The hacky approach is a module parameter (i915.trace_load=1) that we parse in i915_init() and enable the trace points manually. I remember this being possible, once upon a time... I'll keep digging to see how we can do it today. The long term solution is to ask for a generic method to enable module tracepoints upon module load. -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
