From fd604ae6c261c5a56bb977ae99f875bbd7264a3f Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Thu, 2 Jan 2025 08:12:04 -0600 Subject: [PATCH] cpufreq/amd-pstate: Fix prefcore rankings commit 50a062a76200 ("cpufreq/amd-pstate: Store the boost numerator as highest perf again") updated the value stored for highest perf to no longer store the highest perf value but instead the boost numerator. This is a fixed value for systems with preferred cores and not appropriate for use ITMT rankings. Update the value used for ITMT rankings to be the preferred core ranking.
