From e42e4d9ee2e953137488e531be82c4d2d1c10d1c Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 26 Feb 2025 01:49:23 -0600 Subject: 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.
