[alsa-devel] [PATCH 5.6 00/71] ALSA: Use managed buffer allocation
by Takashi Iwai 10 Dec '19

10 Dec '19

Hi, we already got a PCM core extension in 5.5-rc1 for allocating / releasing the PCM buffers implicitly, so called managed buffer allocation mode. This patch set is to apply this new mode for the actual (non-ASoC) drivers. The patches for ASoC and the other subsystems will follow in later patch sets. Also, other PCM API changes will follow later, too. This won't change anything from the functional POV, but merely cleanups.

[alsa-devel] [PATCH for-5.6 0/2] usb:gadget: ALSA PCM API updates
by Takashi Iwai 10 Dec '19

10 Dec '19

Hi, this is a patch set to adapt the latest ALSA PCM API to staging drivers. Basically these are merely cleanups, as shown in diffstat, and there should be no functional changes. As the corresponding ALSA PCM API change is found in 5.5-rc1, please apply these on 5.5-rc1 or later. Or if you prefer, I can merge them through sound tree, too. Let me know. thanks, Takashi === Takashi Iwai (2): usb: gadget: u_audio: Use managed buffer allocation usb: gadget: u_audio: Drop superfluous ioctl PCM ops drivers/usb/gadget/function/u_audio.c | 19 ++----------------- 1 file changed, 2 insertions(+), 17 deletions(-) -- 2.16.4

[alsa-devel] [PATCH] ASoC: simple-card: Don't create separate link when platform is present
by Daniel Baluta 10 Dec '19

10 Dec '19

In normal sound case all DAIs are detected as CPU-Codec. simple_dai_link_of supports the presence of a platform but it counts it as a CPU DAI resulting in the creation of an extra link. Adding a platform property to a link description like: simple-audio-card,dai-link { cpu { sound-dai = <&sai1>; }; plat { sound-dai = <&dsp>; }; codec { sound-dai = <&wm8960>; } will result in the creation of two links: * sai1 <-> wm8960 * dsp <-> wm8960 which is obviously not what we want. We just want one single link with: * sai1 <-> wm8960 (and platform set to dsp).

[alsa-devel] [PATCH 00/55] ALSA: Support PCM sync_stop
by Takashi Iwai 10 Dec '19

10 Dec '19

Hi, this is the last episode of the trilogy of PCM enhancements for non-ASoC drivers. Basically this either adds the setup for card->sync_irq and removes the superfluous synchronize_irq() calls, or replaces the synchronization code with the new sync_irq PCM ops. For the explanation about PCM ssync_stop and card sync_irq, see the commits: 1e850beea2781d30418743dd99250291cef37919 ALSA: pcm: Add the support for sync-stop operation fabb26dcd104027b971c018275fe40f2ebe09ae3 ALSA: pcm: Add card sync_irq field thanks, Takashi === Takashi Iwai (55): ALSA: ad1889: Support PCM sync_stop ALSA: ali5451: Support PCM sync_stop ALSA: als300: Support PCM sync_stop ALSA: atiixp: Support PCM sync_stop ALSA: au88x0: Support PCM sync_stop ALSA: aw2: Support PCM sync_stop ALSA: azt3328: Support PCM sync_stop ALSA: bt87x: Support PCM sync_stop ALSA: ca0106: Support PCM sync_stop ALSA: cmipci: Support PCM sync_stop ALSA: cs4281: Support PCM sync_stop ALSA: cs46xx: Support PCM sync_stop ALSA: cs5535audio: Support PCM sync_stop ALSA: ctxfi: Support PCM sync_stop ALSA: echoaudio: Support PCM sync_stop ALSA: emu10k1: Support PCM sync_stop ALSA: ens137x: Support PCM sync_stop ALSA: es1938: Support PCM sync_stop ALSA: es1968: Support PCM sync_stop ALSA: fm801: Support PCM sync_stop ALSA: hda: Support PCM sync_stop ALSA: ice1712: Support PCM sync_stop ALSA: ice1724: Support PCM sync_stop ALSA: intel8x0: Support PCM sync_stop ALSA: korg1212: Support PCM sync_stop ALSA: lola: Support PCM sync_stop ALSA: maestro3: Support PCM sync_stop ALSA: nm256: Support PCM sync_stop ALSA: oxygen: Support PCM sync_stop ALSA: riptide: Support PCM sync_stop ALSA: rme32: Support PCM sync_stop ALSA: rme96: Support PCM sync_stop ALSA: rme9652: Support PCM sync_stop ALSA: sis7019: Support PCM sync_stop ALSA: sonicvibes: Support PCM sync_stop ALSA: trident: Support PCM sync_stop ALSA: via82xx: Support PCM sync_stop ALSA: ymfpci: Support PCM sync_stop ALSA: ad1816a: Support PCM sync_stop ALSA: es1688: Support PCM sync_stop ALSA: es18xx: Support PCM sync_stop ALSA: gus: Support PCM sync_stop ALSA: msnd: Support PCM sync_stop ALSA: opl3sa2: Support PCM sync_stop ALSA: opti9xx: Support PCM sync_stop ALSA: sb: Support PCM sync_stop ALSA: wavefront: Support PCM sync_stop ALSA: wss: Support PCM sync_stop ALSA: lx6464es: Support PCM sync_stop ALSA: mixart: Support PCM sync_stop ALSA: pcxhr: Support PCM sync_stop ALSA: vx222: Support PCM sync_stop ALSA: pdaudiocf: Support PCM sync_stop ALSA: vxpocket: Support PCM sync_stop ALSA: usb-audio: Support PCM sync_stop sound/isa/ad1816a/ad1816a_lib.c | 1 + sound/isa/es1688/es1688_lib.c | 1 + sound/isa/es18xx.c | 1 + sound/isa/gus/gus_main.c | 1 + sound/isa/gus/gusmax.c | 3 ++- sound/isa/gus/interwave.c | 1 + sound/isa/msnd/msnd_pinnacle.c | 1 + sound/isa/opl3sa2.c | 1 + sound/isa/opti9xx/opti92x-ad1848.c | 1 + sound/isa/sb/sb_common.c | 1 + sound/isa/wavefront/wavefront.c | 1 + sound/isa/wss/wss_lib.c | 1 + sound/pci/ad1889.c | 2 +- sound/pci/ali5451/ali5451.c | 3 +-- sound/pci/als300.c | 2 +- sound/pci/atiixp.c | 2 +- sound/pci/atiixp_modem.c | 2 +- sound/pci/au88x0/au88x0.c | 1 + sound/pci/aw2/aw2-alsa.c | 1 + sound/pci/azt3328.c | 2 +- sound/pci/bt87x.c | 2 +- sound/pci/ca0106/ca0106_main.c | 1 + sound/pci/cmipci.c | 1 + sound/pci/cs4281.c | 5 +---- sound/pci/cs46xx/cs46xx_lib.c | 1 + sound/pci/cs5535audio/cs5535audio.c | 2 +- sound/pci/ctxfi/cthw20k1.c | 4 +--- sound/pci/ctxfi/cthw20k2.c | 1 + sound/pci/echoaudio/echoaudio.c | 3 +++ sound/pci/emu10k1/emu10k1_main.c | 1 + sound/pci/emu10k1/emu10k1x.c | 1 + sound/pci/ens1370.c | 4 +--- sound/pci/es1938.c | 3 +++ sound/pci/es1968.c | 3 +-- sound/pci/fm801.c | 1 + sound/pci/hda/hda_intel.c | 4 +++- sound/pci/hda/hda_tegra.c | 4 +--- sound/pci/ice1712/ice1712.c | 2 +- sound/pci/ice1712/ice1724.c | 2 +- sound/pci/intel8x0.c | 4 +++- sound/pci/intel8x0m.c | 3 +++ sound/pci/korg1212/korg1212.c | 1 + sound/pci/lola/lola.c | 2 +- sound/pci/lx6464es/lx6464es.c | 1 + sound/pci/maestro3.c | 1 + sound/pci/mixart/mixart.c | 1 + sound/pci/nm256/nm256.c | 2 ++ sound/pci/oxygen/oxygen_lib.c | 2 +- sound/pci/pcxhr/pcxhr.c | 1 + sound/pci/riptide/riptide.c | 1 + sound/pci/rme32.c | 1 + sound/pci/rme96.c | 1 + sound/pci/rme9652/hdsp.c | 1 + sound/pci/rme9652/hdspm.c | 1 + sound/pci/rme9652/rme9652.c | 1 + sound/pci/sis7019.c | 1 + sound/pci/sonicvibes.c | 1 + sound/pci/trident/trident_main.c | 1 + sound/pci/via82xx.c | 3 +-- sound/pci/via82xx_modem.c | 3 +-- sound/pci/vx222/vx222.c | 1 + sound/pci/ymfpci/ymfpci_main.c | 1 + sound/pcmcia/pdaudiocf/pdaudiocf.c | 1 + sound/pcmcia/vx/vxpocket.c | 1 + sound/usb/pcm.c | 37 +++++++++++++++++++++++++------------ 65 files changed, 101 insertions(+), 47 deletions(-) -- 2.16.4

