Should it be moved into bridge/ ? It isn't implemented as a DRM bridge driver at present, so this seems illogical. Is the longer term plan to convert it to be a DRM bridge? Secondly, if you want HDMI audio support, you may find the patches I maintain for the SolidRun devices useful, which add this as a standard ALSA device. I also have CEC support for it as well. If you're interested, I'll email those. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
