[PATCHv2 00/10] ASoC: fsl-asoc-card: compatibility integration of a generic codec use case for use with S/PDIF controller
by Elinor Montmasson 20 Nov '23

20 Nov '23

Hello, This is the v2 of the series of patch aiming to make the machine driver fsl-asoc-card compatible with use cases where there is no real codec driver. It proposes to use the spdif_receiver and spdif_transmitter drivers instead of the dummy codec. This is a first step in using the S/PDIF controller with the ASRC. The five first patches add compatibility with the pair of codecs spdif_receiver and spdif_transmitter with a new compatible, "fsl,imx-audio-generic". Codec parameters are set with default values. The remaining patches add configuration options for the device tree. They configure the CPU DAI when using "fsl,imx-audio-generic". These are usually hard-coded in fsl-asoc-card for each audio codec. Because the generic codec could be used with other CPU DAI than the S/PDIF controller, setting these parameters could be required. This series of patch was successfully built for arm64 and x86 on top of the latest for-next branch of the ASoC git tree on the 24/10. These modifications have also been tested on an i.MX8MN evaluation board, with a linux kernel RT v6.1.26-rt8. We also have a few questions : * We named the compatible "fsl,imx-audio-generic" as, for the moment, it could work with any CPU DAI, even if it uses S/PDIF codecs. Is it preferable to keep these modifications specific to the S/PDIF, thus specifying "spdif" in the compatible ? Or is it okay to keep the actual name of the compatible, and the generic purpose of this compatible ? * Part of the dai_fmt variable hold information on the codec provider or consumer status for bit/frame clocks. In patch 03/10, as we add compatibility for multiple codecs, we make the test about bit/frame clock provider only check with codec[0]. That way we assure compatibility with all already existing compatibles. As it was never intended before to have multiple codecs for this test, is there a better way to handle it ? Should we make this test check if any codec is clock provider ? Or should we let codec[0] be the default possibility ? That way, future compatibles that could encounter this specific case with multi-codecs should adapt the test for their needs. Best regards, Elinor Montmasson Changelog: v1 -> v2: * replace use of the dummy codec by the pair of codecs spdif_receiver / spdif_transmitter * adapt how dai links codecs are used to take into account the possibility for multiple codecs per link * change compatible name * adapt driver to be able to register two codecs given in the device tree * v1 patch series at: https://lore.kernel.org/alsa-devel/20230901144550.520072-1-elinor.montmasso… Elinor Montmasson (10): ASoC: fsl-asoc-card: add support for dai links with multiple codecs ASoC: fsl-asoc-card: add second dai link component for codecs ASoC: fsl-asoc-card: add compatibility to use 2 codecs from device tree ASoC: fsl-asoc-card: add new compatible for a generic codec use case ASoC: fsl-asoc-card: set generic codec as clock provider ASoC: fsl-asoc-card: add dts property "cpu-slot-width" ASoC: fsl-asoc-card: add dts property "cpu-slot-num" ASoC: fsl-asoc-card: add dts properties "cpu-sysclk-freq" ASoC: fsl-asoc-card: add dts properties "cpu-sysclk-dir-out" Documentation: fsl-asoc-card: add documentation for generic codec case .../bindings/sound/fsl-asoc-card.txt | 26 +++- sound/soc/fsl/fsl-asoc-card.c | 128 ++++++++++++------ 2 files changed, 114 insertions(+), 40 deletions(-) -- 2.25.1

[PATCH v2 00/17] ALSA/ASoC: hda: Address format selection limitations and ambiguity
by Cezary Rojewski 14 Nov '23

