Since we wake the GT up before executing a request, and go to sleep as soon as it is retired, the GT wake time not only represents how long the device is powered up, but also provides a summary, albeit an overestimate, of the device runtime (i.e. the rc0 time to compare against rc6 time). v2: s/busy/awake/ v3: software-gt-awake-time and I915_PMU_SOFTWARE_GT_AWAKE_TIME Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Reported-by: kernel test robot <oliver.sang@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201215154456.13954-1-chris@chris-wilson.co.uk
