It's not enough though, e.g. the kernel itself was also using the wrong NOP packets. I think it would be better if the radeon winsys refused to initialize on Hawaii if RADEON_INFO_ACCEL_WORKING2 doesn't return 2, just like the Xorg driver. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
