I don't see the point in having the complication, until someone complains. In my defense, I will point to the optimistic mutex spinning equally having no configurable option. And since the idea is that you only hit this if you are abusing i915 (e.g. benchmarking, or you have a readback on the critical patch, or if we haven't implemented semaphores), I would rather fix those scenarios as they arrive rather than giving the user an option to break. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
