Subject: [PATCH v1 0/3] drm_buddy regresion fix and minor improvements
Date: Wed, 2 Jul 2025 18:12:01 +0200	[thread overview]
Message-ID: <20250702161208.25188-1-pierre-eric.pelloux-prayer@amd.com> (raw)

Hi,

The first patch fixes a performance issue caused by a change in
drm_buddy ("drm/buddy: Implement tracking clear page feature").
It may be related to https://gitlab.freedesktop.org/drm/amd/-/issues/4260.

The other 2 patches are improvements based on my limited understanding
of the code and that seem to work as expected.


Pierre-Eric Pelloux-Prayer (3):
  drm/buddy: add a flag to disable trimming of non cleared blocks
  drm/buddy: use DRM_BUDDY_CLEAR_ALLOCATION as a hint, not a hard req
  drm/buddy: dont go over the higher orders multiple times
