Ok, bikeshedding time! We already use topology in conjunction with DP-MST, so at a toplevel this would be confusing. I would start with a gt/ dir for all of this info. Is this subslicing only for the render unit; are all platforms going to have the same fusing across all units? At the least, I thought we would be able to configure the powergating of the different slices on the different units. It seems a logical extension that fusing would be similar. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
