Hmm, I can see it is the i915_spin_request() consuming the time, but I was hoping to get the callgraph so I could see where the call to i915_wait_request was originating from. Could you regenerate the perf report with -g (or maybe you need a slightly newer perf)? -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
