From 9734213ed413da5ac791a984c8cecf1612fe4888 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Wed, 15 Dec 2021 17:28:02 -0800 Subject: [PATCH] tools/power/x86/intel-speed-select: Update max frequency When BIOS disables turbo, the cpuinfo_max_freq will also be same as the power up base frequency. When SST-PP causes increase in base frequency the performance will be still limited to the old base frequency as the cpuinfo_max_freq will not be updated. In this case we need to update scaling_max frequency to the new base_frequency. This will result in setting updated max performance limit in the Pstate driver. So performance will not be limited to the old base frequency.
