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 v4: * fix err return in igt_ppgtt_compact test * placate ci robot with explicit enum conversion in misaligned_pin * remove some blank lines v5: * fix obj alignment requirements querying for internal buffers that have no memory region associated. (fixes v3 bug)
