[Intel-gfx] [PATCH v3 0/5] discrete card 64K page support

[Robert Beckett]

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

  drm/i915: enforce min GTT alignment for discrete cards
  drm/i915: support 64K GTT pages for discrete cards
  drm/i915/uapi: document behaviour for DG2 64K support

Ramalingam C (1):
  drm/i915: add needs_compact_pt flag

Robert Beckett (1):
  drm/i915: add gtt misalignment test