Right, I meant extern1 the parent of clk_out_1, sorry for the confusion. So when clk_out_1 (child) is enabled, extern1 (parent) is enabled as well. I'll take a closer look at the other email tomorrow.

[alsa-devel] [PATCH] ASoC: core: only flush inited work during free
by Curtis Malainey 09 Dec '19

09 Dec '19

There are many paths to soc_free_pcm_runtime which can both have and have not yet inited the workqueue yet. When we flush the queue when we have not yet inited the queue we cause warnings to be printed. An example is soc_cleanup_card_resources which is called by snd_soc_bind_card which has multiple failure points before and after soc_link_init -> soc_new_pcm which is where the queue is inited.

There is no need to store the inverted DALIGN values in the table, as they can easily be calculated at run-time.

[alsa-devel] [PATCH] ASoC: ti: davinci-mcasp: Improve the sysclk selection
by Peter Ujfalusi 09 Dec '19

09 Dec '19

When McASP is master the bclk can be generated from two main source: AUXCLK: functional clock for McASP or AHCLK: from external source or internal mux in dra7x family With this patch it is possible to select between the two source. The patch is not breaking existing machine drivers since historically the clk_id was ignored and left as 0 in all cases. When output clock is configured - which can be only the AHCLK, we select the AUXCLK as source for the internal HCLK. In this case the HCLK rate is the same as the output clock.

[alsa-devel] [PATCH] ASoC: SOF: Intel: hda: solve MSI issues by merging ipc and stream irq handlers
by Pierre-Louis Bossart 09 Dec '19

09 Dec '19

From: Bard Liao <yung-chuan.liao(a)linux.intel.com> The existing code uses two handlers for a shared edge-based MSI interrupts. In corner cases, interrupts are lost, leading to IPC timeouts. Those timeouts do not appear in legacy mode. This patch merges the two handlers and threads into a single one, and simplifies the mask/unmask operations by using a single top-level mask (Global Interrupt Enable). The handler only checks for interrupt sources using the Global Interrupt Status (GIS) field, and all the actual work happens in the thread. This also enables us to remove the use of spin locks. Stream events are prioritized over IPC ones. This patch was tested with HDaudio and SoundWire platforms, and all known IPC timeout issues are solved in MSI mode. The SoundWire-specific patches will be provided in follow-up patches, where the SoundWire interrupts are handled in the same thread as IPC and stream interrupts.

[alsa-devel] [PATCH v2] ASoC: hdmi-codec: re-introduce mutex locking again
by Jerome Brunet 09 Dec '19

09 Dec '19

The dai codec needs to ensure that on one dai is used at any time. This is currently protected by bit atomic operation. With this change, it done with a mutex instead. This change is not about functionality or efficiency. It is done with the hope that it help maintainability in the future.

[alsa-devel] [PATCH v2 00/13] ASoC: SOF: initial cleanup for DT and multi-client support
by Pierre-Louis Bossart 09 Dec '19

09 Dec '19

This series does not add new functionality but introduces a better code partition to support machine drivers in Device Tree, as well as a 'componentization' of the PCM/topology parts needed for multi-client support. This cleanup was merged in the SOF tree and tested extensively with no regressions identified. Thanks Ranjani and Daniel for combining your proposals in a single change. Changes since v1: Rebased on top of Jaroslav's HDaudio changes (added in this series as discussed with Mark) Daniel Baluta (2): ASoC: SOF: Make creation of machine device from SOF core optional ASoC: SOF: Remove unused drv_name in sof_pdata Jaroslav Kysela (3): ASoC: intel/skl/hda - export number of digital microphones via control components ASoC: Intel - use control components to describe card config ASoC: Intel - do not describe I/O configuration in the long card name Ranjani Sridharan (8): ASoC: SOF: topology: remove snd_sof_init_topology() ASoC: SOF: core: modify the signature for snd_sof_create_page_table ASoC: SOF: core: move check for runtime callbacks to core ASoC: SOF: Introduce default_fw_filename member in sof_dev_desc ASoC: SOF: partition audio-related parts from SOF core ASoC: SOF: intel: hda: Modify signature for hda_codec_probe_bus() ASoC: SOF: remove nocodec_fw_filename ASoC: SOF: nocodec: Amend arguments for sof_nocodec_setup() include/sound/sof.h | 8 +- sound/soc/intel/boards/Kconfig | 13 + sound/soc/intel/boards/bytcht_es8316.c | 13 +- sound/soc/intel/boards/bytcr_rt5640.c | 10 + sound/soc/intel/boards/bytcr_rt5651.c | 22 +- sound/soc/intel/boards/skl_hda_dsp_generic.c | 8 + sound/soc/sof/Makefile | 2 +- sound/soc/sof/control.c | 55 +-- sound/soc/sof/core.c | 244 +--------- sound/soc/sof/intel/apl.c | 7 + sound/soc/sof/intel/bdw.c | 33 ++ sound/soc/sof/intel/byt.c | 45 ++ sound/soc/sof/intel/cnl.c | 7 + sound/soc/sof/intel/hda-codec.c | 16 +- sound/soc/sof/intel/hda-dai.c | 1 + sound/soc/sof/intel/hda-pcm.c | 4 +- sound/soc/sof/intel/hda-stream.c | 1 + sound/soc/sof/intel/hda.c | 228 ++++++---- sound/soc/sof/intel/hda.h | 8 +- sound/soc/sof/ipc.c | 16 +- sound/soc/sof/nocodec.c | 12 - sound/soc/sof/ops.h | 34 ++ sound/soc/sof/pcm.c | 131 +++--- sound/soc/sof/pm.c | 219 +-------- sound/soc/sof/sof-acpi-dev.c | 39 +- sound/soc/sof/sof-audio.c | 445 +++++++++++++++++++ sound/soc/sof/sof-audio.h | 211 +++++++++ sound/soc/sof/sof-of-dev.c | 24 +- sound/soc/sof/sof-pci-dev.c | 47 +- sound/soc/sof/sof-priv.h | 202 +-------- sound/soc/sof/topology.c | 374 ++++++++-------- sound/soc/sof/trace.c | 4 +- sound/soc/sof/utils.c | 60 +++ 33 files changed, 1380 insertions(+), 1163 deletions(-) create mode 100644 sound/soc/sof/sof-audio.c create mode 100644 sound/soc/sof/sof-audio.h -- 2.20.1

I2S could use assigned-clocks, but probably it's not really necessary and predefined configuration in the clk driver is good enough. At least PLLA doesn't need to be always-enabled since audio drivers enable it when necessary.

