Right, so the real question is: "Is that ok to not get the spread rate (maximum of how much we derive from the requested frequency) into account?" I believe it is, on average the frequency is what we set-up. Maybe Adam can shed more light on why he thought it was necessary? As a side note, the spec does not mention that at all. -- Damien _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
