If you are feeling like adding a sentence, I would add it to setup_execbuf_for_cmd_buffer() where you explain the conditions for NO_RELOC. Explaining the difference there (or a bit earlier?) for setting LUT and how it means you have to walk the reloc[] after completing the execobj[] earlier in the function. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
