Hello, Here's the second version of the GEM CMA DMA-BUF support patches. 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. Dave, is there a chance this could make it to v3.11 ? Changes compared to 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 drivers/gpu/drm/drm_gem.c | 83 +++--- drivers/gpu/drm/drm_gem_cma_helper.c | 408 +++++++++++++++++++++++++++--- drivers/gpu/drm/omapdrm/omap_gem_dmabuf.c | 32 +-- include/drm/drmP.h | 2 + include/drm/drm_gem_cma_helper.h | 9 + 5 files changed, 438 insertions(+), 96 deletions(-) -- Regards, Laurent Pinchart _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
