[alsa-devel] [PATCH 0/8] ALSA: pcm: API cleanups and extensions
by Takashi Iwai 22 Nov '19

22 Nov '19

Hi, this is a patch series for a few ALSA PCM API changes. Basically the patch set introduces three changes: * Add the "managed buffer allocation" mode; this allows many drivers to drop hw_params and hw_free callbacks that simply call snd_pcm_lib_malloc_pages() and *_free_pages(). * Make PCM ioctl ops optional; almost all driver can drop the lines to define pcm_ops.ioctl. * The new sync_stop PCM ops and card->sync_irq; it's used to synchronize the pending task after stopping the stream, for fixing the use-after-free or such problem. I planned originally merging these changes to 5.6. But since the API changes would influence on many drivers outside sound git tree, it might be easier to merge only these core changes at first during 5.5 merge window while keeping the rest (the actual driver implementations) intact -- that's why I post now for reviews. The changes are additional, and they won't break things by themselves. The drivers can / need to change the call patterns for following these new APIs. thanks, Takashi === Takashi Iwai (8): ALSA: pcm: Introduce managed buffer allocation mode ALSA: docs: Update for managed buffer allocation mode ALSA: pcm: Allow NULL ioctl ops ALSA: docs: Update document about the default PCM ioctl ops ALSA: pcm: Move PCM_RUNTIME_CHECK() macro into local header ALSA: pcm: Add the support for sync-stop operation ALSA: pcm: Add card sync_irq field ALSA: docs: Update about the new PCM sync_stop ops .../sound/kernel-api/writing-an-alsa-driver.rst | 148 +++++++++++++++------ include/sound/core.h | 1 + include/sound/pcm.h | 12 +- sound/core/init.c | 1 + sound/core/pcm_local.h | 2 + sound/core/pcm_memory.c | 83 ++++++++++-- sound/core/pcm_native.c | 48 ++++++- 7 files changed, 237 insertions(+), 58 deletions(-) -- 2.16.4

alsa-project/alsa-lib issue #14 was edited from bharris6: When using the [ALSA File plugin](https://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html) you can tell it to pipe playback data to either a file or a program/shell command. >Output filename (or shell command the stream will be piped to if STR starts with the pipe char).

[alsa-devel] [RESEND PATCH v11 3/6] ASoC: amd: Enabling I2S instance in DMA and DAI
by Ravulapati Vishnu vardhan rao 21 Nov '19

21 Nov '19

This patch adds I2S SP support in ACP PCM DMA and DAI. Added I2S support in DMA and DAI probe,its hw_params handling its open and close functionalities. This enable to open and close on the SP instance for playback and capture.

[alsa-devel] [RESEND PATCH v11 6/6] ASoC: amd: Added ACP3x system resume and runtime pm
by Ravulapati Vishnu vardhan rao 21 Nov '19

21 Nov '19

When system wide suspend happens, ACP will be powered off and when system resumes,for audio usecase to continue,all the runtime configuration data needs to be programmed again. Added resume pm call back to ACP pm ops and also added runtime PM operations for ACP3x PCM platform device. Device will enter into D3 state when there is no activity on audio I2S lines.

[alsa-devel] [RESEND PATCH v11 5/6] ASoC: amd: Handle ACP3x I2S-SP Interrupts.
by Ravulapati Vishnu vardhan rao 21 Nov '19

21 Nov '19

Enabled support for I2S-SP interrupt handling. Previous to this implementation, driver supports only interrupts on BT instance.
