[Intel-xe] [PATCH 0/9] Refactor kernel setting of PAT

[Lucas De Marchi]

This reworks how we set PAT bits in both PPGTT and GGTT with the kernel
users in mind only. Allowing to set PAT by userspace is being added by
https://lore.kernel.org/all/20230829162840.73444-7-matthew.auld@intel.com/T/.
This can be seen as a follow up to the WIP patch that series depends on,
https://patchwork.freedesktop.org/series/122708/

I'm using that patch as a starting point, but as noted in my review
comments there, I think the overall abstraction we had and the ones we
were adding were not optimal. This is my attempt to translate my review
comments into the abstraction I was thinking of.

Lightly tested on DG2.

Lucas De Marchi (9):
  drm/xe: Normalize pte/pde encoding
  drm/xe: Remove check for vma == NULL
  drm/xe: Use vfunc for pte/pde ppgtt encoding
  drm/xe/migrate: Do not hand-encode pte
  drm/xe: Use vfunc to initialize PAT
  drm/xe/pat: Keep track of relevant indexes
  drm/xe: Use pat_index to encode pte
  drm/xe: Use vfunc for ggtt pte encoding
  fixup! drm/xe/display: Implement display support
