[v3,0/5] drm/i915: ttm for stolen region

Message

Bob Beckett April 12, 2022, 7:38 p.m. UTC

This series refactors i915's stolen memory region to use ttm.

v2:	handle disabled stolen similar to legacy version.
	relying on ttm to fail allocs works fine, but is dmesg noisy and causes testing
	dmesg warning regressions.

v3:	rebase to latest drm-tip.
	fix v2 code refactor which could leave a buffer pinned.
	locally passes fftl again now.

Robert Beckett (5):
  drm/i915: instantiate ttm ranger manager for stolen memory
  drm/i915: sanitize mem_flags for stolen buffers
  drm/i915: ttm move/clear logic fix
  drm/i915: ttm backend dont provide mmap_offset for kernel buffers
  drm/i915: stolen memory use ttm backend
