[PATCH 1/4] ASoC: SOF: pcm: skip DMA buffer pre-allocation

[Pierre-Louis Bossart]

From: Keyon Jie <yang.jie@linux.intel.com>

As discussion in ALSA https://patchwork.kernel.org/patch/11336023/, it
is suggested to skip DMA buffer pre-allocation with passing size=0 when
calling snd_pcm_set_managed_buffer(), to make the full buffer_bytes
range configured in topology file selectable from user space, here do
the corresponding change in SOF PCM driver to implement it.

This change doesn't have dependency to the change that Takashi will do
in the ALSA core by adding total_pcm_alloc_bytes limitation to the
struct snd_card, it passes tests both with or without Takashi's coming
change on SOF CML platform.

Applied "ASoC: SOF: pcm: skip DMA buffer pre-allocation" to the asoc tree

[Mark Brown]

The patch

   ASoC: SOF: pcm: skip DMA buffer pre-allocation

has been applied to the asoc tree at

   https://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

[PATCH 2/4] ASoC: SOF: ipc: check ipc return value before data copy

[Pierre-Louis Bossart]

From: Jaska Uimonen <jaska.uimonen@linux.intel.com>

In tx_wait_done the ipc payload is copied before the DSP transaction
error code is checked. This might lead to corrupted data in kernel side
even though the error would be handled later. It is also pointless to
copy the data in case of error. So change the order of error check and
copy.

[PATCH 4/4] ASoC: SOF: add core id to sof_ipc_comp

[Pierre-Louis Bossart]

From: Tomasz Lauda <tomasz.lauda@linux.intel.com>

Adds core id to sof_ipc_comp. The intention of this change
is to inform FW on which core that particular component
should run. Right now core id is only passed when pipeline
is created, which is not flexible enough and doesn't allow
for FW to handle this the right way.
