◆ ConfigTDPLevels

UINT32 MSR_IVY_BRIDGE_PLATFORM_INFO_REGISTER::ConfigTDPLevels

[Bits 34:33] Package. Number of ConfigTDP Levels (R/O) 00: Only Base TDP level available. 01: One additional TDP level available. 02: Two additional TDP level available. 11: Reserved.

Definition at line 102 of file IvyBridgeMsr.h.

◆ LowPowerModeSupport

UINT32 MSR_IVY_BRIDGE_PLATFORM_INFO_REGISTER::LowPowerModeSupport

[Bit 32] Package. Low Power Mode Support (LPM) (R/O) When set to 1, indicates that LPM is supported, and when set to 0, indicates LPM is not supported.

Definition at line 96 of file IvyBridgeMsr.h.

◆ MaximumEfficiencyRatio

UINT32 MSR_IVY_BRIDGE_PLATFORM_INFO_REGISTER::MaximumEfficiencyRatio

[Bits 47:40] Package. Maximum Efficiency Ratio (R/O) The is the minimum ratio (maximum efficiency) that the processor can operates, in units of 100MHz.

Definition at line 109 of file IvyBridgeMsr.h.

◆ MaximumNonTurboRatio

UINT32 MSR_IVY_BRIDGE_PLATFORM_INFO_REGISTER::MaximumNonTurboRatio

[Bits 15:8] Package. Maximum Non-Turbo Ratio (R/O) The is the ratio of the frequency that invariant TSC runs at. Frequency = ratio * 100 MHz.

Definition at line 74 of file IvyBridgeMsr.h.

◆ MinimumOperatingRatio

UINT32 MSR_IVY_BRIDGE_PLATFORM_INFO_REGISTER::MinimumOperatingRatio

[Bits 55:48] Package. Minimum Operating Ratio (R/O) Contains the minimum supported operating ratio in units of 100 MHz.
