MIN_SPACE_FOR_ADD_REQUEST already has to and does take this into account. We either make it variable and universally compute it per-engine/per-gen or keep using the fixed constant that is large enough for everybody. This code should remain common to all paths until the duplication is removed. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
