Because in the brave new world, that function doesn't work and is removed in the next? (next but one?) patch. I haven't thought of a good replacement yet. It would be nice to be able to categorically state when the GPU has the kernel context bound, but the closest I have atm is to be able to only say that when idle we are in the kernel context (and long may we remain idle!). -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
