Discover a microphone device, to later discover if it is receiving input
by info 16 Oct '20

16 Oct '20

Hi all, I am writing a program that aims to auto-discover the microphone device that the user is speaking into. I started off by querying device hints and collected all devices with the IO types of null, since I have not found any devices with the type of Input. I am puzzled how it is possible that there is no Input, where a microphone device should not be able to emit sound. This is the list on my particular machine: Name of device: sysdefault:CARD=SB Description of device: HDA ATI SB, ALC892 Analog Default Audio Device I/O type of device: (null) Name of device: front:CARD=SB,DEV=0 Description of device: HDA ATI SB, ALC892 Analog Front speakers I/O type of device: (null) Name of device: surround21:CARD=SB,DEV=0 Description of device: HDA ATI SB, ALC892 Analog 2.1 Surround output to Front and Subwoofer speakers I/O type of device: Output Name of device: surround41:CARD=SB,DEV=0 Description of device: HDA ATI SB, ALC892 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers I/O type of device: Output Name of device: surround50:CARD=SB,DEV=0 Description of device: HDA ATI SB, ALC892 Analog 5.0 Surround output to Front, Center and Rear speakers I/O type of device: Output Name of device: surround71:CARD=SB,DEV=0 Description of device: HDA ATI SB, ALC892 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers I/O type of device: Output Name of device: sysdefault:CARD=SB Description of device: HDA ATI SB, ALC892 Analog Default Audio Device I/O type of device: (null) Name of device: front:CARD=SB,DEV=0 Description of device: HDA ATI SB, ALC892 Analog Front speakers I/O type of device: (null) Now, I am more puzzled, because none of them is a microphone device explicitly. How can my program determine which of them is actually a microphone? Also, why are devices are duplicated in the output from snd_device_name_hint()? The very first device is also repeated as the 2nd last one... Regards, Alex

[PATCH v3 00/13] Audio graph card updates and usage with Tegra210 audio
by Sameer Pujar 16 Oct '20

16 Oct '20

Summary of changes: * Support multiple instances of a component. For example there can be multiple I2S devices which can use the same component driver. * Support open platforms with empty Codec endpoint. Customers can plug their own HW and can populate codec endpoint. * In a component model there can be many components which can be connected togethe. In such cases Identify no-pcm DPCM DAI links which can be used in BE<->BE connections. * Add Tegra audio graph driver which is based on generic audio graph driver and specific customizations are done in Tegra driver. * This pushes DT support for Tegra210 based platforms which uses audio-graph card and above enhancements. The series is based on following references where DPCM usgae for Tegra Audio and simple-card driver proposal were discussed. * https://lkml.org/lkml/2020/4/30/519 (DPCM for Tegra) * https://lkml.org/lkml/2020/6/27/4 (simple-card driver) Changelog ========= v1 -> v2 -------- * Re-organized ports/endpoints description for ADMAIF and XBAR. Updated DT patches accordingly. * After above change, multiple Codec endpoint support is not required and hence dropped for now. This will be considered separately if at all required in future. * Re-ordered patches in the series. v2 -> v3 -------- * Dropped new compatible addition in generic graph driver after reviewing it with Morimoto-san. Instead added Tegra audio graph driver and new compatibles are added in the same. * Added new patches to expose new members for customization in audio graph driver. * Added new patch for Tegra audio graph driver and related documentation. * Minor change in below commit where mutex version of helper is used "ASoC: audio-graph: Identify 'no_pcm' DAI links for DPCM" * DT binding is updated to use the newly exposed compatibles * No changes in other patches Sameer Pujar (13): ASoC: soc-core: Fix component name_prefix parsing ASoC: soc-pcm: Get all BEs along DAPM path ASoC: audio-graph: Use of_node and DAI for DPCM DAI link names ASoC: audio-graph: Identify 'no_pcm' DAI links for DPCM ASoC: audio-graph: Support empty Codec endpoint ASoC: simple-card-utils: Expose new members for asoc_simple_priv ASoC: audio-graph: Update driver as per new exposed members ASoC: audio-graph: Expose helpers from audio graph ASoC: dt-bindings: tegra: Add schema for audio graph card ASoC: tegra: Add audio graph based card driver arm64: defconfig: Enable Tegra audio graph card driver arm64: tegra: Audio graph header for Tegra210 arm64: tegra: Audio graph sound card for Jetson Nano and TX1 .../sound/nvidia,tegra-audio-graph-card.yaml | 67 +++++ .../boot/dts/nvidia/tegra210-audio-graph.dtsi | 138 ++++++++++ arch/arm64/boot/dts/nvidia/tegra210-p2371-2180.dts | 219 ++++++++++++++++ arch/arm64/boot/dts/nvidia/tegra210-p3450-0000.dts | 124 +++++++++ arch/arm64/configs/defconfig | 1 + include/sound/graph_card.h | 19 ++ include/sound/simple_card_utils.h | 4 + include/sound/soc.h | 1 + sound/soc/generic/audio-graph-card.c | 92 +++++-- sound/soc/soc-core.c | 3 +- sound/soc/soc-pcm.c | 3 +- sound/soc/tegra/Kconfig | 9 + sound/soc/tegra/Makefile | 2 + sound/soc/tegra/tegra_audio_graph_card.c | 291 +++++++++++++++++++++ 14 files changed, 955 insertions(+), 18 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/nvidia,tegra-audio-graph-card.yaml create mode 100644 arch/arm64/boot/dts/nvidia/tegra210-audio-graph.dtsi create mode 100644 include/sound/graph_card.h create mode 100644 sound/soc/tegra/tegra_audio_graph_card.c -- 2.7.4

[PATCH 1/2] MAINTAINERS: Move Kukjin Kim to credits

Kukjin Kim has been maintaining the Samsung ARM architectures since 2010 up to 2016. He contributed many patches for the S3C, S5P and Exynos support. However since 2016 there is little activity from him on the LKML [1] so move his name to the CREDITS. Dear Kukjin, thank you for all the effort you put in to the upstream Samsung support.
