Hello All, We have raised a new merge request, for the HDR implementation in Weston: https://gitlab.freedesktop.org/wayland/weston/merge_requests/124
This patch series is in continuation to the design we published here: https://lists.freedesktop.org/archives/wayland-devel/2019-January/039808.html We have added a basic and limited focus implementation of HDR video playback stack, some of the testing specs are: - HDR Format: P010 - Some of the videos tested: https://4kmedia.org/samsung-wonderland-two-hdr-uhd-4k-demo ; and others from the same site. - Display / Overlays HW: Icelake - Monitors: LG 32UD99-W / 27UK650-W This patch-set targets: - HDR framework in drm-backend, which will allow a single plane HDR playback using Icelake HW overlays. - HDR support in Weston's GL backend, which will allow GL based rendering for HDR playback as a fallback method for other Hardwares. The Wayland protocol for HDR/Color management is already being discussed at various forums and lists. Please note that, this patch-set contains a temporary implementation of HDR metadata and colorspace protocol, which is under tag do-not-merge, and is for the sake of completion of testing stack. We are using this as a placeholder for actual color management protocol. https://lists.freedesktop.org/archives/wayland-devel/2019-March/040264.html To give everyone some background of these parallel threads of work, in my team, we have divided the total HDR development work into 3 parts: - The HDR protocol development as a color management subset: (Driven by Ankit Nautiyal) - Adding HDR support in GL backend : (Driven by Harish Krupo) - Compositor and framework changes in DRM-backend : (Driven by me, Shashank Sharma) Please provide us the feedback on the implementation. Regards Shashank
