From 66030cc1c533e26bb4dbe8a356090f24dd734801 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Fri, 14 Feb 2025 12:59:40 -0600 Subject: [PATCH] cpufreq/amd-pstate-ut: Allow lowest nonlinear and lowest to be the same Several Ryzen AI processors support the exact same value for lowest nonlinear perf and lowest perf. Loosen up the unit tests to allow this scenario. Reviewed-by: Gautham R.
