Subject: [PATCH 0/2] ALSA: compress: clean up pointer errno handling and fix avail errors
Date: Tue, 14 Apr 2026 13:47:52 -0300 [thread overview]
Message-ID: <20260414-alsa-compress-pointer-avail-errors-v1-0-f5a1a8b1dfba@gmail.com> (raw)
This series tightens compressed-offload pointer error handling in two
small steps.
Patch 1 switches the internal "pointer callback not implemented" case
from ENOTSUPP to EOPNOTSUPP so the code uses the standard unsupported
operation errno.
Patch 2 then propagates real pointer-refresh failures through the avail
paths while keeping the unsupported-pointer fallback non-fatal. This
prevents SNDRV_COMPRESS_AVAIL, read(), write(), and poll() from
continuing with stale availability data after real pointer errors.
