From: Chris Wilson Date: Sat, 9 Nov 2019 10:53:56 +0000 (+0000) Subject: drm/i915/pmu: "Frequency" is reported as accumulated cycles X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e88866ef02851c88fe95a4bb97820b94b4d46f36;p=linux.git 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.
