Couple of general comments about the LSPCON stuff. a) we need infoframe readout support b) we need to stop sending infoframes to DVI sinks c) we need to figure out how to disable the AVI infoframe once enabled (if it doesn't get automagically disabled when do a modeset), because otherwise when we switch displays from HDMI to DVI we will still send the infoframe to the DVI sink I think those should be fixed first before we add more infoframes to the mix. Also if we use the SDP stuff for the HDR infoframe we should just integrate it properly with the already existing DP HDR metadata stuff. And we need to add readout support for that. -- Ville Syrjälä Intel _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
