These are cherry-picks from the xe shrinker series here:
https://patchwork.freedesktop.org/series/131815/
extracted to speed up review progress and inclusion.
The series provides a restartable LRU walk and makes it possible
resume the walk after dropping the lock to evict or swap out.
Patch 1-4 implements restartable LRU list iteration.
Patch 5 implements a LRU walker + resv locking helper
Patch 6 moves TTM swapping over to the walker.
Patch 7 moves TTM eviction over to the walker.
Patch 8 Balances the struct ttm_resource_cursor interface
v2:
- Squash obsolete revision history in the patch commit messages.
- Fix a couple of review comments by Christian
- Don't store the mem_type in the TTM managers but in the
resource cursor.
- Rename introduced TTM *back_up* function names to *backup*
- Add ttm pool recovery fault injection.
- Shrinker xe kunit test
- Various bugfixes
v3:
- Address some review comments from Matthew Brost and Christian König.
- Use the restartable LRU walk for TTM swapping and eviction.
- Provide a POC drm_exec locking implementation for exhaustive
eviction. (Christian König).
v4:
- Remove the RFC exhaustive eviction part. While the path to exhaustive
eviction is pretty clear and demonstrated in v3, there is still some
drm_exec work that needs to be agreed and implemented.
- Add shrinker power management. On some hw we need to wake when shrinking.
- Fix the lru walker helper for -EALREADY errors.
- Add drm/xe: Increase the XE_PL_TT watermark.
v5:
- Update also TTM kunit tests
- Handle ghost- and zombie objects in the shrinker.
- A couple of compile- and UAF fixes reported by Kernel Build Robot and
Dan Carpenter.
v6:
- Address review comments from Matthew Brost as detailed in patches
4/12, 5/12, 6/12, 7/12, 8/12.
v7:
- Drop previous patches 8-12 for now and concentrate on 1-7
- Add a new patch 8 to balance the ttm_resource_cursor interface
(Christian König)
- Fix various style comments from Christian König in patch 5-7.
- Update Reviewed-by: and Acked tags.
