[PATCH v3 0/5] ASoC: qcom: volume fixes and codec cleanups
by Johan Hovold 19 Jan '24

19 Jan '24

To reduce the risk of speaker damage the PA gain needs to be limited on machines like the Lenovo Thinkpad X13s until we have active speaker protection in place. Limit the gain to the current default setting provided by the UCM configuration which most user have so far been using (due to a bug in the configuration files which prevented hardware volume control [1]). The wsa883x PA volume control also turned out to be broken, which meant that the default setting used by UCM configuration is actually the lowest level (-3 dB). With the codec driver fixed, hardware volume control also works as expected once we lift the PA volume limit. Note that the new wsa884x driver most likely suffers from a similar bug, I'll send a fix for that once I've got that confirmed. Included is also a related fix for the LPASS WSA macro driver, which was changing the digital gain setting behind the back of user space and which can result in excessive (or too low) digital gain. There are further Qualcomm codec drivers that similarly appear to manipulate various gain settings, but on closer inspection it turns out that they only write back the current settings. Tests reveal that these writes are indeed needed for any prior updates to take effect (at least for the WSA and RX macros). Johan [1] https://github.com/alsa-project/alsa-ucm-conf/pull/382 Changes in v3 - fix the wsa883x PA volume control and update the machine limits accordingly Changes in v2 - keep the volume register write on power-on in lpass-wsa-macro - drop the other patches removing volume register writes on DAPM events - only drop the constant-zero gain offsets in wcd9335 Johan Hovold (5): ASoC: codecs: wsa883x: fix PA volume control ASoC: codecs: wsa883x: lower default PA gain ASoC: qcom: sc8280xp: limit speaker volumes ASoC: codecs: lpass-wsa-macro: fix compander volume hack ASoC: codecs: wcd9335: drop unused gain hack remnant sound/soc/codecs/lpass-wsa-macro.c | 7 ------- sound/soc/codecs/wcd9335.c | 4 ---- sound/soc/codecs/wsa883x.c | 6 +++--- sound/soc/qcom/sc8280xp.c | 8 +++++--- 4 files changed, 8 insertions(+), 17 deletions(-) -- 2.41.0

Clarify snd_pcm_hw_params_set_drain_silence documentation
by GitHub issues - opened 18 Jan '24

18 Jan '24

alsa-project/alsa-lib issue #378 was opened from z-s-e: The API documentation states that drain silence is enabled by default. But since this is a hardware parameter, is it possible that some hardware does not support this? Or is this always available (and will cause alsa-lib internal software workarounds for hardware that doesn't have perfect drain)? Also, the documentation mentions the sw_params silencing mechanism as usable for a manual emulation of this, but the documentation of the sw_params silence_size/silence_threshold imply they only affect the silencing behavior in case of underrun, not in case of draining. I can create a patch for the documentation if you'd like, as soon as I get the needed info.

[PATCH v11 00/15] Add audio support in v4l2 framework
by Shengjiu Wang 18 Jan '24

18 Jan '24

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 v11 - add add-fixed-point-test-controls in vivid. - add v4l2_ctrl_fp_compose() helper function for min and max changes in v10 - remove FIXED_POINT type - change code base on media: v4l2-ctrls: add support for fraction_bits - fix issue reported by kernel test robot - remove module_alias changes in v9: - add MEDIA_ENT_F_PROC_AUDIO_RESAMPLER. - add MEDIA_INTF_T_V4L_AUDIO - add media controller support - refine the vim2m-audio to support 8k<->16k conversion. 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 (15): 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 audio rate controls support media: uapi: Declare interface types for Audio media: uapi: Add an entity type for audio resampler media: vivid: add fixed point test controls media: imx-asrc: Add memory to memory driver media: vim2m-audio: add virtual driver for audio memory to memory .../media/mediactl/media-types.rst | 11 + .../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 | 4 + .../userspace-api/media/v4l/vidioc-g-fmt.rst | 4 + .../media/v4l/vidioc-querycap.rst | 3 + .../media/videodev2.h.rst.exceptions | 3 + .../media/common/videobuf2/videobuf2-v4l2.c | 4 + drivers/media/platform/nxp/Kconfig | 13 + drivers/media/platform/nxp/Makefile | 1 + drivers/media/platform/nxp/imx-asrc.c | 1264 +++++++++++++++++ drivers/media/test-drivers/Kconfig | 11 + drivers/media/test-drivers/Makefile | 1 + drivers/media/test-drivers/vim2m-audio.c | 799 +++++++++++ drivers/media/test-drivers/vivid/vivid-core.h | 2 + .../media/test-drivers/vivid/vivid-ctrls.c | 26 + drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 9 + drivers/media/v4l2-core/v4l2-ctrls-defs.c | 10 + drivers/media/v4l2-core/v4l2-dev.c | 21 + drivers/media/v4l2-core/v4l2-ioctl.c | 66 + drivers/media/v4l2-core/v4l2-mem2mem.c | 13 +- include/media/v4l2-ctrls.h | 3 + include/media/v4l2-dev.h | 2 + include/media/v4l2-ioctl.h | 34 + .../fsl => include/sound}/fsl_asrc_common.h | 60 + include/uapi/linux/media.h | 2 + include/uapi/linux/v4l2-controls.h | 9 + include/uapi/linux/videodev2.h | 41 + 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 +- 39 files changed, 3008 insertions(+), 7 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 v3 0/5] reset: gpio: ASoC: shared GPIO resets
by Krzysztof Kozlowski 17 Jan '24