14 Nov '23

Patchset aims to address format selection restrictions present currently in the HDAudio library. Formats which we are concerned about are 20 and 24 valid bits per sample within 32 bit depth container. One may identify them as S20_LE and S24_LE except that those, according to comments found in include/uapi/sound/asound.h, are for LSB-aligned scenarios. HDAudio streams expect MSB-aligned data, no matter if we are speaking of HOST (SDxFMT) or LINK (PPLCxFMT) side - chapter 4.5.1 of the public HDAudio specification. In short, S20_LE and S24_LE are invalid options. Right now, given the implementation of snd_hdac_query_supported_pcm() within sound/hda/hdac_device.c, even if a codec responds with: "I support all possible formats specified within HDAudio specification", there will be no option to open a 20/32 or 24/32 stream. The kernel will force the stream to be opened using the highest available bit depth. After discussing subject initially with Jaroslav and Takashi, suggestion was made to utilize 'subformat' option to address the problem. The eye-opening discussion begun much earlier though, in 2019 [1]. Paired with PRs for alsa-utils [2] and alsa-lib [3]. Flow of changes: The very first patch adds MSBITS subformat options to allow for granular 20/32, 24/32 and 32/32 format selection. The next three make sure subformat is actually honored during runtime. Most of that code is based on format-related API. Follow up is upgrade to the hda stream-format interface - several functions are added to make the granular format selection simple in the HDAudio world. Core of the implementation is based on the existing snd_hdac_calc_stream_format(). The next ten patches are straightforward switch from one interface to another with cleanup of now-unsed function as a finishing touch. Last but not least - the avs-driver, on which the problem analyzed and debugged, is updated to no longer acknowledge S24_LE as a valid format option. Results with skylake-driver and snd_hda_intel show status quo on our RVPs. PR filed on SOF github shows promising results too [4]. Changes in v2: - patch 01/17, introduced struct snd_pcm_subformat which task is to represent subformat-mask on per format basis. Expectation is that manipulated arrays of subformats always end with a sentinel entry - patch 01/17, added snd_pcm_hw_copy() as the copying snd_pcm_hardware becomes non-trivial - patch 02/17, added hw_rule that produces final subformat mask based on provided formats as suggested by Jaroslav - patch 04/17, soc_pcm_hw_update_subformat() refactored as the subformat intersection becomes non-trivial - relevant functions releasing resources occupied by hda_pcm and snd_pcm_runtime updated to also kfree() subformats - except for 16/17, no changes to patches past 04/17, retaining acks for these Changes in v1: - fixed UBSAN due to missing snd_pcm_subformat_names[] entries for new subformats - as HDMI stream capabilities are assigned on PCM open, patch 16/17 has been updated to ignore such codecs for now. A separate patchset will take care of this case - params_bps() reworded to snd_pcm_hw_params_bps() - fixed compilation issues in sof-driver, patch 13/17 [1]: https://lore.kernel.org/alsa-devel/20190905053302.9262-1-pawel.harlozinski@… [2]: https://github.com/alsa-project/alsa-utils/pull/228 [3]: https://github.com/alsa-project/alsa-lib/pull/342 [4]: https://github.com/thesofproject/linux/pull/4539 Cezary Rojewski (17): ALSA: pcm: Introduce MSBITS subformat interface ALSA: pcm: Honor subformat when configuring substream ALSA: hda: Honor subformat when querying PCMs ASoC: pcm: Honor subformat when configuring runtime ALSA: hda: Upgrade stream-format infrastructure ALSA: hda: Switch to new stream-format interface ALSA: hda/hdmi: Switch to new stream-format interface ALSA: hda/ca0132: Switch to new stream-format interface ASoC: codecs: hda: Switch to new stream-format interface ASoC: codecs: hdac_hda: Switch to new stream-format interface ASoC: codecs: hdac_hdmi: Switch to new stream-format interface ASoC: Intel Skylake: Switch to new stream-format interface ASoC: SOF: Intel: Switch to new stream-format interface ASoC: Intel: avs: Switch to new stream-format interface ALSA: hda: Drop snd_hdac_calc_stream_format() ASoC: Intel: avs: Kill S24_LE in HDAudio streaming ASoC: Intel: avs: Unhardcode HDAudio BE DAI drivers description include/sound/hda_codec.h | 5 +- include/sound/hdaudio.h | 14 +-- include/sound/pcm.h | 14 +++ include/sound/pcm_params.h | 2 + include/sound/soc.h | 1 + include/uapi/sound/asound.h | 7 +- sound/core/pcm.c | 4 + sound/core/pcm_lib.c | 28 +++++ sound/core/pcm_misc.c | 51 ++++++++++ sound/core/pcm_native.c | 67 +++++++++++- sound/hda/hdac_device.c | 163 ++++++++++++++++++++++-------- sound/pci/hda/hda_codec.c | 5 + sound/pci/hda/hda_controller.c | 10 +- sound/pci/hda/patch_ca0132.c | 3 +- sound/pci/hda/patch_hdmi.c | 6 +- sound/soc/codecs/hda-dai.c | 6 +- sound/soc/codecs/hda.c | 2 + sound/soc/codecs/hdac_hda.c | 8 +- sound/soc/codecs/hdac_hdmi.c | 10 +- sound/soc/intel/avs/loader.c | 4 +- sound/soc/intel/avs/path.c | 2 +- sound/soc/intel/avs/pcm.c | 54 ++++++++-- sound/soc/intel/avs/probes.c | 3 +- sound/soc/intel/avs/topology.c | 19 +++- sound/soc/intel/skylake/skl-pcm.c | 11 +- sound/soc/soc-pcm.c | 35 ++++++- sound/soc/sof/intel/hda-dai-ops.c | 5 +- tools/include/uapi/sound/asound.h | 7 +- 28 files changed, 443 insertions(+), 103 deletions(-) base-commit: 564ee9ac788b680e4ec4a6cb3a4a953dc61d5da8 -- 2.25.1