[alsa-devel] Headset button mapping in the kernel
by Curtis Malainey 06 Dec '19

06 Dec '19

Hello ALSA Devs, I am looking to get some feedback/ideas on a possible change to headset button mapping. Locally we are carrying patches that implement the mappings in the machine driver (which we understand you do not want upstream.) We are looking to see if we can add a new API (something like a sysfs path potentially) to have userspace pass in the mapping, if it chooses to, so the mapping can still be done in the kernel. That way we can carry just the config locally and remove some of the kernel patches we are carrying locally. Thanks. Curtis

Hi Mark Cc Pierre-Louis, Takashi-san Currently, I'm focusing to ASoC cleanup / balance-up. But, it found more unbalance issue, and Intel noticed about it. These patches fix dai_link remove issue on topology. I want to get Acked-by or Reviewed-by from Takashi-san for 2) patch if possible. These are already tested by Intel CI, and all issues were solved. (https://github.com/thesofproject/linux/pull/1504) Extra Tested-by / Reviewed-by are very welcome from Intel Kuninori Morimoto (2): 1) ASoC: soc-component: tidyup snd_soc_pcm_component_new/free() parameter 2) ASoC: soc-pcm: remove soc_pcm_private_free() include/sound/soc-component.h | 4 ++-- sound/soc/soc-component.c | 8 +++----- sound/soc/soc-core.c | 19 +++++++++++-------- sound/soc/soc-pcm.c | 12 +----------- 4 files changed, 17 insertions(+), 26 deletions(-) -- 2.7.4

[alsa-devel] [PATCH v14 6/7] ASoC: amd: Added ACP3x system resume and runtime pm
by Ravulapati Vishnu vardhan rao 05 Dec '19

05 Dec '19

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.

This means that you encounter model-specific issue as regression I didn't realized. For my information, would you please get output from nodes on procfs? * /proc/asound/cardX/firewire/clock * /proc/asound/cardX/firewire/firmware * /proc/asound/cardX/firewire/formation Additionally, please install 'gir1.2-hinawa-2.0' package, then clone below remote repository: * https://github.com/takaswie/hinawa-utils This repository includes two scripts to get information from the device: * hinawa-bebob-parser * hinawa-bebob-connection-cui When your device is detected as sound card '2' and your device is also detected as '/dev/fw1', execute below: $ ./hinawa-bebob-connection-cui 2 graph-connections $ ./hinawa-bebob-parser 1 2 > At startup it lights green ok, but no sound is playable, then the > lights turn orange (like it is when it's not working), I hear a > "relay sound" (a electric clic of a relay), then, the Saffire LE > disapears from the sound menu in Ubuntu sound menu. Once your device is detected and ALSA bebob driver bound to it, pulseaudio detects it and start PCM substream to get capabilities of the device. In your case, the PCM substream is corrupted by the discontinuity. Then pulseaudio give up to use the device. As a result, sound menu drops entry of the device. I guess that the color of LED corresponds to the packet streaming.

[alsa-devel] [ANNOUNCE] fcplay: compressed audio test utility
by Vinod Koul 05 Dec '19

05 Dec '19

Hello, I have forked the cplay test app into fcplay which is a different repo [1] licensed as LGPLv2.1. The reason for fork was me getting sick of seeing the tool miss sync word for mp3 and no support for other formats which I wanted to test. But I was lazy to start exploring all media formats and write a parser for them so I have used libavcodec to the job for me which is GPL. The fcplay links to libavcodec to get compressed audio parameters and then uses tinycompress to send data to sound card. It supports mp3 (no more complaints about sync words) and Flac. I will add more formats, wma etc are in the list along with gapless audio playback and support for new changes coming to gapless audio playback as discussed in audio meeting at Lyon. As usual patches are welcome. Jaroslav, can we add to alsa-project github as well? Thanks -- ~Vinod

[alsa-devel] fcplay: initial addition
by GitHub pull_request - opened 05 Dec '19

05 Dec '19

alsa-project/tinycompress pull request #3 was opened from vinodkoul: This tool was forked from tinycompress cplay. The fork was required due to this linking against libavcodec which is GPL. This uses libav APIs to parse the compressed files and send the audio stream to compressed device using tinycompress APIs Right now it supports only playback on MP3 (no problems now not finding sync word) and flac files.

[alsa-devel] [PATCH] ALSA: pcm: oss: Avoid potential buffer overflows
by Takashi Iwai 04 Dec '19

04 Dec '19

syzkaller reported an invalid access in PCM OSS read, and this seems to be an overflow of the internal buffer allocated for a plugin. Since the rate plugin adjusts its transfer size dynamically, the calculation for the chained plugin might be bigger than the given buffer size in some extreme cases, which lead to such an buffer overflow as caught by KASAN. Fix it by limiting the max transfer size properly by checking against the destination size in each plugin transfer callback.

[alsa-devel] [PATCH v2] ASoC: core: Init pcm runtime work early to avoid warnings
by Curtis Malainey 04 Dec '19

04 Dec '19

There are cases where we fail before we reach soc_new_pcm which would init the workqueue. When we fail we attempt to flush the queue which generates warnings from the workqueue subsystem when we have not inited the queue. Solution is to use a proxy function to get around this issue.

[alsa-devel] [PATCH] ASoC: snd-sof-pci - add model parameter and pass it to HDA codec driver
by Jaroslav Kysela 03 Dec '19

It may be useful to pass the specific model to the generic HDA codec routines like the legacy HDA driver (snd-hda-intel) allows. The model name "sofbus" is tricky anyway.

[alsa-devel] Integrating Texes Instruments PCM1860 ADC
by Umar Dockrat 03 Dec '19

03 Dec '19

Good Day, I have been struggling with the integration of a PCM1860 ADC for audio recording. I have created a "sound card" board that contains both a PCM5102A (DAC) and PCM1860 (ADC). The main processor is an Omega Onion 2 which is based on MediaTek MT7688 SoC device. I am struggling with creating the device tree as the Kernel currently has reference to the PCM186X where X is 2,3,4 or 5 but not the more simple PCM1860. The difference between the PCM1860 and the PCM186X is that the PCM1860 does not have I2C control and is HW configured using pull up/down. https://www.kernel.org/doc/Documentation/devicetree/bindings/sound/pcm186x.… I have tried multiple device tree setup's and have only got the DAC working when configured in isolation, as soon as I add any reference to the ADC then both DAC and ADC are not recognised. This DTSI allows the DAC to function https://pastebin.com/z9H67DHd There are my attempts at including the DAC and ADC: https://pastebin.com/RLsKNsiR https://pastebin.com/rmJVcCz1 Please can someone assist with the correct way to integrate this ADC device? Any suggestions on how to properly debug this further is also really appreciated. Thanks, UFD

[alsa-devel] a52 plugin + ffmpeg with libswresample
by Giovanni Harting 03 Dec '19

03 Dec '19

Hello, I'm working on restoring functionality to the a52 plugin. ALSA build with ffmpeg without (deprecated) libavresample does not build this plugin, since libavresample is missing. Archlinux for example does not build with libavresample anymore [1], therefore a52 is missing in alsa-plugins builds since that change happened. I ported rate-lav to libswresample, which seems to work well after a month of daily use. The oddity is that a config file (asoundrc, [2]), that worked fine with alsa-lib 1.1.6, does not work with 1.1.7+. I could not find a change that causes this. I traced it down to _snd_pcm_rate_open() in pcm/pcm_rate.c, where keywords from within pcm {} are passed into, where it fails with "Unknown field card" (for example). I worked around it by filtering out all keywords [3], but that feels a little unclean. Is there a proper way to fix this? I'm not familiar with ALSA's config parsing. I'll submit patches for both once I figured out how to fix this. [1] https://bugs.archlinux.org/task/60586 [2] pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 bitrate 640 channels 6 card $CARD } rate 48000 format S16_LE } } [3] if (strcmp(id, "bitrate") == 0 || strcmp(id, "rate") == 0 || strcmp(id, "card") == 0 || strcmp(id, "channels") == 0 || strcmp(id, "format") == 0) { continue; }

[alsa-devel] [PATCH alsa-lib] ucm: Do not fail to parse configs on cards with an empty CardComponents lists
by Hans de Goede 03 Dec '19

03 Dec '19

Since the UCM profiles for all Bay- and Cherry-Trail SST cards have been moved over to UCM2, parsing them fails with: ALSA lib ucm_subs.c:220:(uc_mgr_get_substituted_value) variable '${CardComponents}' is not defined in this context! This completely breaks audio support on all Bay- and Cherry-Trail devices. This is caused by these non-SOF ASoC using cards having an empty CardComponents list. Which in itself is fine, but is rejected by the ucm_subs.c code. This commit changes the ucm_subs code to accept an empty string as a valid value for CardComponents restoring audio functionality on these boards.

