We are looking to enable HDR support for a couple of single-plane and multi-plane scenarios. 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. 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/hdr-wide-gamut.rst | 416 ++++++++++++++++++ Documentation/gpu/rfc/index.rst | 4 + .../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 +- 35 files changed, 905 insertions(+), 60 deletions(-) create mode 100644 Documentation/gpu/rfc/hdr-wide-gamut.rst -- 2.31.1
