For the simple chain of [1, 3], does 1 being signaled imply that all points up to 3 are signaled, or does 3 not being signaled imply that all points after 1 are not. If that's mentioned already somewhere, my bad. If not, could you put the answer somewhere. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
