Subject: [PATCH v5 0/3] Add option to mmap GEM buffers cached
Date: Sun, 23 May 2021 18:04:12 +0100 [thread overview]
Message-ID: <20210523170415.90410-1-paul@crapouillou.net> (raw)
V5 of my patchset which adds the option for having GEM buffers backed by
non-coherent memory.
Changes from V4:
- [2/3]:
- Rename to drm_fb_cma_sync_non_coherent
- Invert loops for better cache locality
- Only sync BOs that have the non-coherent flag
- Properly sort includes
- Move to drm_fb_cma_helper.c to avoid circular dependency
- [3/3]:
- Fix drm_atomic_get_new_plane_state() used to retrieve the old
state
- Use custom drm_gem_fb_create()
- Only check damage clips and sync DMA buffers if non-coherent
buffers are used
Cheers,
-Paul