[alsa-devel] [PATCH 0/3] Add NAU8812 support
by Marco Felsch 03 Dec '19

03 Dec '19

Hi, this small series adds the documentation and support for the nau8812 devices. The exisiting nau8810 driver can handle both devices so we only need to add the dt-bindings and inform the user by adapting the Kconfig entry. Futhermore the series adds the support for the aux-port control. @John Hsu Please can you verify that register accesses to the aux-port control bits don't affect the nau8810 devices? I don't have such a device but the documentations says that those register fields are just '0'ed. So I assume the nau8810 devices ignore such writes.

[alsa-devel] [PATCH] ASoC: core: Init pcm runtime work early to avoid warnings
by Curtis Malainey 03 Dec '19

03 Dec '19

There are cases where we fail before we reach soc_new_pcm which would init the workqueue. When we fail we attempt to flush the queue which generates warnings from the workqueue subsystem when we have not inited the queue. Solution is to use a proxy function to get around this issue.

[alsa-devel] [PATCH] ASoC: da7219: remove SRM lock check retry
by Brent Lu 03 Dec '19

03 Dec '19

For platforms not able to provide WCLK in the PREPARED runtime state, it takes 400ms for codec driver to print the message "SRM failed to lock" in the da7219_dai_event() function which is called when DAPM widgets are powering up. The latency penalty to audio input/output is too much so the retry (8 times) and delay (50ms each retry) are removed. Another reason is current Cold output latency requirement in Android CDD is 500ms but will be reduced to 200ms for 2021 platforms. With the 400ms latency it would be difficult to pass the Android CTS test.

[alsa-devel] [PATCH] ALSA: hda: hdmi - Keep old slot assignment behavior for Intel platforms
by Takashi Iwai 03 Dec '19

03 Dec '19

The commit 609f5485344b ("ALSA: hda: hdmi - preserve non-MST PCM routing for Intel platforms") tried to restore the old behavior wrt assignment of the PCM slot for Intel platforms, but this didn't do it right. As found in the later discussion, even on non-MST, a positive pipe id is passed, which is equivalent with dev_id on Intel. This patch reverts the previous attempt and applies a simpler workaround instead. Actually, for Intel platforms, we can handle as if per_pin->dev_id=0, assign the primary slot at the first try. This assures the compatible behavior with the previous versions regarding the slot assignment.

Add additional check in hdmi_find_pcm_slot() to not return a pcm index that points to unallocated pcm. This could happen if codec driver is set up in codec->mst_no_extra_pcms mode.

Hi, I'm not subscribed to the list. I was looking for uses of SCHED_IDLE in software in general when I stubled upon this. Although I have no personal interest in asla development, I thought it would be nice to report it here. alsa-project/alsa-utils commit 611249ae26f435429dbe1894e210704a723ee277 says: alsactl: add --nice and --sched-idle options The state management can run at low priority, add --nice and --sched-idle options to set the scheduler. Everywhere in the code it says SCHED_IDLE *except* for the actual call to sched_setscheduler() which instead sets the policy to SCHED_RR. I have looked twice to see that I don't miss anything obvious, and suspect this is an error, or that there should be a comment that explains this oddity. Kind regards, Tommy

[alsa-devel] simple card, asymetrical configuration
by Michael Walle 03 Dec '19

03 Dec '19

Hi Kuninori, there seems to be a problem in the simple-card using the following device tree fragment: sound { compatible = "simple-audio-card"; simple-audio-card,format = "i2s"; [snip] simple-audio-card,bitclock-master = <&dailink0_master>; simple-audio-card,frame-master = <&dailink0_master>; simple-audio-card,cpu@0 { sound-dai = <&sai6>; }; simple-audio-card,cpu@1 { sound-dai = <&sai5>; }; dailink0_master: simple-audio-card,codec { sound-dai = <&wm8904>; }; }; Just for the background, I have hardware with the LS1028A which only have unidirectional SAIs. But two of those SAIs (one for playback and one for capture) are connected to one codec (with a shared bit and frame clock). So I thought the example in the simple-card bindings makes sense for my case. Although I don't really know what "(Mixing)" means. Nevertheless, using the fragment above, the kernel oopses or fails to probe the hardware. I've traced that back to the following: - the count is correct: the kernel reports "link 2, dais 3, ccnf 0". please note the 3 dais here. - but simple_dai_link_of() will always "allocate" two dais from the pool: cpu_dai = dai_props->cpu_dai = &priv->dais[li->dais++]; codec_dai = dai_props->codec_dai = &priv->dais[li->dais++]; While this still works for the first link, the second one will fail because codec_dai will not be valid. Btw, converting that to two explicit dai-link nodes, the dai count will be 4 and it will work. Is my use case correct or should I use the two explicit dai-link nodes? But in any case there seems to be a bug in simple-card. -michael

[alsa-devel] Integrating Texes Instruments PCM1860 ADC
by Umar Dockrat 02 Dec '19

02 Dec '19

Good Day, I have been struggling with the integration of a PCM1860 ADC for audio recording. I have created a "sound card" board that contains both a PCM5102A (DAC) and PCM1860 (ADC). The main processor is an Omega Onion 2 which is based on MediaTek MT7688 SoC device. I am struggling with creating the device tree as the Kernel currently has reference to the PCM186X where X is 2,3,4 or 5 but not the more simple PCM1860. The difference between the PCM1860 and the PCM186X is that the PCM1860 does not have I2C control and is HW configured using pull up/down. https://www.kernel.org/doc/Documentation/devicetree/bindings/sound/pcm186x.… I have tried multiple device tree setup's and have only got the DAC working when configured in isolation, as soon as I add any reference to the ADC then both DAC and ADC are not recognised. This DTSI allows the DAC to function https://pastebin.com/z9H67DHd There are my attempts at including the DAC and ADC: https://pastebin.com/RLsKNsiR https://pastebin.com/rmJVcCz1 Please can someone assist with the correct way to integrate this ADC device? Any suggestions on how to properly debug this further is also really appreciated. Thanks, UFD

[alsa-devel] regression: aplay -L missing pulse in 1.2.1
by GitHub issues - opened 01 Dec '19

01 Dec '19

alsa-project/alsa-plugins issue #3 was opened from higuita: Before 1.2, `aplay -L` showed a pulse pcm. After the commit https://github.com/alsa-project/alsa-plugins/commit/b0f9c353c7cc9cffb77e7a7… pulse is missing from the pcm list. This may break some apps, war thunder (used fmod) game stopped seeing pulse and only tried to use alsa directly if i comment out the below line in /usr/share/alsa/alsa.conf.d/50-pulseaudio.conf `@args [ DEVICE ]` `aplay -L` show again the pulse pcm another workaround is to add this to the `/etc/asound.conf` : ``` pcm.!pulse { type pulse hint { show on description "PulseAudio Sound Server" } } ``` Issue URL : https://github.com/alsa-project/alsa-plugins/issues/3 Repository URL: https://github.com/alsa-project/alsa-plugins

[alsa-devel] More USB audio quirks
by Damien Zammit 30 Nov '19

30 Nov '19

Hi all, I asked on a forum for people to post their lsusb -vv output for usb audio devices that were not being detected correctly, and I tried to write some quirks for them. I don't know the current status on whether support has been added, but please someone take a look at: https://discourse.ardour.org/t/providing-assistance-to-devs-for-new-alsa-us… for some more output and my attempts at writing new quirks. Apologies if this is now out of date. Damien

[alsa-devel] [PATCH] ALSA: hda/realtek - Fix inverted bass GPIO pin on Acer 8951G
by Takashi Iwai 28 Nov '19

28 Nov '19

We've added the bass speaker support on Acer 8951G by the commit 00066e9733f6 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems that the GPIO pin was wrongly set: while the commit turns off the bit to power up the amp, the actual hardware reacts other way round, i.e. GPIO bit on = amp on. So this patch fixes the bug, turning on the GPIO bit 0x02 as default. Since turning on the GPIO bit can be more easily managed with alc_setup_gpio() call, we simplify the quirk code by integrating the GPIO setup into the existing alc662_fixup_aspire_ethos_hp() and dropping the whole ALC669_FIXUP_ACER_ASPIRE_ETHOS_SUBWOOFER quirk.

