From 584ee3dcb1d6232857c1e38bb28d9f6bf0ec89f5 Mon Sep 17 00:00:00 2001 From: Alexandra Yates Date: Wed, 18 Nov 2015 14:58:40 -0800 Subject: intel_pstate: Fix "performance" mode behavior with HWP enabled If hardware-driven P-state selection (HWP) is enabled, the "performance" mode of intel_pstate should only allow the processor to use the highest-performance P-state available. That is not the case currently, so make it actually happen. Acked-by: Srinivas Pandruvada Signed-off-by: Alexandra Yates [ rjw: Subject and changelog ] Signed-off-by: Rafael J.
