Or rather, I can see the differentiation you want for init, but I can't see why you want to export it (since it ignores the ppat controller) or why you need to have a reserved bit, since you can just elevate the refcount. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
