The driver provides minimum and maximum frequency limits and callbacks to set a policy. The policy in cpufreq sysfs is referred to as the "scaling governor". The cpufreq core can request the driver to operate in any of the two policies: -"performance: and "powersave". The driver decides which frequency to use based +"performance" and "powersave". The driver decides which frequency to use based on the above policy selection considering minimum and maximum frequency limits. The Intel P-State driver falls under the latter category, which implements the diff --git a/Documentation/kernel-parameters.txt b/Documentation/kernel-parameters.txt index 5b47acb86111..def479154d59 100644 --- a/Documentation/kernel-parameters.txt +++ b/Documentation/kernel-parameters.txt @@ -193,6 +193,12 @@ bytes respectively.
