To do this effectively we recommend new interfaces to drm_plane. The first patch gives a bit of background on HDR and why we propose these interfaces. This update is only changing the documentation, not the code. We feel that we are not close to anything resembling a consensus for the DRM/KMS API to support (multi-plane) HDR and would like to further the discussion on this. The most important bits in the RFC document are probably the sections on defining HW details and defining SW intentions. We are worried defining intricate HW details on the DRM/KMS level leads to a lot of complexity for compositors which can be avoided by rather defining SW intentions. I will be off for the entire month of August with little time to follow this thread but would like to get my updated thoughts out for discussion anyways. Shashank Sharma will help support this discussion. v3: * Only doc updates (patch 1) * Add sections on single-plane and multi-plane HDR * Describe approach to define HW details vs approach to define SW intentions * Link Jeremy Cline's excellent HDR summaries * Outline intention behind overly verbose doc * Describe FP16 use-case * Clean up links v2: * Moved RFC from cover letter to kernel doc (Daniel Vetter) * Created new color space property instead of abusing color_encoding property (Ville) * Elaborated on need for named transfer functions * Expanded on reason for SDR luminance definition * Dropped 'color' from transfer function naming * Added output_transfer_function on crtc Bhawanpreet Lakha (3): drm/color: Add transfer functions for HDR/SDR on drm_plane drm/color: Add sdr boost property drm/color: Add color space plane property Harry Wentland (3): drm/doc: Color Management and HDR10 RFC drm/color: Add output transfer function to crtc drm/amd/display: reformat YCbCr-RGB conversion matrix Documentation/gpu/rfc/color_intentions.drawio | 1 + Documentation/gpu/rfc/color_intentions.svg | 3 + Documentation/gpu/rfc/colorpipe | 1 + Documentation/gpu/rfc/colorpipe.svg | 3 + Documentation/gpu/rfc/hdr-wide-gamut.rst | 580 ++++++++++++++++++ Documentation/gpu/rfc/index.rst | 1 + .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 17 +- drivers/gpu/drm/amd/display/dc/inc/hw/dpp.h | 28 +- .../gpu/drm/arm/display/komeda/komeda_crtc.c | 7 +- .../gpu/drm/arm/display/komeda/komeda_plane.c | 6 +- drivers/gpu/drm/arm/malidp_crtc.c | 7 +- drivers/gpu/drm/arm/malidp_planes.c | 6 +- drivers/gpu/drm/armada/armada_crtc.c | 5 +- drivers/gpu/drm/armada/armada_overlay.c | 6 +- .../gpu/drm/atmel-hlcdc/atmel_hlcdc_crtc.c | 7 +- drivers/gpu/drm/drm_atomic_uapi.c | 8 + drivers/gpu/drm/drm_color_mgmt.c | 177 +++++- drivers/gpu/drm/i915/display/intel_color.c | 11 +- drivers/gpu/drm/i915/display/intel_color.h | 2 +- drivers/gpu/drm/i915/display/intel_crtc.c | 4 +- drivers/gpu/drm/i915/display/intel_sprite.c | 6 +- .../drm/i915/display/skl_universal_plane.c | 6 +- drivers/gpu/drm/ingenic/ingenic-drm-drv.c | 9 +- drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 8 +- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 9 +- drivers/gpu/drm/nouveau/dispnv04/overlay.c | 6 +- drivers/gpu/drm/nouveau/dispnv50/head.c | 13 +- drivers/gpu/drm/omapdrm/omap_crtc.c | 10 +- drivers/gpu/drm/omapdrm/omap_plane.c | 6 +- drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 7 +- drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 5 +- drivers/gpu/drm/stm/ltdc.c | 8 +- drivers/gpu/drm/sun4i/sun8i_vi_layer.c | 10 +- drivers/gpu/drm/tidss/tidss_crtc.c | 9 +- drivers/gpu/drm/tidss/tidss_plane.c | 10 +- drivers/gpu/drm/vc4/vc4_crtc.c | 16 +- include/drm/drm_color_mgmt.h | 49 +- include/drm/drm_crtc.h | 20 + include/drm/drm_plane.h | 47 +- 39 files changed, 1074 insertions(+), 60 deletions(-) create mode 100644 Documentation/gpu/rfc/color_intentions.drawio create mode 100644 Documentation/gpu/rfc/color_intentions.svg create mode 100644 Documentation/gpu/rfc/colorpipe create mode 100644 Documentation/gpu/rfc/colorpipe.svg create mode 100644 Documentation/gpu/rfc/hdr-wide-gamut.rst -- 2.32.0