[alsa-devel] Surround speaker connection on Acer 8951G
by Sergey 'Jin' Bostandzhyan 28 Nov '19

28 Nov '19

Hi, I am not sure if this is the right place to ask or if I should just submit a bugreport, but you guys helped me out with a similar problem about 10 years ago, so I'll try here first. If I'm wrong here, then I apologize, just let me know. I have an Acer Aspire Ethos 8951G notebook which has 6 built in speakers for 5.1 surround sound, it's a Realtek ALC669X. The problem is that only two speakers are recognized by default. I tried fiddling around with hdajackretast and it does make a difference, but I somehow could not find a step-by-step approach on how to figure out what is what and how to map everything correctly, so some guidance would be very much appreciated. I even ended up in situations where I got channels supporting only mute which would influence muting of other channels, I really got lost there.. Here's my alsa-info output: http://alsa-project.org/db/?f=3adde87164f5fc349c3c78b211ee63e416ebf10b It would be great if we could figure it out and make it work by default. Basically that's what we did 10 years ago, back then I had an Acer Aspire 8920G with a ALC889 which had the same problem that got fixed by you and these days it just works out of the box :) Kind regards, Jin

[alsa-devel] [PATCH] ASoC: AMD: Enable clk in startup intead of hw_params
by Yu-Hsuan Hsu 28 Nov '19

28 Nov '19

Some usages only call startup and shutdown without setting hw_params (e.g. arecord --dump-hw-params). If we don't enable clk in startup, it will cause ref count error because the clk will be disabled in shutdown. For this reason, we should move enabling clk from hw_params to startup. In addition, the hw_params is fixed in this driver(48000 rate, 2 channels, S16_LE format) so we don't need to change the clk rate after the hw_params is set.

[alsa-devel] [PATCH v3] ALSA: hda: hdmi - fix regression in connect list handling
by Kai Vehmanen 28 Nov '19

28 Nov '19

Fix regression in how intel_haswell_fixup_connect_list() results are used in hda_read_pin_conn(). Use of snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses the cache and thus also bypasses the overridden pin connection list.

[alsa-devel] [PATCH v2 00/12] treewide: break dependencies on x86's RM header
by Sean Christopherson 27 Nov '19

27 Nov '19

x86's asm/realmode.h, which defines low level structures, variables and helpers used to bring up APs during SMP boot, ends up getting included in practically every nook and cranny of the kernel because the address used by ACPI for resuming from S3 also happens to be stored in the real mode header, and ACPI bleeds the dependency into its widely included headers. As a result, modifying realmode.h for even the most trivial change to the boot code triggers a full kernel rebuild, which is frustrating to say the least as it some of the most difficult code to get exactly right *and* is also some of the most functionally isolated code in the kernel. To break the kernel's widespread dependency on realmode.h, add a wrapper in the aforementioned ACPI S3 code to access the real mode header instead of derefencing the header directly in asm/acpi.h and thereby exposing it to the world via linux/acpi.h. v2: - Rebased on tip/x86/cleanups, commit b74374fef924 ("x86/setup: Enhance the comments"). - Use acpi_get_wakeup_address() as new function name. [Boris and Pavel] - Capture acpi_get_wakeup_address() in a local address. [Pavel] - Collect acks. I didn't add Rafael's acks on patches 11 and 12 due to the above changes. - Explicitly call out the removal of <asm/realmode.h> from <asm/acpi.h> in patch 12. [Ingo] - Remove superfluous Fixes: tags. [Ard] Patch Synopsis: - Patches 01-09 fix a variety of build errors that arise when patch 12 drops realmode.h from asm/acpi.h. Most of the errors are quite absurb as they have no relation whatsoever to x86's RM boot code, but occur because realmode.h happens to include asm/io.h. - Patch 10 removes a spurious include of realmode.h from an ACPI header. - Patches 11 and 12 implement the wrapper and move it out of acpi.h. Sean Christopherson (12): x86/efi: Explicitly include realmode.h to handle RM trampoline quirk x86/boot: Explicitly include realmode.h to handle RM reservations x86/ftrace: Explicitly include vmalloc.h for set_vm_flush_reset_perms() x86/kprobes: Explicitly include vmalloc.h for set_vm_flush_reset_perms() perf/x86/intel: Explicitly include asm/io.h to use virt_to_phys() efi/capsule-loader: Explicitly include linux/io.h for page_to_phys() virt: vbox: Explicitly include linux/io.h to pick up various defs vmw_balloon: Explicitly include linux/io.h for virt_to_phys() ASoC: Intel: Skylake: Explicitly include linux/io.h for virt_to_phys() x86/ACPI/sleep: Remove an unnecessary include of asm/realmode.h ACPI/sleep: Convert acpi_wakeup_address into a function x86/ACPI/sleep: Move acpi_get_wakeup_address() into sleep.c, remove <asm/realmode.h> from <asm/acpi.h> arch/ia64/include/asm/acpi.h | 5 ++++- arch/ia64/kernel/acpi.c | 2 -- arch/x86/events/intel/ds.c | 1 + arch/x86/include/asm/acpi.h | 3 +-- arch/x86/kernel/acpi/sleep.c | 11 +++++++++++ arch/x86/kernel/acpi/sleep.h | 2 +- arch/x86/kernel/ftrace.c | 1 + arch/x86/kernel/kprobes/core.c | 1 + arch/x86/kernel/setup.c | 1 + arch/x86/platform/efi/quirks.c | 1 + drivers/acpi/sleep.c | 3 +++ drivers/firmware/efi/capsule-loader.c | 1 + drivers/misc/vmw_balloon.c | 1 + drivers/virt/vboxguest/vboxguest_core.c | 1 + drivers/virt/vboxguest/vboxguest_utils.c | 1 + sound/soc/intel/skylake/skl-sst-cldma.c | 1 + 16 files changed, 30 insertions(+), 6 deletions(-) -- 2.24.0

[alsa-devel] [PATCH] ALSA: aloop: Avoid pointer dereference before null-check
by Andrew Gabbasov 27 Nov '19

27 Nov '19

Static analysis tools (cppcheck and PVS Studio) report an error in loopback_snd_timer_period_elapsed() regarding dpcm_play pointer dereference earlier than its null-check. And although this is a result of a formal check, and the pointer correctness is also protected by having a corresponding bit set in the "running" mask, re-ordering of the lines can imake the code even formally correct and eliminate those static analysis error reports.

