This series continues support for 64K pages for discrete cards.
It supersedes the 64K patches from https://patchwork.freedesktop.org/series/95686/#rev4
Changes since that series:
- set min alignment for DG2 to 2MB in i915_address_space_init
- replace coloring with simpler 2MB VA alignment for lmem buffers
- enforce alignment to 2MB for lmem objects on DG2 in i915_vma_insert
- expand vma reservation to round up to 2MB on DG2 in i915_vma_insert
- add alignment test
v2: rebase and fix for async vma that landed
v3:
* fix uapi doc typos
* add needs_compact_pt flag patch
* cleanup vma expansion to use vm->min_alignment instead of hard coding
