Subject: [PATCH 0/5] drm/i915/dmc: firmware path handling changes
Date: Thu, 18 Apr 2024 17:39:49 +0300	[thread overview]
Message-ID: <cover.1713450693.git.jani.nikula@intel.com> (raw)

We tried moving the dmc_firmware_path param from i915 to display params
before, so it would be present in xe as well as i915. This was commit
0d82a0d6f556 ("drm/i915/display: move dmc_firmware_path to display
params"). That failed, so I tried a quick fix, but that failed too
[1]. Revert followed in commit 318e82583ca9 ("Revert "drm/i915/display:
move dmc_firmware_path to display params"").

Do some refactoring and prep work first, with the most significant
change being the removal of special handling of
i915.dmc_firmware_path="" to disable DMC. This will now lead to the
platform default firmware being used.

To disable DMC and runtime PM, you'll need to specify a non-existent
file instead. There's no "magic" name specified for that.

BR,
Jani.