[alsa-devel] Multiple LADSPA plugin paths when some of them error
by jimmy＠spalge.com 27 Nov '19

27 Nov '19

Having multiple lookup paths for ladspa plugins is supported by separating them with ":" in a "path" directive on the pcm definition in asoundrc or the LADSPA_PATH environment variable. But if there is an error encountered while looking for the plugin in one of the earlier paths than later ones won't be checked. My use case is that I have a mixed architecture system (moving from 32 to 64 bit) and I need applications of both architectures to do sound stuff. Since the dlopen will always fail for one of them it doesn't quite work as-is (I've patched it locally sufficient for my needs). I think snd_pcm_ladspa_look_for_plugin in src/pcm/pcm_ladspa.c should be changed to not return on errors in the loop but just log a message and proceed.

[alsa-devel] Converting a non BE to BE inside soc_check_tplg_fes
by Daniel Baluta 27 Nov '19

27 Nov '19

Hi all, I am trying how a non-BE link is converted to a BE link inside soc_check_tplg_fes. soc_check_tplg_fes => for all components that have ignore_machine setup to card name => dai_link->platforms->name = component->name; => dai_link->no_pcm = 1; But the thing is that the link is a true non-DPCM link, than fields like dpcm_playback/dpcm_capture are not set and playback/record substreams are no created. The question is: is this supposed to be working with non-DPCM links?

[alsa-devel] [PATCH 0/4] add runtime pm support for AMD display audio
by Alex Deucher 26 Nov '19

26 Nov '19

These patches were originally part of a larger set of patches to enabled runtime pm support on the GPU side[1]. However, the patches are useful on their own there are really no dependencies, other than the fact that you need both for runtime pm to kick in on the GPU side. The GPU side will be landing for 5.6; I'd like to land the audio side as well.

[alsa-devel] [PATCH 00/12] treewide: break dependencies on x86's RM header
by Sean Christopherson 26 Nov '19

26 Nov '19

x86's asm/realmode.h, which defines low level structures, variables and helpers used to bring up APs during SMP boot, ends up getting included in practically every nook and cranny of the kernel because the address used by ACPI for resuming from S3 also happens to be stored in the real mode header, and ACPI bleeds the dependency into its widely included headers. As a result, modifying realmode.h for even the most trivial change to the boot code triggers a full kernel rebuild, which is frustrating to say the least as it some of the most difficult code to get exactly right *and* is also some of the most functionally isolated code in the kernel. To break the kernel's widespread dependency on realmode.h, add a wrapper in the aforementioned ACPI S3 code to access the real mode header instead of derefencing the header directly in asm/acpi.h and thereby exposing it to the world via linux/acpi.h. Build tested on x86 with allyesconfig and allmodconfig, so hopefully there aren't more build issues lurking, but at this point it wouldn't surprise me in the least if this somehow manages to break the build. Based on tip/master, commit ceceaf1f12ba ("Merge branch 'WIP.x86/cleanups'"). Patch Synopsis: - Patches 01-09 fix a variety of build errors that arise when patch 12 drops realmode.h from asm/acpi.h. Most of the errors are quite absurb as they have no relation whatsoever to x86's RM boot code, but occur because realmode.h happens to include asm/io.h. - Patch 10 removes a spurious include of realmode.h from an ACPI header. - Patches 11 and 12 implement the wrapper and move it out of acpi.h. Sean Christopherson (12): x86/efi: Explicitly include realmode.h to handle RM trampoline quirk x86/boot: Explicitly include realmode.h to handle RM reservations x86/ftrace: Explicitly include vmalloc.h for set_vm_flush_reset_perms() x86/kprobes: Explicitly include vmalloc.h for set_vm_flush_reset_perms() perf/x86/intel: Explicitly include asm/io.h to use virt_to_phys() efi/capsule-loader: Explicitly include linux/io.h for page_to_phys() virt: vbox: Explicitly include linux/io.h to pick up various defs vmw_balloon: Explicitly include linux/io.h for virt_to_phys() ASoC: Intel: Skylake: Explicitly include linux/io.h for virt_to_phys() x86/ACPI/sleep: Remove an unnecessary include of asm/realmode.h ACPI/sleep: Convert acpi_wakeup_address into a function x86/ACPI/sleep: Move acpi_wakeup_address() definition into sleep.c arch/ia64/include/asm/acpi.h | 5 ++++- arch/ia64/kernel/acpi.c | 2 -- arch/x86/events/intel/ds.c | 1 + arch/x86/include/asm/acpi.h | 3 +-- arch/x86/kernel/acpi/sleep.c | 11 +++++++++++ arch/x86/kernel/acpi/sleep.h | 2 +- arch/x86/kernel/ftrace.c | 1 + arch/x86/kernel/kprobes/core.c | 1 + arch/x86/kernel/setup.c | 1 + arch/x86/platform/efi/quirks.c | 1 + drivers/acpi/sleep.c | 4 ++-- drivers/firmware/efi/capsule-loader.c | 1 + drivers/misc/vmw_balloon.c | 1 + drivers/virt/vboxguest/vboxguest_core.c | 1 + drivers/virt/vboxguest/vboxguest_utils.c | 1 + sound/soc/intel/skylake/skl-sst-cldma.c | 1 + 16 files changed, 29 insertions(+), 8 deletions(-) -- 2.24.0

[alsa-devel] [PATCH alsa-lib 1/4] ucm: Fix opening of master-configs by the card's longname
by Hans de Goede 25 Nov '19

25 Nov '19

Prior to commit aba2260ae7b5 ("ucm: switch to ucm2 directory and v2 format, keep backward compatibility"). The filename build in parse_verb_file() was build like this: <prefix>/<uc_mgr->conf_file_name>/<file> Where uc_mgr->conf_file_name would contain either the card_name or the card's longname depending on the detection of a longname based config in uc_mgr_import_master_config(). While the filename used in load_master_config() was build like this: <prefix>/<card_name>/<card_name>.conf And uc_mgr_import_master_config() first calls load_master_config() with the card's longname and if that succeeds it overwrites uc_mgr->conf_file_name with the longname so that the subsequent uses of uc_mgr->conf_file_name in parse_verb_file() correctly use the longname. But the new configuration_filename() helper added in commit aba2260ae7b5 _always_ builds the filename like this: <prefix>/<uc_mgr->conf_file_name>/<file><suffix> This breaks the loading of the master-config by its longname, as when the longname is tried uc_mgr->conf_file_name still contains the card_name. This commit fixes this by adding a dir parameter to configuration_filename() and restoring the old behavior by passing card_name as dir in load_master_config().

[alsa-devel] [PATCH 1/2] ALSA: aloop: Remove redundant locking in timer open function
by Andrew Gabbasov 22 Nov '19

22 Nov '19

loopback_parse_timer_id() uses snd_card_ref(), that can lock on mutex, also snd_timer_instance_new() uses non-atomic allocation, that can sleep. So, both functions can not be called from loopback_snd_timer_open() with cable->lock spinlock locked. Moreover, most part of loopback_snd_timer_open() function body works when the opposite stream of the same cable does not yet exist, and the current stream is not yet completely open and can't be running, so existing locking of loopback->cable_lock mutex is enough to protect from conflicts with simultaneous opening or closing.

