- cpuinfo_cur_freq
Current frequency of the CPUs belonging to this policy as obtained from the hardware (in KHz).
从硬件获得的属于此策略的 CPU 的当前频率，单位为 kHz。
This is expected to be the frequency the hardware actually runs at. If that frequency cannot be determined, this attribute should not be present.
这将是硬件实际运行的频率。如果无法确定该频率，则该属性不应存在。
- cpuinfo_max_freq
Maximum possible operating frequency the CPUs belonging to this policy can run at (in kHz).
属于此策略的 CPU 可以运行的最高可能工作频率，单位为 kHz。
- cpuinfo_min_freq
Minimum possible operating frequency the CPUs belonging to this policy can run at (in kHz).
属于此策略的 CPU 可以运行的最低可能工作频率，单位为 kHz。
- scaling_available_frequencies
List of available frequencies, in kHz.
- scaling_max_freq
Maximum frequency the CPUs belonging to this policy are allowed to be running at (in kHz).
属于此策略的 CPU 允许运行的最高频率，单位为 kHz。
This attribute is read-write and writing a string representing an integer to it will cause a new limit to be set (it must not be lower than the value of the scaling_min_freq attribute).
此属性是可读写的，向其写入表示整数的字符串将设置新的上限 (不得低于 scaling_min_freq 属性的值)。
- scaling_min_freq
Minimum frequency the CPUs belonging to this policy are allowed to be running at (in kHz).
属于此策略的 CPU 允许运行的最低频率，单位为 kHz。
This attribute is read-write and writing a string representing a non-negative integer to it will cause a new limit to be set (it must not be higher than the value of the scaling_max_freq attribute).
此属性是可读写的，向其写入表示非负整数的字符串将设置新的下限 (不得高于 scaling_max_freq 属性的值)。
