Subject: [PATCH] modules/firmware: add a new option to denote a firmware group to choose one.
Date: Wed, 19 Apr 2023 14:36:52 +1000 [thread overview]
Message-ID: <20230419043652.1773413-1-airlied@gmail.com> (raw)
From: Dave Airlie <airlied@redhat.com>
This adds a tag that will go into the module info, only one firmware from
the group given needs to be available for this driver to work. This allows
dracut to avoid adding in firmware that aren't needed.
This just brackets a module list in the modinfo, the modules in the list
will get entries in reversed order so the last module in the list is the
preferred one.
The corresponding dracut code it at:
