在Fedora 25或28或Qubes OS中，哪个包包含"cpupower“实用程序/命令？

Question

我需要cpupower命令，如果只查看它在QubesOS4.0中是否有效，它的dom0运行Fedora 25，其VM运行Fedora 28(以及其他版本，取决于您安装的TemplateVMs )。

我试过(但没有结果)：

sudo qubes-dom0-update --action=search cpupower    
sudo qubes-dom0-update --action=search cpufreq
sudo qubes-dom0-update --action=search power
sudo qubes-dom0-update --action=search cpu

在Fedora (和Qubes )中，提供cpupower命令的包名是kernel-tools

示例：

在QubesOS4.0 's dom0中：

[ctor@dom0 ~]$ sudo qubes-dom0-update kernel-tools
...
Installed:
  kernel-tools.x86_64 4.13.16-100.fc25                         kernel-tools-libs.x86_64 4.13.16-100.fc25

[ctor@dom0 ~]$ sudo cpupower frequency-info
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
  CPUs which run at the same hardware frequency: Not Available
  CPUs which need to have their frequency coordinated by software: Not Available
  maximum transition latency:  Cannot determine or is not supported.
Not Available
  available cpufreq governors: Not Available
  Unable to determine current policy
  current CPU frequency: Unable to call hardware
  current CPU frequency:  Unable to call to kernel
  boost state support:
    Supported: yes
    Active: yes

在Fedora 28 VM (Qubes OS 4.0)中：

[user@dev01-w-s-f-fdr28 ~]$ sudo dnf install kernel-tools
...
Installed:
  kernel-tools.x86_64 4.17.19-200.fc28                                          
  kernel-tools-libs.x86_64 4.17.19-200.fc28                                     

[user@dev01-w-s-f-fdr28 ~]$ sudo cpupower frequency-info
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
  CPUs which run at the same hardware frequency: Not Available
  CPUs which need to have their frequency coordinated by software: Not Available

也许这不是Qubes操作系统的方式..。如果您对纯Fedora感兴趣，请参见这答案(即。而不是Qubes )。
