[alsa-devel] [PATCH v2 00/13] ASoC: Intel: Skylake: Driver updates
From: Jeeja KP jeeja.kp@intel.com
This patch series includes driver updates for the handling scenarios during System S0/S3 transitions when audio stream is stopped during system. o move DMA configuration in DSP Gateway Module widget event handler to ensure DMA is configured after resume. o Enable SSP MLCK using Supply widget. This will ensure the MCLK is enabled when the widget is power on. o Check DMA decouple register state before coupling/decoupling the DMA. o In case of HDMI pass-through pipe, reset only the FE Pipe when stream in in XRUN state. o Resume the stream from HW renderer position. o HDMI Codec pin and converter state need to be restored when stream is resumed.
Changes in v2: - Addressed Mark's comment on patch 1, split this into 2 as this had additional changes other than configuring the DMA. - Addressed Takashi's comment on the usage of snd_hdac_updatel()

To configure Host/Link DMA, additionally link index and format are required based on the hw params. So added these parameters in the pipe params and in hw_params the pipe params are updated.

The patch
ASoC: Intel: Skylake: Update link_index and format in pipe params
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

This patch adds helper function to configure the host/link DMA when the DMA is in decoupled mode. Next patch adds the usage of this helper routines for configuring DMA in Mixer event handler.

If system is suspended when PCM was paused/stopped, restart doesn't configure DMA as it is we are in Pause state and results in IO error eventually.
Configure host/link DMA before initializing DSP Gateway copier module instead of DAI prepare(). So moved DMA configuration to mixer PRE_PMD widget handler instead of DAI prepare.
This uses previously added new API to do the configuration and removes old DAI prepare code.

Some machine requires MCLK to be enabled before SSP start up, so add set_tristate() DAI ops to enable/disable SSP MCLK. This ops will be called from machine which requires early MCLK and removes the usage of enabling early MLCK in platform DAI prepare by default which is not machine specific.

In system suspend, the firmware pipelines will be deleted and there is no need to save the pipeline context. Driver will save the DPIB and LPIB pointers in suspend.
In system resume, the firmware pipelines will be created again and the RD/RW pointers in the Firmware buffer points to the base address. So need to fetch the non-played data again to firmware buffer. LPIB indicates the HW rendered position.
Instead of setting DPIB as resume point, set it to LPIB to restore from the HW render position so that DMA would fetch the non-played data one more time.
