils: add asoc_simple_card_parse_clk() 10) ASoC: simple-card-utils: add asoc_simple_card_parse_endpoint() 11) ASoC: simple-card-utils: add asoc_simple_card_init_dai() 12) ASoC: simple-card-utils: add asoc_simple_card_canonicalize_dailink() 13) ASoC: simple-card-utils: add asoc_simple_card_canonicalize_cpu() 14) ASoC: simple-card-utils: add asoc_simple_card_clean_reference() 15) ASoC: simple-card: use asoc_simple_card_parse_daifmt() 16) ASoC: simple-card: use asoc_simple_card_parse_clk() 17) ASoC: simple-card: use asoc_simple_card_parse_endpoint() 18) ASoC: simple-card: use asoc_simple_card_parse_tdm() 19) ASoC: simple-card: use asoc_simple_card_parse_card_name() 20) ASoC: simple-card: use asoc_simple_card_parse_dailink_name() 21) ASoC: simple-card: use asoc_simple_card_init_dai() 22) ASoC: simple-card: use asoc_simple_card_canonicalize_dailink() 23) ASoC: simple-card: use asoc_simple_card_canonicalize_cpu() 24) ASoC: simple-card: use asoc_simple_card_clean_reference() 25) ASoC: rsrc-card: use asoc_simple_card_parse_daifmt() 26) ASoC: rsrc-card: use asoc_simple_card_parse_dailink_name() 27) ASoC: rsrc-card: use asoc_simple_dai instead of rsrc_card_dai 28) ASoC: rsrc-card: use asoc_simple_card_parse_clk() 29) ASoC: rsrc-card: use asoc_simple_card_parse_endpoint() 30) ASoC: rsrc-card: use asoc_simple_card_parse_card_name() 31) ASoC: rsrc-card: use asoc_simple_card_parse_card_prefix() 32) ASoC: rsrc-card: use asoc_simple_card_parse_tdm() 33) ASoC: rsrc-card: use asoc_simple_card_init_dai() 34) ASoC: rsrc-card: use asoc_simple_card_canonicalize_cpu() 35) ASoC: rsrc-card: use asoc_simple_card_canonicalize_dailink() 36) ASoC: rsrc-card: use asoc_simple_card_clean_reference() 37) ASoC: rsrc-card: rename rsrc-card to simple-dpcm-card phase1 38) ASoC: rsrc-card: rename rsrc-card to simple-dpcm-card phase2 39) ASoC: rsrc-card: rename rsrc-card to simple-dpcm-card phase3 Documentation/devicetree/bindings/sound/renesas,rsrc-card.txt | 75 -------------- Documentation/devicetree/bindings/sound/simple-dpcm-card.txt | 79 +++++++++++++++ include/sound/simple_card.h | 11 +-- include/sound/simple_card_utils.h | 77 +++++++++++++++ sound/soc/generic/Kconfig | 10 ++ sound/soc/generic/Makefile | 4 + sound/soc/generic/simple-card-utils.c | 288 +++++++++++++++++++++++++++++++++++++++++++++++++++++ sound/soc/generic/simple-card.c | 424 ++++++++++++++++++++++++------------------------------------------------------ sound/soc/generic/simple-dpcm-card.c | 351 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ sound/soc/sh/Kconfig | 5 - sound/soc/sh/rcar/Makefile | 3 - sound/soc/sh/rcar/rsrc-card.c | 529 -------------------------------------------------------------------------------------------------- 12 files changed, 937 insertions(+), 919 deletions(-)
