It is a collection of contributions from Joshua, Harry and I to enhance AMD KMS color pipeline for Steam Deck/SteamOS by exposing the large set of color caps available in AMD display HW. Considering RFC feedback, this patchset differs from the previous one by removing the KConfig option and just guarding driver-specific properties with `AMD_PRIVATE_COLOR` - but we also removed the guards from internal elements and operations. We stopped to advertise CRTC shaper and 3D LUTs properties since they aren't in use in the Steam Deck color pipeline[2]. On the other hand, we keep mapping CRTC shaper and 3D LUTs (DM) to DC MPC setup. We also improved curve calculations to take into account HW color caps. In short, for pre-blending, we added the following properties: - plane degamma LUT and predefined transfer function; - plane HDR multiplier - plane shaper LUT/transfer function; - plane 3D LUT; and finally, - plane blend LUT/transfer function, just before blending. After blending, we already have DRM CRTC degamma/gamma LUTs and CTM, therefore, we extend post-blending color pipeline with CRTC gamma transfer function. The first three patches are on DRM KMS side. We expose DRM property helper for blob lookup and replacement so that we can use it for managing driver-specific properties. We add a tracked for plane color mgmt changes and increase the maximum number of properties to accommodate this expansion. The userspace case here is Gamescope which is the compositor for SteamOS. It's already using all of this functionality to implement its color management pipeline right now [3]. Current IGT tests kms_color and amdgpu/amd_color on DCN301 and DCN21 HW preserve the same results with and without the guard. Finally, I may have missed something, please let me know if that's the case.
