Subject: [PATCH v2 07/17] cpufreq/amd-pstate-ut: Allow lowest nonlinear and lowest to be the same
Date: Fri, 14 Feb 2025 18:52:34 -0600 [thread overview]
Message-ID: <20250215005244.1212285-8-superm1@kernel.org> (raw)
In-Reply-To: <20250215005244.1212285-1-superm1@kernel.org>
From: Mario Limonciello <mario.limonciello@amd.com>
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.
