This series defines new formats and adds implementation to the i915 driver. Since posting v1 I have removed the pixel normalize property, as it's not needed for basic functionality. Also, I have been working on adding support to userspace, but we can't land any patches until drm_fourcc.h has been updated here. I have submitted a series to Mesa to make use of the RGBA ordered formats: https://patchwork.freedesktop.org/series/54759/ My igt branch is reworked to drop usage of pixel normalize and includes use of f16c intrinsics to speed up conversion: https://gitlab.freedesktop.org/strassek/igt-gpu-tools/commits/fp16 I also have a libdrm branch with fp16 coverage added to modetest: https://gitlab.freedesktop.org/strassek/drm/commits/fp16 To serve as a smoke test of the whole stack I have a modified version of kmscube: https://gitlab.freedesktop.org/strassek/kmscube/commits/fp16 Kevin Strasser (3): drm/fourcc: Add 64 bpp half float formats drm/i915: Refactor icl_is_hdr_plane drm/i915/icl: Implement half float formats drivers/gpu/drm/drm_fourcc.c | 4 ++ drivers/gpu/drm/i915/intel_atomic.c | 4 +- drivers/gpu/drm/i915/intel_display.c | 27 ++++++++++++- drivers/gpu/drm/i915/intel_drv.h | 7 ++-- drivers/gpu/drm/i915/intel_sprite.c | 73 +++++++++++++++++++++++++++++++----- include/uapi/drm/drm_fourcc.h | 11 ++++++ 6 files changed, 111 insertions(+), 15 deletions(-) -- 2.7.4 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
