Intel(R) TCC Mode Affected Settings
Item | Options | Description |
---|---|---|
Enable Monitor MWAIT | ASCII string | Allows Monitor and MWAIT instructions. |
CPU P-state Control | ASCII string | You can select to controls CPU P-states (performance states). [None]: Disables all P-states and processors work either at rated frequency or in Turbo Mode (if Turbo Mode is enabled). [Legacy]: CPU P-states will be presented to the OS. The OS power management (OSPM) controls which P-state is selected. [Autonomous]: The P-states are fully controlled by system hardware. No P-state support is required in the OS or VM. [Cooperative] is a combination of [Legacy] and [Autonomous]. The P-states are still controlled by hardware but the OS can provide hints to the hardware for P-state limits, indicating the desired setting. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. To change the settings, choose System Settings > Operating Modes > Choose Operating Mode > Custom Mode. |
Hardware P-states | ASCII string | [Disable]: Hardware chooses a P-state based on OS Request (Legacy P-States)\n [Native Mode]: Hardware chooses a P-state based on OS guidance\n [Out of Band Mode]: Hardware autonomously chooses a P-state (no OS guidance) |
