This patchset introduces AQUIRE_MEM packet submission at the begining of each gfx IB if requested by user mode client. This is helpful in solving issues with cache coherency during amdgpu_test and Vulkan CTS tests. Andrey Grodzovsky (4): drm/amdgpu: Add new ring callback to insert memory sync drm/amdgpu: Add AQUIRE_MEM PACKET3 fields defintion drm/amdgpu: Add mem_sync implementation for all the ASICs. drm/amdgpu: Add a UAPI flag for user to call mem_sync drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c | 3 ++ drivers/gpu/drm/amd/amdgpu/amdgpu_ib.c | 4 +++ drivers/gpu/drm/amd/amdgpu/amdgpu_job.h | 3 ++ drivers/gpu/drm/amd/amdgpu/amdgpu_ring.h | 1 + drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c | 27 +++++++++++++++++- drivers/gpu/drm/amd/amdgpu/gfx_v6_0.c | 16 ++++++++++- drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c | 16 ++++++++++- drivers/gpu/drm/amd/amdgpu/gfx_v8_0.c | 17 ++++++++++- drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c | 22 ++++++++++++++- drivers/gpu/drm/amd/amdgpu/nvd.h | 48 ++++++++++++++++++++++++++++++++ drivers/gpu/drm/amd/amdgpu/soc15d.h | 25 ++++++++++++++++- include/uapi/drm/amdgpu_drm.h | 2 ++ 12 files changed, 178 insertions(+), 6 deletions(-) -- 2.7.4 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
