PerfAutonomousMode

  • Article

PerfAutonomousMode controls whether autonomous mode is enabled on systems that implement version 2 of the CPPC interface, and determines whether desired performance requests should be provided to the platform. On systems with other performance state interfaces, this setting has no effect.

Note   Platforms that support CPPC version 2 may only support autonomous disabled or autonomous enabled mode. If only one mode is supported, the OS uses that mode and ignores the PerfAutonomousMode power setting.
