Emitting a batch is trivial: https://lists.freedesktop.org/archives/mesa-dev/2015-August/091077.html But we do want to share the bufmgr between screens, and you do want to deprecate the current intel_batchbuffer.c due to the very large overhead it imposes. -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