Thanks. Thank you very much! Unfortunately, I found some issue with locking in patch 6 (sorry for late finding): loopback_parse_timer_id() uses snd_card_ref(), that can lock on mutex, also snd_timer_instance_new() uses non-atomic allocation, that can sleep. So, both functions can not be called from loopback_snd_timer_open() with cable->lock spinlock locked. Also, most part of loopback_snd_timer_open() function body works when the opposite stream of the same cable does not yet exist, and the current stream is not yet completely open and can't be running, so existing locking of loopback->cable_lock mutex is enough to protect from conflicts with simultaneous opening or closing. So, it looks like locking of cable->lock spinlock is not needed in loopback_snd_timer_open() at all (similarly to loopback_snd_timer_close_cable()). I'm sending a separate patch to fix this: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-November/159087.h tml Also, when you requested to move tasklet_init() call to before snd_timer_open() call, I should have guessed to look into the reverse closing side too ;-) Now, I have to add one more patch to move tasklet_kill() call to after snd_timer_close(). https://mailman.alsa-project.org/pipermail/alsa-devel/2019-November/159088.h tml Please, take a look at the patches. Thanks! Best regards, Andrew

[alsa-devel] [PATCH][RFC] ASoC: stm32: sai: manage rebind issue
by Olivier Moysan 22 Nov '19

22 Nov '19

The commit e894efef9ac7 ("ASoC: core: add support to card rebind") allows to rebind the sound card after a rebind of one of its component. With this commit, the sound card is actually rebound, but is no more functional. With the sound card rebind the simplified call sequence is: stm32_sai_sub_probe snd_soc_register_component snd_soc_try_rebind_card snd_soc_instantiate_card devm_snd_dmaengine_pcm_register The problem occurs because the pcm must be registered, before snd_soc_instantiate_card() is called. Modify SAI driver, to change the call sequence as follows: stm32_sai_sub_probe devm_snd_dmaengine_pcm_register snd_soc_register_component snd_soc_try_rebind_card --- The current patch allows to fix the issue for STM SAI driver. However, most of the drivers register the component first. So, this solution is perhaps not the right way to manage the problem. This may probably be handled in ASoC framework instead. --- Signed-off-by: Olivier Moysan <olivier.moysan(a)st.com> --- sound/soc/stm/stm32_sai_sub.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/sound/soc/stm/stm32_sai_sub.c b/sound/soc/stm/stm32_sai_sub.c index 48e629ac2d88..eb35306a1232 100644 --- a/sound/soc/stm/stm32_sai_sub.c +++ b/sound/soc/stm/stm32_sai_sub.c @@ -1484,6 +1484,13 @@ static int stm32_sai_sub_probe(struct platform_device *pdev) return ret; } + ret = devm_snd_dmaengine_pcm_register(&pdev->dev, conf, 0); + if (ret) { + dev_err(&pdev->dev, "Could not register pcm dma\n"); + return ret; + } + + ret = devm_snd_soc_register_component(&pdev->dev, &stm32_component, &sai->cpu_dai_drv, 1); if (ret) @@ -1492,11 +1499,6 @@ static int stm32_sai_sub_probe(struct platform_device *pdev) if (STM_SAI_PROTOCOL_IS_SPDIF(sai)) conf = &stm32_sai_pcm_config_spdif; - ret = devm_snd_dmaengine_pcm_register(&pdev->dev, conf, 0); - if (ret) { - dev_err(&pdev->dev, "Could not register pcm dma\n"); - return ret; - } return 0; } -- 2.17.1

[alsa-devel] [PATCH 0/2] ASoC: Follow the recent ALSA core API changes
by Takashi Iwai 22 Nov '19

22 Nov '19

Hi, this is a follow-up patch set for ASoC to adapt the recent ALSA PCM core changes. It's merely a preliminary and this itself doesn't change the current driver behavior. The purpose of this submission is to get the basic API changes done in 5.5-rc1, so that other trees can apply the actual changes later individually. The actual cleanups and changes in the driver side will be submitted after 5.5 merge window. Mark, if you are OK with this, please give ACK. Then I'll merge them into my tree for 5.5-rc1. thanks, Takashi === Takashi Iwai (2): ASoC: pcm: Make ioctl ops optional ASoC: component: Add sync_stop PCM ops include/sound/soc-component.h | 3 +++ sound/soc/soc-component.c | 19 +++++++++++++++++++ sound/soc/soc-pcm.c | 6 ++++-- 3 files changed, 26 insertions(+), 2 deletions(-) -- 2.16.4

[alsa-devel] [PATCH] ALSA: cs4236: fix error return comparison of an unsigned integer
by Colin King 22 Nov '19

22 Nov '19

From: Colin Ian King <colin.king(a)canonical.com> The return from pnp_irq is an unsigned integer type resource_size_t and hence the error check for a positive non-error code is always going to be true. A check for a non-failure return from pnp_irq should in fact be for (resource_size_t)-1 rather than >= 0.

[alsa-devel] [PATCH] ALSA: hda/hdmi - Clear codec->relaxed_resume flag at unbinding
by Takashi Iwai 22 Nov '19

The HDMI codec may leave codec->relaxed_resume flag set even after unbinding. Clear it unconditionally. It's very unlikely that this actually matters in the real use case, so just a fix for consistency.

[alsa-devel] [PATCH] ALSA: hda - Disable audio component for legacy Nvidia HDMI codecs
by Takashi Iwai 22 Nov '19

22 Nov '19

The old Nvidia chips have multiple HD-audio codecs on the same HD-audio controller, and this doesn't work as expected with the current audio component binding that is implemented under the one-codec-per- controller assumption; at the probe time, the driver leads to several kernel WARNING messages. For the proper support, we may change the pin2port and port2pin to traverse the codec list per the given pin number, but this needs more development and testing. As a quick workaround, instead, this patch drops the binding in the audio side for these legacy chips since the audio component support in nouveau graphics driver is still not merged (hence it's basically unused).

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.

[alsa-devel] [PATCH 0/8] ALSA: pcm: API cleanups and extensions
by Takashi Iwai 22 Nov '19

22 Nov '19

Hi, this is a patch series for a few ALSA PCM API changes. Basically the patch set introduces three changes: * Add the "managed buffer allocation" mode; this allows many drivers to drop hw_params and hw_free callbacks that simply call snd_pcm_lib_malloc_pages() and *_free_pages(). * Make PCM ioctl ops optional; almost all driver can drop the lines to define pcm_ops.ioctl. * The new sync_stop PCM ops and card->sync_irq; it's used to synchronize the pending task after stopping the stream, for fixing the use-after-free or such problem. I planned originally merging these changes to 5.6. But since the API changes would influence on many drivers outside sound git tree, it might be easier to merge only these core changes at first during 5.5 merge window while keeping the rest (the actual driver implementations) intact -- that's why I post now for reviews. The changes are additional, and they won't break things by themselves. The drivers can / need to change the call patterns for following these new APIs. thanks, Takashi === Takashi Iwai (8): ALSA: pcm: Introduce managed buffer allocation mode ALSA: docs: Update for managed buffer allocation mode ALSA: pcm: Allow NULL ioctl ops ALSA: docs: Update document about the default PCM ioctl ops ALSA: pcm: Move PCM_RUNTIME_CHECK() macro into local header ALSA: pcm: Add the support for sync-stop operation ALSA: pcm: Add card sync_irq field ALSA: docs: Update about the new PCM sync_stop ops .../sound/kernel-api/writing-an-alsa-driver.rst | 148 +++++++++++++++------ include/sound/core.h | 1 + include/sound/pcm.h | 12 +- sound/core/init.c | 1 + sound/core/pcm_local.h | 2 + sound/core/pcm_memory.c | 83 ++++++++++-- sound/core/pcm_native.c | 48 ++++++- 7 files changed, 237 insertions(+), 58 deletions(-) -- 2.16.4

[alsa-devel] alsa-lib Plugin: File deadlock when piping to shell command
by GitHub issues - edited 21 Nov '19

21 Nov '19

[alsa-devel] [RESEND PATCH v11 6/6] ASoC: amd: Added ACP3x system resume and runtime pm
by Ravulapati Vishnu vardhan rao 21 Nov '19

21 Nov '19

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.

[alsa-devel] [PATCH] ASoC: rsnd: fix DALIGN register for SSIU

From: Nilkanth Ahirrao <anilkanth(a)jp.adit-jv.com> The current driver only sets 0x76543210 and 0x67452301 for DALIGN. This doesn’t work well for TDM split and ex-split mode for all SSIU.

[alsa-devel] ASoC, DMI and UCM
by Jaroslav Kysela 20 Nov '19

20 Nov '19

Hi all, I would like to discuss the way we use DMI information for the board identification in ASoC for the user space (long card name). It's a bit redundant information, because DMI is already exposed through /sys/class/dmi/id/ to the user space nowadays. My idea is to add 'DMI:sysfs' ctl info component string for the appropriate ASoC driver to detect the existence of this dmi interface. Then I can add the sysfs support to the ucm2 conditions. But it's really a quick idea. I'd like to have comments. Thank you, Jaroslav -- Jaroslav Kysela <perex(a)perex.cz> Linux Sound Maintainer; ALSA Project; Red Hat, Inc.

