This series adds standard KMS static HDR metadata and BT.2020 RGB signalling to MSM DP and eDP, with HDR10 as the intended use case. It uses HDR_OUTPUT_METADATA, Colorspace and max bpc. Userspace supplies the HDR pixel content; DSC, dynamic HDR and tone mapping are outside this series.
Patch 1 allows max bpc registration before connector state allocation and initializes the corresponding state defaults. Patch 2 prepares generic SDP slots. Patches 3-5 establish PHY power ownership, serialize HPD state updates and add complete stream enable rollback, including AUX recovery for a connected external peer. New error returns are introduced together with their cleanup paths. Patches 6-8 add deferred link-status notification, capability cache validity and stream reconstruction for modesets leaving eDP self refresh. Patches 9-10 add atomic output depth selection and BT.2020 RGB signalling. The BT.2020 patch includes its own PSR disable/restore handling. Patch 11 independently fixes the uninitialized debugfs connector pointer. Patch 12 serializes SDR video-test state changes with mode programming. Patch 13 adds complete static HDR support: metadata validation and packing, 10 bpc enforcement, Generic2 programming and teardown, stream restoration, PSR exclusion and arbitration with video-pattern tests. A test request arriving after atomic check cannot replace the checked HDR output depth. This series is tested on a Lenovo Yoga Slim 7x using x1e80100.
