Are these dynamically known counts? I think having a statically known max waves would be useful (and noting that it is maximum static known) in addition to the dynamic from the runtime number of inputs. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
