Subject: Re: [PATCH v6 01/14] ALSA: virtio: Propagate PCM send failures through ACK
Date: Wed, 28 Oct 2026 03:09:39 +0000 [thread overview]
Message-ID: <sashiko-outbox-187389@kernel.org> (raw)
In-Reply-To: <20261028025317.92450-2-mynameisjune111@gmail.com>
> 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.
>
> Fixes: fe981e67568c ("ALSA: virtio: use ack callback")
