I just want to get the governor, just like “ondemand” with no more information, to use its value in a program. Note that cpu* will give you the scaling governor of all your cores and not just e.g. cpu0.
How does the Governor affect the CPU performance?
The governor defines the power characteristics of the system CPU, which in turn affects CPU performance. Each governor has its own unique behavior, purpose, and suitability in terms of workload.
How to set Linux CPU scaling governor to Max performance?
For benchmarking, we usually want maximum performance and power. By default, most Linux distributions place the system into a ‘powersave’ mode. The definition for ‘powersave’ and ‘performance’ scaling governors are:
