| |
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
Paul Cercueil (3): drm: Add support for GEM buffers backed by non-coherent memory drm: Add and export function drm_fb_cma_sync_non_coherent drm/ingenic: Add option to alloc cached GEM buffers
