[alsa-devel] Applied "ASoC: SOF: Intel: only support INFO_BATCH for legacy platforms" to the asoc tree

[Mark Brown]

The patch

   ASoC: SOF: Intel: only support INFO_BATCH for legacy platforms

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

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

Subject: [PATCH] ASoC: SOF: Intel: only support INFO_BATCH for legacy
 platforms

The current position update is not precise enough for PulseAudio to
work reliably with the timer-based scheduling on Baytrail,
Cherrytrail, Broadwell.

Disable the NO_PERIOD_WAKEUP capability and use BATCH to signal that
the position is only reliable and updated during period_elapsed
events.

This will be reverted when the firmware provides a more accurate
position for those platforms.
