Another datum:
/*
* Also there is software busyness tracking available we do not
* need the timer for I915_SAMPLE_BUSY counter.
*
* Use RCS as proxy for all engines.
*/
else if (intel_engine_supports_stats(i915->engine[RCS]))
enable &= ~BIT(I915_SAMPLE_BUSY);
becomes a global check rather than a proxy.
