Subject: [PATCH 05/25] drm/i915/pmu: "Frequency" is reported as accumulated cycles
Date: Sun, 10 Nov 2019 18:57:46 +0000
Message-ID: <> (raw)
In-Reply-To: <>

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.
