Field Documentation

struct { ... } MSR_NEHALEM_PMG_IO_CAPTURE_BASE_REGISTER::Bits

Individual bit fields

UINT32 MSR_NEHALEM_PMG_IO_CAPTURE_BASE_REGISTER::CStateRange

[Bits 18:16] C-state Range (R/W) Specifies the encoding value of the maximum C-State code name to be included when IO read to MWAIT redirection is enabled by MSR_PKG_CST_CONFIG_CONTROL[bit10]: 000b - C3 is the max C-State to include 001b - C6 is the max C-State to include 010b - C7 is the max C-State to include.

UINT32 MSR_NEHALEM_PMG_IO_CAPTURE_BASE_REGISTER::Lvl2Base

[Bits 15:0] LVL_2 Base Address (R/W) Specifies the base address visible to software for IO redirection. If IO MWAIT Redirection is enabled, reads to this address will be consumed by the power management logic and decoded to MWAIT instructions. When IO port address redirection is enabled, this is the IO port address reported to the OS/software.
