[PATCH] sound: make all 'class' structures const
by Greg Kroah-Hartman 21 Jun '23

21 Jun '23

From: Ivan Orlov <ivan.orlov0322(a)gmail.com> Now that the driver core allows for struct class to be in read-only memory, making all 'class' structures to be declared at build time placing them into read-only memory, instead of having to be dynamically allocated at load time.

[PATCH v3] ALSA: compress: allow setting codec params after next track
by Srinivas Kandagatla 21 Jun '23

21 Jun '23

For gapless playback it is possible that each track can have different codec profile with same decoder, for example we have WMA album, we may have different tracks as WMA v9, WMA v10 and so on Or if DSP's like QDSP have abililty to switch decoders on single stream for each track, then this call could be used to set new codec parameters. Existing code does not allow to change this profile while doing gapless playback. Reuse existing SNDRV_COMPRESS_SET_PARAMS to set this new track params along some additional checks to enforce proper state machine. With this new changes now the user can call SNDRV_COMPRESS_SET_PARAMS anytime after setting next track and additional check in write should also ensure that params are set before writing new data.

[PATCH V4 0/9] ASoC: amd: ps: add SoundWire support
by Vijendar Mukunda 21 Jun '23

21 Jun '23

This patch series add support for - Platform device creation for SoundWire Manager instances and PDM controller. - SoundWire DMA driver. - Interrupt handling for SoundWire manager related interrupts, SoundWire DMA interrupts and ACP error interrupts. - ACP PCI driver PM ops modification with respect to SoundWire Power modes. Changes since v3: - use pdev_config instead of pdev_mask in the code. - define platform device configuration macros rather than enums - add comments for MIPI DisCo version - refactor SoundWire DMA start/stop sequence using single function - refactor "acp_reset" flag related functionality. Changes since v2: - add comments in irq handler. - remove workqueue for SoundWire DMA interrupts and use thread implementation for DMA interrupt handling. - add error checks in sdw_amd_scan_controller() - remove passing "acp_lock" as platform resource for SoundWire DMA driver and PDM driver. - retrieve "acp_lock" reference from parent driver directly and use the reference in SoundWire DMA driver. - add handling for acp pci driver probe even when no ACP PDM or SoundWire manager platform devices created. - Fix indentation for acp_sdw_dma_count structure variables. - Use macro instead of hard coded values for FIFO offset and PTE offset. - Change pm_runtime enable sequence in SoundWire DMA driver probe function. - Refactor system level resume callback in SoundWire DMA Changes since v1: - update "soundwire" as "SoundWire" in code. - add comments for platform device mask and platform device count - remove unused variables in acp pci driver private data structure - refactor dma enable register structures in SoundWire DMA driver - add TODO comments in IRQ handler - update IRQ mask values using bit macros - Fix build error reported in Makefile - rename "sdw_dma_stream_instance" structure name as "acp_sdw_dma_stream" Vijendar Mukunda (9): ASoC: amd: ps: create platform devices based on acp config ASoC: amd: ps: handle SoundWire interrupts in acp pci driver ASoC: amd: ps: add SoundWire dma driver ASoC: amd: ps: add SoundWire dma driver dma ops ASoC: amd: ps: add support for SoundWire DMA interrupts ASoC: amd: ps: add pm ops support for SoundWire dma driver ASoC: amd: ps: enable SoundWire dma driver build ASoC: amd: update comments in Kconfig file ASoC: amd: ps: add acp_reset flag check in acp pci driver pm ops. sound/soc/amd/Kconfig | 3 +- sound/soc/amd/ps/Makefile | 2 + sound/soc/amd/ps/acp63.h | 172 ++++++++++- sound/soc/amd/ps/pci-ps.c | 419 +++++++++++++++++++++++-- sound/soc/amd/ps/ps-sdw-dma.c | 555 ++++++++++++++++++++++++++++++++++ 5 files changed, 1115 insertions(+), 36 deletions(-) create mode 100644 sound/soc/amd/ps/ps-sdw-dma.c -- 2.34.1

Hi Mark Current soc-core.c has snd_soc_{of_}get_dai_name() to get DAI name for dlc (snd_soc_dai_link_component). It gets .dai_name, but we need .of_node too. Therefor user need to arrange. It will be more useful if it gets both .dai_name and .of_node.
