This is to support cached and cached-coherent memory types in vulkan.
v2: - added patches 2/3 to enable using dma_ops_bypass - changed DRM_MSM_GEM_SYNC_CACHE patch to use dma_sync_sg_for_device() and dma_sync_sg_for_cpu(), and renamed sync flags.
Not sure I did the right thing with for the dma_ops_bypass part, this is what I came up with reading the emails.
Jonathan Marek (5): drm/msm: add MSM_BO_CACHED_COHERENT dma-direct: add dma_direct_bypass() to force direct ops drm/msm: call dma_direct_bypass() drm/msm: add DRM_MSM_GEM_SYNC_CACHE for non-coherent cache maintenance drm/msm: bump up the uapi version