[PATCH v3 00/42] ep93xx device tree conversion
by Nikita Shubin via B4 Relay 13 Nov '23

13 Nov '23

This series aims to convert ep93xx from platform to full device tree support. The main goal is to receive ACK's to take it via Arnd's arm-soc branch. I've moved to b4, tricking it to consider v0 as v1, so it consider's this version to be v3, this exactly the third version. Link to previous versions: https://lore.kernel.org/all/20230424123522.18302-1-nikita.shubin@maquefel.m… Major changes with clocks: - split all ep93xx clk into two groups: - those who are special to ep93xx (i.e. can't be implemented via standard clk's) and use special swlocked registers - those who can be implemented via devm_clk_hw_register_gate, etc... - moved all clk's that are not used via device tree to SoC driver - dropped init and globals - devm_* everywhere Other notable changes: - added a global spinlock for SoC driver to protect swlocked register's. - moved dts file into cirrus - dropped "dt-bindings: gpio: Add Cirrus EP93xx" as it was taken by Bartosz via gpio subsystem on master v6.5-rc2-89-g3acbd4602b05: make dtbs_check ``` make -j34 -C build-linux ARCH=arm CROSS_COMPILE=armv4t-softfloat-linux-gnueabi- dtbs_check -s arch/arm/boot/dts/cirrus/ep93xx-edb9302.dtb:0:0: /soc/spi@808a0000/codec@0: failed to match any schema with compatible: ['cirrus,cs4271'] /home/maquefel/workshop/ts7250-boot-build/build-linux/arch/arm/boot/dts/cirrus/ep93xx-edb9302.dtb: sound: 'simple-audio-card,convert-sample-format' does not match any of the regexes: '^simple-audio-card,codec(@[0-9a-f]+)?$', '^simple-audio-card,cpu(@[0-9a-f]+)?$', '^simple-audio-card,dai-link(@[0-9a-f]+)?$', '^simple-audio-card,plat(@[0-9a-f]+)?$', 'pinctrl-[0-9]+' From schema: /home/maquefel/workshop/ts7250-boot-build/linux/Documentation/devicetree/bindings/sound/simple-card.yaml ``` cirrus,cs4271 is defined in linux/Documentation/devicetree/bindings/sound/cs4271.txt `make dt_binding_check` shows no issues.

[RFC PATCH v8 00/13] Add audio support in v4l2 framework
by Shengjiu Wang 07 Nov '23

