This series is a collection of -contributions from Joshua, Harry, and me to enhance the AMD KMS color -pipeline for Steam Deck/SteamOS by exposing additional pre-blending and -post-blending color capabilities from those available in the current DRM -KMS API[3]. - -The userspace case here is Gamescope which is the compositor for -SteamOS. Gamescope is already using these features to implement its -color management pipeline [4]. - -In this version, I try to address all concerns shared in the previous -one, i.e.: -- Replace DRM_ by AMDGPU_ prefix for transfer function enumeration; -- Explicitly define EOTFs and inverse EOTFs and set props accordingly; -- Document pre-defined transfer functions; -- Remove misleading comments; -- Remove post-blending/MPC shaper and 3D LUT support; -- Move driver-specific property operations from amdgpu_display.c to - amdgpu_dm_color.c; -- Reset planes if any color props change; -- Nits/small fixes; - -Bearing in mind the complexity of color concepts, I believe there is a -high chance of some misunderstanding from my side when defining EOTFs -and documenting pre-defined TFs. So, reviews are very important and -welcome (thanks in advance). FWIW, I added Harry as a co-developer of -this TF documentation since I based on his description of EOTF/inv_EOTF -and previous documentation work [5]. Let me know if there is a better -way for credits. - -Two DC patches were already applied and, therefore, removed from the -series. I added r-b according to previous feedback. We also add plane -CTM to driver-specific properties. As a result, this is the updated list -of all driver-specific color properties exposed by this series: - -- plane degamma LUT and pre-defined TF; -- plane HDR multiplier; -- plane CTM 3x4; -- plane shaper LUT and pre-defined TF; -- plane 3D LUT; -- plane blend LUT and pre-defined TF; -- CRTC gamma pre-defined TF; - -Remember you can find the AMD HW color capabilities documented here: -https://dri.freedesktop.org/docs/drm/gpu/amdgpu/display/display-manager.html#color-management-properties - -Worth mentioning that the pre-blending degamma block can use ROM curves -for some pre-defined TFs, but the other blocks use the AMD color module -to calculate this curve considering pre-defined coefficients. - -We need changes on DC gamut remap matrix to support the plane and CRTC -CTM on drivers that support both. I've sent a previous patch to apply -these changes to all DCN3+ families [6]. Here I use the same changes but -limited to DCN301. Just let me know if you prefer the previous/expanded -version. - -Finally, this is the Linux/AMD color management API before and after -blending with the driver-specific properties: - -+----------------------+ -| PLANE | -| | -| +----------------+ | -| | AMD Degamma | | -| | | | -| | EOTF | 1D LUT | | -| +--------+-------+ | -| | | -| +--------v-------+ | -| | AMD HDR | | -| | Multiply | | -| +--------+-------+ | -| | | -| +--------v-------+ | -| | AMD CTM (3x4) | | -| +--------+-------+ | -| | | -| +--------v-------+ | -| | AMD Shaper | | -| | | | -| | inv_EOTF | | | -| | Custom 1D LUT | | -| +--------+-------+ | -| | | -| +--------v-------+ | -| | AMD 3D LUT | | -| | 17^3/12-bit | | -| +--------+-------+ | -| | | -| +--------v-------+ | -| | AMD Blend | | -| | | | -| | EOTF | 1D LUT | | -| +--------+-------+ | -| | | -++----------v---------++ -|| Blending || -++----------+---------++ -| CRTC | | -| | | -| +-------v-------+ | -| | DRM Degamma | | -| | | | -| | Custom 1D LUT | | -| +-------+-------+ | -| | | -| +-------v-------+ | -| | DRM CTM (3x3) | | -| +-------+-------+ | -| | | -| +-------v-------+ | -| | DRM Gamma | | -| | | | -| | Custom 1D LUT | | -| +---------------+ | -| | *AMD Gamma | | -| | inv_EOTF | | -| +---------------+ | -| | -+----------------------+ -
