我试过了:
cpupower frequency-set -g performance
但是,频率仍然只有 1200 MHz。
只有当我在机器上加载负载时它才会上升,但它应该始终以 100% 的 cpu 频率运行。
使用 SLES 12.2。

我错过了什么?
如果可能是某些 UEFI 设置,是否有任何命令,例如:asu64 无需重启即可更新 UEFI 设置?
机器是“x3850 X6”,CPU 是:“Xeon(R) CPU E7-8880 v4 @ 2.20GHz”。
更新#1:找到了一些东西,也许是:
SERVER:~ # systemctl start cpupower
Failed to start cpupower.service: Unit cpupower.service failed to load: No such file or directory.
SERVER:~ # echo $?
5
SERVER:~ #
SERVER:~ # systemctl status cpupower
? cpupower.service
Loaded: not-found (Reason: No such file or directory)

更新#1 的更新:我遵循了https://www.suse.com/support/kb/doc/?id=7021316但没有帮助。
更新#2:尝试设置频率但没有帮助。
SERVER:~ # lscpu | awk '/Model name:/{print $NF}'
2.20GHz
SERVER:~ # cpupower frequency-set -u 2.20GHz
...
SERVER:~ # cpupower frequency-set -u 2.2GHz
...
SERVER:~ # lscpu |egrep "CPU MHz|CPU(s)" | awk '{print $3}' | awk -F "." '{print $1}'
1200

我想这就是你要找的:
