From 4cca0457686e4ee1677d69469e4ddfd94d389a80 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Tue, 11 Apr 2017 00:29:44 +0100 Subject: [PATCH] cpupower: Fix turbo frequency reporting for pre-Sandy Bridge cores The switch that conditionally sets CPUPOWER_CAP_HAS_TURBO_RATIO and CPUPOWER_CAP_IS_SNB flags is missing a break, so all cores get both flags set and an assumed base clock of 100 MHz for turbo values.
