Subject: [PATCH] cpufreq/amd-pstate: Remove obsolete amd_dynamic_epp documentation
Date: Sat, 5 Sep 2026 03:07:06 +0200 [thread overview]
Message-ID: <20260905010706.57380-1-kmehltretter@gmail.com> (raw)
The amd_dynamic_epp command-line parameter was removed. Dynamic EPP
is now selected through the per-policy energy_performance_preference
attribute, which is already documented.
Fixes: 32692fcf61ed ("cpufreq/amd-pstate: Remove "amd_dynamic_epp" cmdline and "dynamic_epp" sysfs")
Assisted-by: LLM
