[Intel-xe] [PATCH v3 0/3] drm/helpers: Make the suballocation manager drm generic

[Thomas Hellström]

This series (or at least the suballocator helper) is a prerequisite
for the new Xe driver.

There was an unresolved issue when the series was last up for review,
and that was the per allocation aligment. Last message was from
Maarten Lankhorst arguing that the larger per-driver alignment used
would only incur a small memory cost. This new variant resolves that.

The generic suballocator has been tested with the Xe driver, and a
kunit test is under development.
The amd- and radeon adaptations are only compile-tested.

v3:
- Remove stale author information (Christian König)
- Update Radeon Kconfig (Thomas Hellström)


Maarten Lankhorst (3):
  drm/suballoc: Extract amdgpu_sa.c as generic suballocation helper
  drm/amd: Convert amdgpu to use suballocation helper.
  drm/radeon: Use the drm suballocation manager implementation.
