This series improves crc-core <-> driver interface. This series adds following functionality in the crc-core - Now control node will print all the available sources if implemented by driver along with current source. - Setting of sorce will fail if provided source is not supported - cleanup of crtc_crc_open function first allocate memory before enabling CRC generation - Don't block open() call instead wait in crc read call. Following IGT will fail due to crc-core <-> driver interface change igt@kms_pipe_crc_basic@bad-source <now setting bad-source itself will fail> ig@kms_pipe_crc_basic@nonblocking-crc-pipe-X ig@kms_pipe_crc_basic@nonblocking-crc-pipe-X-frame-sequence In nonblocking crc tests we'll get lesser crc's due to skipping crc AMD/Rockchip/rcar code path is not validated and need inputs Changes: - Add dri-devel in Cc Changes rev2: - now get_crc_sources returns a constant pointer to an array of source list and crc-core does the verification Changes rev3: - reorg patches to push non r-b patches to the last - add r-b tag Cc: dri-devel@xxxxxxxxxxxxxxxxxxxxx Mahesh Kumar (10): drm: crc: Introduce verify_crc_source callback drm: crc: Introduce get_crc_sources callback drm/rockchip/crc: Implement verify_crc_source callback drm/amdgpu_dm/crc: Implement verify_crc_source callback drm/rcar-du/crc: Implement verify_crc_source callback drm/i915/crc: implement verify_crc_source callback drm/i915/crc: implement get_crc_sources callback drm/crc: Cleanup crtc_crc_open function Revert "drm: crc: Wait for a frame before returning from open()" drm: crc: Introduce pre_crc_read function drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 1 + drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h | 7 +- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_crc.c | 20 +++- drivers/gpu/drm/drm_debugfs_crc.c | 79 ++++++++------ drivers/gpu/drm/i915/intel_display.c | 2 + drivers/gpu/drm/i915/intel_drv.h | 9 +- drivers/gpu/drm/i915/intel_pipe_crc.c | 119 ++++++++++++++++++++- drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 45 +++++++- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 26 ++++- include/drm/drm_crtc.h | 48 ++++++++- 10 files changed, 305 insertions(+), 51 deletions(-) -- 2.16.2 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
