Subject: [PATCH v2 20/21] cpupower: print amd-pstate information on cpupower
Date: Sun, 26 Sep 2021 17:06:04 +0800 [thread overview]
Message-ID: <20210926090605.3556134-21-ray.huang@amd.com> (raw)
In-Reply-To: <20210926090605.3556134-1-ray.huang@amd.com>
amd-pstate kernel module is using the fine grain frequency instead of
acpi hardware pstate. So the performance and frequency values should be
printed in frequency-info.
