It's a distinct step from emit_bb_start and should be using emit_bb_start itself to execute the batch. Use i915_vma_move_to_active to couple into retirement correctly, and use pin properly. If you feel emit_bb is doing too much, split it up into primitives rather than continue to overload it; emit_bb is used and will be used outside of execbuf. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
