[PATCH 0/7] ASoc: Another series to convert to struct platform_driver:remove_new()
by Uwe Kleine-König 24 Oct '23

24 Oct '23

Hello, this is another series to convert ASoC drivers to use struct platform_driver:remove_new(). The rockchip one was already send before but with a wrong subject prefix, the cs42l43 driver is newer than the last series. The remaining five patches are for driver combos that my coccinelle patch failed to detect before.

[PATCH v3] ALSA: virtio: use ack callback
by Matias Ezequiel Vara Larsen 24 Oct '23

24 Oct '23

This commit uses the ack() callback to determine when a buffer has been updated, then exposes it to guest. The current mechanism splits a dma buffer into descriptors that are exposed to the device. This dma buffer is shared with the user application. When the device consumes a buffer, the driver moves the request from the used ring to available ring. The driver exposes the buffer to the device without knowing if the content has been updated from the user. The section 2.8.21.1 of the virtio spec states that: "The device MAY access the descriptor chains the driver created and the memory they refer to immediately". If the device picks up buffers from the available ring just after it is notified, it happens that the content may be old. When the ack() callback is invoked, the driver exposes only the buffers that have already been updated, i.e., enqueued in the available ring. Thus, the device always picks up a buffer that is updated. For capturing, the driver starts by exposing all the available buffers to device. After device updates the content of a buffer, it enqueues it in the used ring. It is only after the ack() for capturing is issued that the driver re-enqueues the buffer in the available ring.

[PATCH v2] ALSA: virtio: use copy and fill_silence callbacks
by Matias Ezequiel Vara Larsen 24 Oct '23

24 Oct '23

This commit replaces the mmap mechanism with the copy() and fill_silence() callbacks for both capturing and playback for the virtio-sound driver. This change is required to prevent the updating of the content of a buffer that is already in the available ring. The current mechanism splits a dma buffer into descriptors that are exposed to the device. This dma buffer is shared with the user application. When the device consumes a buffer, the driver moves the request from the used ring to available ring. The driver exposes the buffer to the device without knowing if the content has been updated from the user. The section 2.8.21.1 of the virtio spec states that: "The device MAY access the descriptor chains the driver created and the memory they refer to immediately". If the device picks up buffers from the available ring just after it is notified, it happens that the content may be old. By providing the copy() callback, the driver first updates the content of the buffer, and then, exposes the buffer to the device by enqueuing it in the available ring. Thus, device always picks up a buffer that is updated. During copy(), the number of requests enqueued depends on the "pos" and "bytes" arguments. The length of each request is period_size bytes. For capturing, the driver starts by exposing all the available buffers to device. After device updates the content of a buffer, it enqueues it in the used ring. It is only after the copy() for capturing is issued that the driver re-enqueues the buffer in the available ring.

[PATCH v3 0/4] ASoC: makes CPU/Codec channel connection map more generic
by Kuninori Morimoto 23 Oct '23

23 Oct '23

Hi Mark Cc Bard, Pierre-Louis, DT-ML This is v3 patch-set. Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using ch_map idea. This patch-set expands it that all connection uses this idea, and no longer N < M limit [1]. Link: https://lore.kernel.org/r/87fs6wuszr.wl-kuninori.morimoto.gx@renesas.com [1] This patch is tested on Audio-Graph-Card2 with sample dtsi, but needs Tested-by, at least from Intel. v2 -> v3 - tidyup comment - use more clear connection image on DT - "ch_maps" -> "ch-maps" on DT - Add DT maintainer on "To:" for all patches v1 -> v2 - makes CPU/Codec connection relation clear on comment/sample - fixup type "connction" -> "connection" - makes error message clear Kuninori Morimoto (4): ASoC: makes CPU/Codec channel connection map more generic ASoC: audio-graph-card2: add CPU:Codec = N:M support ASoC: audio-graph-card2-custom-sample: add CPU/Codec = N:M sample dt-bindings: audio-graph-port: add ch-maps property .../bindings/sound/audio-graph-port.yaml | 2 + include/sound/soc.h | 66 ++++++++- .../audio-graph-card2-custom-sample.dtsi | 138 +++++++++++++++--- sound/soc/generic/audio-graph-card2.c | 29 ++++ sound/soc/intel/boards/sof_sdw.c | 14 +- sound/soc/soc-core.c | 85 +++++++++++ sound/soc/soc-dapm.c | 47 +++--- sound/soc/soc-pcm.c | 73 ++++----- 8 files changed, 363 insertions(+), 91 deletions(-) -- 2.25.1

[PATCH] ASoC: soc-core.c: Log components string to help with UCM profile development
by Hans de Goede 22 Oct '23

22 Oct '23

Various ASoC board/card drivers use a components string to communicate to userspace which output (speakers / headphones) and input (internal mic / headset mic) routes have been setup by the card driver so that the UCM profiles can dynamically adjust to this. ATM it is sort of hard to figure out what the component string has actually been set to by the kernel. Log the components string set on the snd_soc_card to help with UCM profile development.
