drm/xe: Update GuC/HuC firmware autoselect logic
Update the logic to autoselect GuC/HuC for the platforms with the
following improvements:
- Document what is the firmware file that is expected to be
loaded and what is checked from blob headers
- When the platform is under force-probe it's desired to enforce
the full-version requirement so the correct firmware is used
before widespread adoption and backward-compatibility
commitments
- Directory from which we expect firmware blobs to be available in
upstream linux-firmware repository depends on the platform: for
the ones supported by i915 it uses the i915/ directory, but the ones
expected to be supported by xe, it's on the xe/ directory. This
means that for platforms in the intersection, the firmware is
loaded from a different directory, but that is not much important
in the firmware repo and it avoids firmware duplication.
- Make the table with the firmware definitions clearly state the
versions being expected. Now with macros to select the version it's
possible to choose between full-version/major-version for GuC and
full-version/no-version for HuC. These are similar to the macros used
in i915, but implemented in a slightly different way to avoid
duplicating the macros for each firmware/type and functionality,
besides adding the support for different directories.
- There is no check added regarding force-probe since xe should
reuse the same firmware files published for i915 for past
platforms. This can be improved later with additional
kunit checking against a hardcoded list of platforms that
falls in this category.
- As mentioned in the TODO, the major version fallback was not
implemented before as currently each platform only supports one
major. That can be easily added later.
- GuC version for MTL and PVC were updated to 70.6.4, using the exact
full version, while the
After this the GuC firmware used by PVC changes to pvc_guc_70.5.2.bin
since it's using a file not published yet.
