Re: [PATCH v9 01/14] ALSA: virtio: Propagate PCM send failures through ACK
flat view
From: sashiko-bot@kernel.org
Date: 2026-10-29 09:14:57
virtsnd_pcm_msg_send() can fail while queueing a transfer. Restore the
failed message's length and notify the device about earlier messages
queued by the same call, so they do not remain stranded.
Propagate that failure through the indirect PCM transfer callback instead
of discarding it. Commit the updated indirect state only after successful
submission and stop further transfers when a send fails. Return an XRUN
error to ALSA so the stream can recover.
Keep the polling feature path unchanged.
