哪个软件包包含 Fedora 25 或 28 或 Qubes 操作系统上的“cpupower”实用程序/命令？

我需要该cpupower命令，只是为了看看它是否在 Qubes OS 4.0 中运行，其 dom0 运行 Fedora 25，其 VM 运行 Fedora 28（以及其他版本，具体取决于您安装的 TemplateVM）。

我尝试过（无济于事）：

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 OS）中，提供命令的包名称cpupower是kernel-tools

例子：

在 Qubes OS 4.0 的 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
  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: no
    Active: no

也许这不是 Qubes OS 中的方式......
