From e88866ef02851c88fe95a4bb97820b94b4d46f36 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Sat, 9 Nov 2019 10:53:56 +0000 Subject: [PATCH] drm/i915/pmu: "Frequency" is reported as accumulated cycles We report "frequencies" (actual-frequency, requested-frequency) as the number of accumulated cycles so that the average frequency over that period may be determined by the user. This means the units we report to the user are Mcycles (or just M), not MHz.