[alsa-devel] [PATCH v5 0/7] ALSA: aloop: Support sound timer as clock source instead of jiffies
by Andrew Gabbasov 20 Nov '19

20 Nov '19

This patch set is an updated version of patches by Timo Wischer: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-March/146871.html This patch set is required for forwarding audio data between a HW sound card and an aloop device without the usage of an asynchronous sample rate converter. Most of sound and timers related code is kept the same as in previous set. The code, related to snd_pcm_link() functionality and its using for timer source setting, is removed (as rejected earlier). The changes in this update are mainly related to the parameters handling and some cleanup. The timer source can be initially selected by "timer_source" kernel module parameter. It is supposed to have the following format: [<pref>:](<card name>|<card idx>)[{.,}<dev idx>[{.,}<subdev idx>]] For example: "hw:I82801AAICH.1.0", or "1.1", or just "I82801AAICH". (Prefix is ignored, just allowed here to be able to use the strings, the user got used to). Although the parsing function recognizes both '.' and ',' as a separator, module parameters handling routines use ',' to separate parameters for different module instances (array elements), so we have to use '.' to separate device and subdevice numbers from the card name or number in module parameters. Empty string indicates using jiffies as a timer source. Besides "static" selection of timer source at module load time, it is possible to dynamically change it via sound "info" interface (using "/proc/asound/<card>/timer_source" file in read-write mode. The contents of this file is used as a timer source string for a particular loopback card, e.g. "hw:0,0,0" (and here ',' can be used as a separator). The timer source string value can be changed at any time, but it is latched by PCM substream open callback "loopback_open()" (the first one for a particular cable). At this point it is actually used, that is the string is parsed, and the timer is looked up and opened. This seems to be a good trade-off between flexibility of updates and synchronizations or racing complexity. The timer source is set for a loopback card (the same as initial setting by module parameter), but every cable uses the value, current at the moment of opening. Theoretically, it's possible to set the timer source for each cable independently (via separate files), but it would be inconsistent with the initial setting via module parameters on a per-card basis. v2: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-November/157961.… v3: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-November/158312.… - Change sound card lookup to use snd_card_ref() and avoid direct access to sound cards array - Squash commits on returning error codes for timer start and stop - Some locking related fixes - Some code cleanup v4: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-November/158896.… - Change to use updated API for snd_timer_open() (separate timer instance) - Change to use snd_timer_close() returning void - Some code cleanup v5: - Change to initialize timer event tasklet before calling snd_timer_open() Andrew Gabbasov (1): ALSA: aloop: Support runtime change of snd_timer via info interface Timo Wischer (6): ALSA: aloop: Describe units of variables ALSA: aloop: Support return of error code for timer start and stop ALSA: aloop: Use callback functions for timer specific implementations ALSA: aloop: Rename all jiffies timer specific functions ALSA: aloop: Move CABLE_VALID_BOTH to the top of file ALSA: aloop: Support selection of snd_timer instead of jiffies sound/drivers/aloop.c | 663 +++++++++++++++++++++++++++++++++++++++--- 1 file changed, 628 insertions(+), 35 deletions(-) -- 2.21.0

[alsa-devel] [PATCH] Revert "ASoC: soc-pcm: check symmetry after hw_params"

That commit cause soc_pcm_params_symmetry can't take effect. cpu_dai->rate, cpu_dai->channels and cpu_dai->sample_bits are updated in the middle of soc_pcm_hw_params, so move soc_pcm_params_symmetry to the end of soc_pcm_hw_params is not a good solution, for judgement of symmetry in the function is always true.

So a new symbol `UPMIX_PCM_FORMAT` is added to hide the actual format, and a special type `upmix_sample_t` marks the sample type, instead of fixed `short`. I fixed the `average_copy` function as well, which was actually expecting the `nchns` parameter to be 2, otherwise its local arrays would be overindexed. The rest is just better naming for `i` as it denotes the channel index in every case, and applying consistent whitespace. The behavior of the plugin remains identical though.

I'll move this initialization to before snd_timer_open() in the next update together with the fixes for the other issues you will find in this version. Thanks! Best regards, Andrew

[alsa-devel] [PATCH v3 0/7] ALSA: aloop: Support sound timer as clock source instead of jiffies
by Andrew Gabbasov 20 Nov '19

20 Nov '19

This patch set is an updated version of patches by Timo Wischer: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-March/146871.html This patch set is required for forwarding audio data between a HW sound card and an aloop device without the usage of an asynchronous sample rate converter. Most of sound and timers related code is kept the same as in previous set. The code, related to snd_pcm_link() functionality and its using for timer source setting, is removed (as rejected earlier). The changes in this update are mainly related to the parameters handling and some cleanup. The timer source can be initially selected by "timer_source" kernel module parameter. It is supposed to have the following format: [<pref>:](<card name>|<card idx>)[{.,}<dev idx>[{.,}<subdev idx>]] For example: "hw:I82801AAICH.1.0", or "1.1", or just "I82801AAICH". (Prefix is ignored, just allowed here to be able to use the strings, the user got used to). Although the parsing function recognizes both '.' and ',' as a separator, module parameters handling routines use ',' to separate parameters for different module instances (array elements), so we have to use '.' to separate device and subdevice numbers from the card name or number in module parameters. Empty string indicates using jiffies as a timer source. Besides "static" selection of timer source at module load time, it is possible to dynamically change it via sound "info" interface (using "/proc/asound/<card>/timer_source" file in read-write mode. The contents of this file is used as a timer source string for a particular loopback card, e.g. "hw:0,0,0" (and here ',' can be used as a separator). The timer source string value can be changed at any time, but it is latched by PCM substream open callback "loopback_open()" (the first one for a particular cable). At this point it is actually used, that is the string is parsed, and the timer is looked up and opened. This seems to be a good trade-off between flexibility of updates and synchronizations or racing complexity. The timer source is set for a loopback card (the same as initial setting by module parameter), but every cable uses the value, current at the moment of opening. Theoretically, it's possible to set the timer source for each cable independently (via separate files), but it would be inconsistent with the initial setting via module parameters on a per-card basis. v2: https://mailman.alsa-project.org/pipermail/alsa-devel/2019-November/157961.… v3: - Change sound card lookup to use snd_card_ref() and avoid direct access to sound cards array - Squash commits on returning error codes for timer start and stop - Some locking related fixes - Some code cleanup Andrew Gabbasov (1): ALSA: aloop: Support runtime change of snd_timer via info interface Timo Wischer (6): ALSA: aloop: Describe units of variables ALSA: aloop: Support return of error code for timer start and stop ALSA: aloop: Use callback functions for timer specific implementations ALSA: aloop: Rename all jiffies timer specific functions ALSA: aloop: Move CABLE_VALID_BOTH to the top of file ALSA: aloop: Support selection of snd_timer instead of jiffies sound/drivers/aloop.c | 672 +++++++++++++++++++++++++++++++++++++++--- 1 file changed, 637 insertions(+), 35 deletions(-) -- 2.21.0

[alsa-devel] Focusrite Scarlett 6i6 gen1 - input handling fix
by Jens Verwiebe 19 Nov '19

19 Nov '19

The Scarlett 6i6 has no padding on rear inputs 3/4 but a gainstage. This patch introduces this functionality as to be seen in the mac or windows scarlett control. The correct address could already be found in the dump info, but was never used. Cheers ...

[alsa-devel] [RESEND PATCH v9 6/6] ASoC: amd: Added ACP3x system resume and runtime pm
by Ravulapati Vishnu vardhan rao 19 Nov '19

19 Nov '19

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.
