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.
