From 2819bfef6483c66c55064ca678f2630a1a09f3f9 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Mon, 26 Aug 2024 16:13:54 -0500 Subject: x86/amd: Move amd_get_highest_perf() out of amd-pstate amd_pstate_get_highest_perf() is a helper used to get the highest perf value on AMD systems. It's used in amd-pstate as part of preferred core handling, but applicable for acpi-cpufreq as well. Move it out to cppc handling code as amd_get_highest_perf().
