Bug Description
[SRU Justification:
[Impact]
It shows the firmware is missing, and runtime power management has been
disabled:
i915 0000:00:02.0: [drm] Failed to load DMC firmware
i915/
[Fix]
Upstream commit 3d32f216 ("i915: Add ADL-P DMC Support").
[Test Case]
Verified on Intel ADL-M/ADL-P RVPs.
[Where problems could occur]
It's a new firmware for new GPU, not possible to introduce regressions.
[Other Info]
Impish has this already. And while ADL-P/M support begins since v5.14,
only focal (for oem-5.14) is being nominated.
=======
[SRU Justification:
NOTE: this is for focal only, hirsute/impish do not and will not have kernel support for this.
[Impact]
ADL-P machines need to use the native driver.
[Fix]
Backport support from upstream.
libdrm: a single patch from 2.4.107
mesa: three commits to add pci-id's and a workaround
kernel: needs drm sync from 5.14 (bug 1940085) plus additional backports
[Test case]
Boot a machine and check that it's using the native driver and that the usual workloads are fine.
[Where things could go wrong]
For older gpu's there's little to go wrong, since the commits are for ADL-P only.
