The collorary to this is that DynamicStateUpperBound is programmed to an unsafe value and should be (0x7fff0000 | 1) for most of our hardware. The actual value to program requires information not easily reported by the kernel (just like the mappable aperture size). -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
