I think we eventually need to be able to hot-plug connectors (and maybe encoders) to support fancy dp1.2 output routing and multiple streams over the same cable. But I agree that hotplugging crtcs is insane and better done by hotplugging an entire drm device with that crtc. In any case not something to worry about right now. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
