From 8c3b1ba0e7ea9a80b0ee4b4445ea59c806787813 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 15 Dec 2020 15:44:56 +0000 Subject: drm/i915/gt: Track the overall awake/busy time 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 Reviewed-by: Tvrtko Ursulin Cc: Matthew Brost Reported-by: kernel test robot Link: https://patchwork.freedesktop.org/patch/msgid/20201215154456.13954-1-chris@chris-wilson.co.uk --- include/uapi/drm/i915_drm.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include') diff --git a/include/uapi/drm/i915_drm.h b/include/uapi/drm/i915_drm.h index 6edcb2b6c708..1987e2ea79a3 100644 --- a/include/uapi/drm/i915_drm.h +++ b/include/uapi/drm/i915_drm.h @@ -177,6 +177,7 @@ enum drm_i915_pmu_engine_sample { #define I915_PMU_REQUESTED_FREQUENCY __I915_PMU_OTHER(1) #define I915_PMU_INTERRUPTS __I915_PMU_OTHER(2) #define I915_PMU_RC6_RESIDENCY __I915_PMU_OTHER(3) +#define I915_PMU_SOFTWARE_GT_AWAKE_TIME __I915_PMU_OTHER(4) #define I915_PMU_LAST /* Deprecated - do not use */ I915_PMU_RC6_RESIDENCY -- cgit v1.2.3