07 Nov '23

Audio signal processing also has the requirement for memory to memory similar as Video. This asrc memory to memory (memory ->asrc->memory) case is a non real time use case. User fills the input buffer to the asrc module, after conversion, then asrc sends back the output buffer to user. So it is not a traditional ALSA playback and capture case. It is a specific use case, there is no reference in current kernel. v4l2 memory to memory is the closed implementation, v4l2 current support video, image, radio, tuner, touch devices, so it is not complicated to add support for this specific audio case. Because we had implemented the "memory -> asrc ->i2s device-> codec" use case in ALSA. Now the "memory->asrc->memory" needs to reuse the code in asrc driver, so the first 3 patches is for refining the code to make it can be shared by the "memory->asrc->memory" driver. The main change is in the v4l2 side, A /dev/vl4-audioX will be created, user applications only use the ioctl of v4l2 framework. Other change is to add memory to memory support for two kinds of i.MX ASRC module. changes in v8: - refine V4L2_CAP_AUDIO_M2M to be 0x00000008 - update doc for FIXED_POINT - address comments for imx-asrc changes in v7: - add acked-by from Mark - separate commit for fixed point, m2m audio class, audio rate controls - use INTEGER_MENU for rate, FIXED_POINT for rate offset - remove used fmts - address other comments for Hans changes in v6: - use m2m_prepare/m2m_unprepare/m2m_start/m2m_stop to replace m2m_start_part_one/m2m_stop_part_one, m2m_start_part_two/m2m_stop_part_two. - change V4L2_CTRL_TYPE_ASRC_RATE to V4L2_CTRL_TYPE_FIXED_POINT - fix warning by kernel test rebot - remove some unused format V4L2_AUDIO_FMT_XX - Get SNDRV_PCM_FORMAT from V4L2_AUDIO_FMT in driver. - rename audm2m to viaudm2m. changes in v5: - remove V4L2_AUDIO_FMT_LPCM - define audio pixel format like V4L2_AUDIO_FMT_S8... - remove rate and format in struct v4l2_audio_format. - Add V4L2_CID_ASRC_SOURCE_RATE and V4L2_CID_ASRC_DEST_RATE controls - updata document accordingly. changes in v4: - update document style - separate V4L2_AUDIO_FMT_LPCM and V4L2_CAP_AUDIO_M2M in separate commit changes in v3: - Modify documents for adding audio m2m support - Add audio virtual m2m driver - Defined V4L2_AUDIO_FMT_LPCM format type for audio. - Defined V4L2_CAP_AUDIO_M2M capability type for audio m2m case. - with modification in v4l-utils, pass v4l2-compliance test. changes in v2: - decouple the implementation in v4l2 and ALSA - implement the memory to memory driver as a platfrom driver and move it to driver/media - move fsl_asrc_common.h to include/sound folder Shengjiu Wang (13): ASoC: fsl_asrc: define functions for memory to memory usage ASoC: fsl_easrc: define functions for memory to memory usage ASoC: fsl_asrc: move fsl_asrc_common.h to include/sound ASoC: fsl_asrc: register m2m platform device ASoC: fsl_easrc: register m2m platform device media: uapi: Add V4L2_CAP_AUDIO_M2M capability flag media: v4l2: Add audio capture and output support media: uapi: Define audio sample format fourcc type media: uapi: Add V4L2_CTRL_CLASS_M2M_AUDIO media: uapi: Add V4L2_CTRL_TYPE_FIXED_POINT media: uapi: Add audio rate controls support media: imx-asrc: Add memory to memory driver media: vim2m_audio: add virtual driver for audio memory to memory .../userspace-api/media/v4l/buffer.rst | 6 + .../userspace-api/media/v4l/common.rst | 1 + .../media/v4l/dev-audio-mem2mem.rst | 71 + .../userspace-api/media/v4l/devices.rst | 1 + .../media/v4l/ext-ctrls-audio-m2m.rst | 41 + .../userspace-api/media/v4l/pixfmt-audio.rst | 87 ++ .../userspace-api/media/v4l/pixfmt.rst | 1 + .../media/v4l/vidioc-enum-fmt.rst | 2 + .../media/v4l/vidioc-g-ext-ctrls.rst | 17 +- .../userspace-api/media/v4l/vidioc-g-fmt.rst | 4 + .../media/v4l/vidioc-querycap.rst | 3 + .../media/v4l/vidioc-queryctrl.rst | 9 +- .../media/videodev2.h.rst.exceptions | 4 + .../media/common/videobuf2/videobuf2-v4l2.c | 4 + drivers/media/platform/nxp/Kconfig | 12 + drivers/media/platform/nxp/Makefile | 1 + drivers/media/platform/nxp/imx-asrc.c | 1186 +++++++++++++++++ drivers/media/test-drivers/Kconfig | 9 + drivers/media/test-drivers/Makefile | 1 + drivers/media/test-drivers/vim2m_audio.c | 680 ++++++++++ drivers/media/v4l2-core/v4l2-ctrls-api.c | 5 +- drivers/media/v4l2-core/v4l2-ctrls-core.c | 2 + drivers/media/v4l2-core/v4l2-ctrls-defs.c | 16 + drivers/media/v4l2-core/v4l2-dev.c | 17 + drivers/media/v4l2-core/v4l2-ioctl.c | 66 + include/media/v4l2-dev.h | 2 + include/media/v4l2-ioctl.h | 34 + .../fsl => include/sound}/fsl_asrc_common.h | 60 + include/uapi/linux/v4l2-controls.h | 9 + include/uapi/linux/videodev2.h | 42 + sound/soc/fsl/fsl_asrc.c | 144 ++ sound/soc/fsl/fsl_asrc.h | 4 +- sound/soc/fsl/fsl_asrc_dma.c | 2 +- sound/soc/fsl/fsl_easrc.c | 233 ++++ sound/soc/fsl/fsl_easrc.h | 6 +- 35 files changed, 2771 insertions(+), 11 deletions(-) create mode 100644 Documentation/userspace-api/media/v4l/dev-audio-mem2mem.rst create mode 100644 Documentation/userspace-api/media/v4l/ext-ctrls-audio-m2m.rst create mode 100644 Documentation/userspace-api/media/v4l/pixfmt-audio.rst create mode 100644 drivers/media/platform/nxp/imx-asrc.c create mode 100644 drivers/media/test-drivers/vim2m_audio.c rename {sound/soc/fsl => include/sound}/fsl_asrc_common.h (60%) -- 2.34.1

[PATCH 1/3] soundwire: qcom: drop unneeded DAI .set_stream callback
by Krzysztof Kozlowski 06 Nov '23

06 Nov '23

Qualcomm Soundwire controller drivers do not support multi-link setups, so DAI .set_stream() callback will not be used. What's more, if called it will overwrite the sdw_stream_runtime runtime set in DAI .startup (qcom_swrm_startup()) causing issues (unsupported multi-link error) when two Soundwire controllers are passed as codec DAIs.
