+====== Information ======
-  watch --interval '0.5' grep \'cpu MHz\' '/proc/cpuinfo'
+  * ''x86_energy_perf_policy'' as udev rule
+  * Alternative to ''tuned'', ''tlp'', etc
-  * Check
+===== Prerequisites =====
-  sudo x86_energy_perf_policy
+  * [[linux;distros;opensuse_tumbleweed_gnome|openSUSE Tumbleweed (GNOME)]]
-  * Max Performance
+  sudo zypper remove --clean-deps 'tuned'
-  sudo x86_energy_perf_policy --all 'performance' --turbo-enable '1' --force
+  sudo zypper addlock 'tuned'
-====== Scripts ======
+  sudo zypper install 'cpupower'
-  * [[linux:distros:fedora_workstation_gnome|Fedora Workstation]]
+===== Check =====
-===== TuneD =====
+  watch --interval '0.5' grep \'cpu MHz\' '/proc/cpuinfo'
-  * Automatic power-management like ''tlp''
+  sudo x86_energy_perf_policy
-  * Required to remove ''tuned'' so it doesn't override below udev rule
-  sudo dnf remove 'tuned'
