From ee3b89786ce371963e159f9ff358430529909d28 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Mon, 14 Dec 2020 09:43:49 +0000 Subject: [PATCH] drm/i915/pmu: Remove !CONFIG_PM code Chris spotted that since 87f31b25636d ("drm/i915/pmu: Use GT parked for estimating RC6 while asleep") we don't rely on runtime pm internals when estimating RC6 while asleep. We can remove the ifdef code to simplify and at the same time wake up the device less when querying RC6 if CONFIG_PM is not compiled in.
