Subject: [Intel-gfx] [PATCH 0/2] Use unversioned blob path for ADLP DMC
Date: Mon, 23 Jan 2023 15:20:19 -0300	[thread overview]
Message-ID: <20230123182021.31239-1-gustavo.sousa@intel.com> (raw)

This series introduces the use of unversioned blob path for ADLP DMC,
which begins using the new convention as of v2.18.

In order not to cause regressions with systems not having linux-firmware
up to date, we recall a patch from [1] that adds a fallback mechanism to
load from the latest versioned path in case the unversioned one is not
found.

IMPORTANT: Prior to applying this, we need to wait for a PR to
linux-firmware with the proper update to be applied. I will create such
PR after this series is accepted and CI results are good.
