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 drivers/gpu/drm/drm_fb_cma_helper.c | 46 ++++++++++++++++++ drivers/gpu/drm/drm_gem_cma_helper.c | 38 +++++++++++---- drivers/gpu/drm/ingenic/ingenic-drm-drv.c | 59 +++++++++++++++++++++-- drivers/gpu/drm/ingenic/ingenic-drm.h | 1 + drivers/gpu/drm/ingenic/ingenic-ipu.c | 21 ++++++-- include/drm/drm_fb_cma_helper.h | 4 ++ include/drm/drm_gem_cma_helper.h | 3 ++ 7 files changed, 156 insertions(+), 16 deletions(-) Acked-by: Thomas Zimmermann
