How to support multi FIFO address in ALSA & DMA Engine?
by Shengjiu Wang 22 Apr '20

22 Apr '20

Hi Experts Some cpu-dai devices support multi FIFO, so we need to tell DMA which fifos and how many fifos it should fill the data to. For example, when channels = 2, only one fifo is used. when channels = 4, then two fifos are used. or when channels = 2, two fifos are used, when channels= 4, four fifos are used. But in snd_dmaengine_dai_dma_data, and dma_slave_config, there is only one dma address. Do you have any idea to support multi FIFO? is there any implemented reference? Best regards Wang shengjiu

[PATCH v2] ASoC: intel/skl/hda - fix oops on systems without i915 audio codec
by Kai Vehmanen 21 Apr '20

21 Apr '20

Recent fix for jack detection caused a regression on systems with HDA audio codec but no HDMI/DP audio via i915 graphics, leading to a kernel oops at device probe. On these systems, HDA bus instance lookup fails, as the first ASoC runtime of the card is connected to a dummy codec (as no HDMI codec is present).

[PATCH] ASoC: txx9: add back the hack for a too small resource_size_t

[PATCH v2 0/8] ASoC: add snd_compress_ops and replace
by Kuninori Morimoto 21 Apr '20

21 Apr '20

Hi Mark Current snd_soc_component_driver has compr_ops, but it is created for ALSA, not for ALSA SoC. This means it doesn't know the callback is for which component, thus, each callback needs to get component via lookup function. It is not good design, and will not work in the future, because ASoC can have multipul same name component which current lookup function can't handle. This v2 patch-set adds new snd_compress_ops and call callbacks with component. v1 is here Link: https://lore.kernel.org/alsa-devel/87blnqpuqp.wl-kuninori.morimoto.gx@renes… Kuninori Morimoto (8): ASoC: soc-compress: add snd_compress_ops ASoC: codec: wm_adsp: use snd_compress_ops ASoC: uniphier: use snd_compress_ops ASoC: qcom: q6sp6: use snd_compress_ops ASoC: intel: atom: use snd_compress_ops ASoC: sof: use snd_compress_ops ASoC: sprd: use snd_compress_ops ASoC: soc-compress: remove snd_compr_ops include/sound/soc-component.h | 40 ++++++++- sound/soc/codecs/cs47l15.c | 9 +- sound/soc/codecs/cs47l24.c | 8 +- sound/soc/codecs/cs47l35.c | 9 +- sound/soc/codecs/cs47l85.c | 9 +- sound/soc/codecs/cs47l90.c | 9 +- sound/soc/codecs/cs47l92.c | 9 +- sound/soc/codecs/wm5102.c | 9 +- sound/soc/codecs/wm5110.c | 8 +- sound/soc/codecs/wm_adsp.c | 18 ++-- sound/soc/codecs/wm_adsp.h | 18 ++-- .../intel/atom/sst-mfld-platform-compress.c | 43 +++++---- sound/soc/intel/atom/sst-mfld-platform-pcm.c | 2 +- sound/soc/intel/atom/sst-mfld-platform.h | 2 +- sound/soc/qcom/qdsp6/q6asm-dai.c | 51 ++++++----- sound/soc/soc-compress.c | 89 ++++++++++--------- sound/soc/sof/compress.c | 7 +- sound/soc/sof/compress.h | 7 +- sound/soc/sof/pcm.c | 4 +- sound/soc/sof/sof-priv.h | 2 +- sound/soc/sprd/sprd-pcm-compress.c | 49 +++++----- sound/soc/sprd/sprd-pcm-dma.c | 2 +- sound/soc/sprd/sprd-pcm-dma.h | 2 +- sound/soc/uniphier/aio-compress.c | 45 ++++++---- sound/soc/uniphier/aio-dma.c | 2 +- sound/soc/uniphier/aio.h | 2 +- 26 files changed, 265 insertions(+), 190 deletions(-) -- 2.17.1

[PATCH] ASoC: wm8960: Fix wrong clock after suspend & resume
by Shengjiu Wang 21 Apr '20

21 Apr '20

After suspend & resume, wm8960_hw_params may be called when bias_level is not SND_SOC_BIAS_ON, then wm8960_configure_clocking is not called. But if sample rate is changed at that time, then the output clock rate will be not correct. So judgement of bias_level is SND_SOC_BIAS_ON in wm8960_hw_params is not necessary and it causes above issue.
