From 366430b5c2f61a75d45b9fc00886ffff12f395ab Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sat, 24 Dec 2016 00:29:56 +0100 Subject: [PATCH] cpufreq: intel_pstate: Do not expose PID parameters in passive mode If intel_pstate works in the passive mode in which it acts as a regular cpufreq driver and collaborates with generic cpufreq governors, the PID parameters are not used, so do not expose them via debugfs in that case.
