From a00ec3874e7d326ab2dffbed92faddf6a77a84e9 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 26 Mar 2020 20:24:35 +0100 Subject: [PATCH] cpufreq: intel_pstate: Select schedutil as the default governor Modify cpufreq Kconfig to select schedutil as the default governor if the intel_pstate driver has been selected and SMP support is enabled (because schedutil depends on SMP). Also select schedutil as well as the performance governor from the intel_pstate Kconfig section to ensure the equivalence of the passive and active mode governor configuration options.
