Re: [PATCH v32 07/20] ALSA: virtio: Recover PCM state after a failed start

[sashiko-bot@kernel.org]

> From: Joonho Lee <mynameisjune111@gmail.com>
> 
> Capture trigger queues I/O messages before PCM_START. If the START
> message cannot be allocated or sent, transfers may remain queued, and
> ALSA does not invoke the action undo callback for the failed trigger.
> 
> Mark the stream stopped and disable transfers for every failed START
> path. Arm runtime->stop_operating so sync_stop releases pending I/O and
> prevents prepare, hw_params, or START retries until release succeeds.
> 
> Latch a transfer XRUN in both playback and capture, and schedule the
> existing period worker so a running or draining core stream sees the
> pointer error. This also retires a failed playback START during drain,
> where drain-init can already have advanced the core state to DRAINING.

> [ ... ]
> wait without submitting RELEASE again.
