From bad1135b3c27b62436d1f7c1e2463a0c1d60cba9 Mon Sep 17 00:00:00 2001 From: David Hunt Date: Wed, 12 May 2021 17:32:52 +0100 Subject: [PATCH] test/power: add turbo mode to frequency check [ upstream commit 6db92b3b9bb130acf0bc9d774ab2d75ea67d00df ] With the intel_pstate driver and turbo enabled, the top frequency in the frequency array is the P1+1, i.e. 2300001, whereas the frequency shown in scaling_cur_freq could be a lot higher. This patch adds a flag to the check_cur_freq function so that we can specify if a frequency is greater than expected (turbo mode), in which case the check should be successful.
