From 91a4cd4f3d8169d7398f9123683f64575927c682 Mon Sep 17 00:00:00 2001 From: Dirk Brandewie Date: Tue, 17 Dec 2013 09:42:07 -0800 Subject: [PATCH] intel_pstate: Remove periodic P state boost Remove the periodic P state boost. This code required for some corner case benchmark tests. The calculation of the required P state was incorrect/inaccurate and would not allow P state increase. This was fixed by a combination of commits: 2134ed4 cpufreq / intel_pstate: Change to scale off of max P-state d253d2a intel_pstate: Improve accuracy by not truncating until final result References: https://bugzilla.kernel.org/show_bug.cgi?id=64271 Reported-by: Doug Smythies Signed-off-by: Dirk Brandewie Signed-off-by: Rafael J.
