Public bug reported:

[Impact]

Ubuntu 22.04 does not support Intel DG2-based hw which is released later
this year.


[Fix]

Mesa: needs a bunch of patches backported to 22.0.x, will be upstream in 22.1 
or 22.2
kernel: use a dkms provided by Intel and integrated in the OEM kernel source, 
the module will be shipped in a separate modules package


[Test case]

Boot a system with a DG2-based GPU, check that native graphics drivers
are used


[What could go wrong]

The Mesa patches are only for DG2 support, should not affect other
hardware at all. The kernel driver is in a separate package which isn't
installed by default except preinstall machines with this hardware. So
other users are not affected.
