Hello,
Here's the third version of the GEM CMA DMA-BUF support patches. Changes
compared to the previous version are minimal, there will hopefully not be any
need for a v4.
The code is based on the Exynos DRM DMA-BUF implementation. The exporter role
has been successfully tested with the Renesas R-Car DU driver.
Rob, could you please ack 5/5 ? Dave, could we then get the patches in v3.11 ?
Changes since v2:
- Removed #if CONFIG_DMA_SHARED_BUFFER
- Picked up Reviewed-by and Acked-by tags from the mailing list
Changes since v1:
- Added a mixing sg_free_table() in drm_gem_cma_dmabuf_map()
- Implement drm_gem_cma_dmabuf_mmap()
Laurent Pinchart (5):
drm/gem: Split drm_gem_mmap() into object search and object mapping
drm/omap: Use drm_gem_mmap_obj() to implement dma-buf mmap
drm: GEM CMA: Split object creation into object alloc and DMA memory
alloc
drm: GEM CMA: Split object mapping into GEM mapping and CMA mapping
drm: GEM CMA: Add DRM PRIME support
