Hello, this series is based on the RFC sent by Melssa Wen: "[RFC PATCH v2 00/18] Add DRM CRTC 3D LUT interface" https://lore.kernel.org/dri-devel/20230109143846.1966301-1-mwen@xxxxxxxxxx/ that introduces CRTC properties to control 3D LUT operations. The R-Car DU peripheral has a post-blending color management pipeline (CMM) composed by (in order of processing) a 3D LUT a 1D LUT and a Color conversion unit. The CMM driver already supported operating the 1D LUT, this series add support for the cubic LUT (named CLU). I've been made aware by Melissa and Pekka that the focus of upstream for color management properties is now on the definition of the "Plane color pipeline" properties https://lore.kernel.org/dri-devel/QMers3awXvNCQlyhWdTtsPwkp5ie9bze_hD5nAccFW7a_RXlWjYB7MoUW_8CKLT2bSQwIXVi5H6VULYIxCdgvryZoAoJnC5lZgyK1QWn488=@emersion.fr/ Unfortunately the model there proposed doesn't match the R-Car DU hardware which has color management at the post-blending level and not per plane (I've cc-ed all the receivers of that series, just in case). The user-space interface has been validated with dedicated unit tests for the R-Car DU test suite (kms-test) which are available at: https://git.sr.ht/~jmondi_/kms-test The series validates the usage of the HW interface in the hope of re-starting discussions and interests in the definition of CRTC color management properties.
