FWIW, this seems like a bad idea, since with multiple active CRTCs it would make it essentially random at which intervals the ioctl returns, and which CRTCs are in vertical blank when it does. So it would be useless for both timing and tearing prevention purposes, i.e. more or less completely useless. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
