[igt-dev] [PATCH i-g-t v3 05/28] i915/perf: Skip sseu-config tests for gfx12.50+

[Umesh Nerlige Ramappa]

On Gen11, the Media driver will need to limit dispatch to only big
subslices (usually half the EUs depending on EU fusing). If media,
render and OA are running in parallel, then OA will lose the NOA config
because half of the EUs will be turned off by media. To avoid this with
concurrent use cases, an sseu config to keep all EUs powered on is
passed to OA in the i915_perf_open_ioctl params. This configuration is
made part of the render contexts, so that it's applied when 3d contexts
are running. Since this is an issue on gen11, skip sseu-config tests on
other platforms.

v2:
- While sseu-config is only applicable gen11, gfx12 is already shipped
  with this, so skip the test only for gfx12.50+
