[CI 0/2] drm/mm: Add an iterator to optimally walk over holes suitable for an allocation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The first patch is a drm core patch that replaces the for loop in
drm_mm_insert_node_in_range() with the iterator and would not
cause any functional changes. The second patch is a i915 driver
specific patch that also uses the iterator but solves a different
problem.

v2:
- Added a new patch to this series to fix a potential NULL
  dereference.
- Fixed a typo associated with the iterator introduced in the
  drm core patch.
- Added locking around the snippet in the i915 patch that
  traverses the GGTT hole nodes.

v3: (Tvrtko)
- Replaced mutex_lock with mutex_lock_interruptible_nested() in
  the i915 patch.

v4: (Tvrtko)
- Dropped the patch added in v2 as it was deemed unnecessary.
