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
I'm pretty sure it's still not the right place. That would be something like drm_gem_cma_atomic_helper.c, but creating a new file just for a single function doesn't make sense.
- [3/3]:
- Fix drm_atomic_get_new_plane_state() used to retrieve the old
state
- Use custom drm_gem_fb_create()
It's often a better choice to express such differences via different data structures (i.e., different instances of drm_mode_config_funcs) but it's not a big deal either.
Please go ahaed and merge if no one objects. All patches: Acked-by: Thomas Zimmermann <[email protected]> Best regards Thomas
- Only check damage clips and sync DMA buffers if non-coherent
buffers are used
Cheers,
