Field	Type	Description
`name`	string	Name of the config document. It is used to tell apart several scaling policies, and is reported on the `CPUScalingSpec` resources the document produces.
`selector`	CPUScalingSelector	Selector to match the cpufreq policies to configure. If several documents match the same policy, the first one (in document order) wins.
`governor`	string	Scaling governor to set, e.g. `performance`, `powersave` or `schedutil`. The governors a machine offers depend on its cpufreq driver, and are reported per policy in `availableGovernors` of the `CPUScalingStatus` resource.
`energyPerformancePreference`	string	Energy performance preference to set, e.g. `performance`, `balance_performance`, `balance_power` or `power`. Only some drivers implement this (HWP-enabled `intel_pstate`, `amd-pstate` in active mode); the values a machine offers are reported per policy in `availableEPPs` of the `CPUScalingStatus` resource.
`minFrequencyKhz`	uint64	Lower bound of the frequency window the governor may use, in kHz. Left alone when not set.
`maxFrequencyKhz`	uint64	Upper bound of the frequency window the governor may use, in kHz. Left alone when not set.

selector

CPUScalingSelector selects the cpufreq policies to configure.

Field	Type	Description	Value(s)
`match`	Expression	The Common Expression Language (CEL) expression to match the cpufreq policy. The `cpu` variable is a cpufreq policy as reported by the `CPUScalingStatus` resource.
