FWIW, in my yet to be published new stereo 3D series, I added a DRM_SET_CAP ioctl for userspace to tell DRM to expose some stereo bits in the mode structure. Making it possible for the primary plane to be exposed as a drm_plane could be the second user of this ioctl (well, assuming people are fine with this new ioctl, a whole different story, but now that'd be 2 users of it). -- Damien _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
