Bug description:
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.