17 Jan '24

Hi, Changes in v3 ============= 1. reset-gpio.c: - Add reset_gpio_of_xlate (Philipp). - reset_gpio_of_args_put->reset_gpio_of_node_put (Philipp). - Expect via platdata of_phandle_args. - Do not call device_set_node() to attach itself to reset consumer (the final device). This was questionable idea in the first place. Bartosz suggested to use GPIO_LOOKUP to solve this. 2. reset/core.c, implement Philipp's feedback. That was a lot: - Commit msg fixes. - Add new platform_device earlier, when reset core found "reset-gpios" but not "resets". - Do not overwrite of_phandle_args. - Expect matching .of_reset_n_cells. - Pass of_phandle_args as platdata to reset-gpio. - Rename reset_gpio_device->reset_gpio_lookup and others. Fix few comments and code cleanup pointed on review. - From Bartosz: Use GPIO_LOOKUP and a lot of cleanup.h in __reset_add_reset_gpio_lookup(). 3. Include here Chris' patch: "i2c: muxes: pca954x: Allow sharing reset GPIO". Changes in v2 ============= 1. wsa884x.c: add missing return in wsa884x_get_reset(), correct comment. 2. qcom,wsa8840.yaml: fix oneOf syntax. 3. reset-gpio.c: - Fix smatch warning on platdata evaluation. - Parse GPIO args and store them in rc.of_args. 4. reset/core.c: - Revise approach based on Bartosz comments: parse the reset-gpios phandle with arguments, do not use deprecated API and do not rely on gpio_desc pointer. - Create a list of instantiated platform devices to avoid any duplicates. - After creating reset-gpio platform device, try to get new reset controller or return EPROBE_DEFER. - Drop the "cookie" member and add new "of_args" to "struct reset_controller_dev". Description =========== We have at least few cases where hardware engineers decided to use one powerdown/shutdown/reset GPIO line for multiple devices: 1.

Johan [1] https://github.com/alsa-project/alsa-ucm-conf/pull/382 Changes in v2 - keep the volume register write on power-on in lpass-wsa-macro - drop the other patches removing volume register writes on DAPM events - only drop the constant-zero gain offsets in wcd9335 Johan Hovold (3): ASoC: qcom: sc8280xp: limit speaker volumes ASoC: codecs: lpass-wsa-macro: fix compander volume hack ASoC: codecs: wcd9335: drop unused gain hack remnant sound/soc/codecs/lpass-wsa-macro.c | 7 ------- sound/soc/codecs/wcd9335.c | 4 ---- sound/soc/qcom/sc8280xp.c | 8 +++++--- 3 files changed, 5 insertions(+), 14 deletions(-) -- 2.41.0

The following changes since commit 67508b874844b80ac49f70b78d67036c28b9fe7e: ASoC: pxa: sspa: Don't select SND_ARM (2023-12-29 17:41:15 +0000) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git tags/asoc-fix-v6.8-merge-window for you to fetch changes up to ab09fb9c629ed3aaea6a82467f08595dbc549726: ASoC: SOF: ipc4-loader: remove the CPC check warnings (2024-01-15 14:04:52 +0000) ---------------------------------------------------------------- ASoC: Fixes for v6.8 A bunch of small fixes that come in during the merge window, mainly fixing issues from some core refactoring around dummy components that weren't detected until things reached mainline. The TAS driver changes are a little larger than normal for a device ID addition due to some shuffling around of where things are registered and DT updates but aren't really any more substantial than normal. ---------------------------------------------------------------- AngeloGioacchino Del Regno (2): ASoC: mediatek: mt8195: Remove afe-dai component and rework codec link ASoC: mediatek: sof-common: Add NULL check for normal_link string ChiYuan Huang (2): ASoC: codecs: rtq9128: Fix PM_RUNTIME usage ASoC: codecs: rtq9128: Fix TDM enable and DAI format control flow Kai Vehmanen (1): ASoC: SOF: ipc4-loader: remove the CPC check warnings Kuninori Morimoto (1): ASoC: audio-graph-card2: fix index check on graph_parse_node_multi_nm() Mark Brown (1): rtq9128: Fix pm runtime and TDM usage Nícolas F.
