Field Documentation

struct { ... } MSR_SILVERMONT_PKG_CST_CONFIG_CONTROL_REGISTER::Bits

Individual bit fields

UINT32 MSR_SILVERMONT_PKG_CST_CONFIG_CONTROL_REGISTER::CFGLock

[Bit 15] CFG Lock (R/WO) When set, lock bits 15:0 of this register until next reset.

UINT32 MSR_SILVERMONT_PKG_CST_CONFIG_CONTROL_REGISTER::IO_MWAIT

[Bit 10] I/O MWAIT Redirection Enable (R/W) When set, will map IO_read instructions sent to IO register specified by MSR_PMG_IO_CAPTURE_BASE to MWAIT instructions.

UINT32 MSR_SILVERMONT_PKG_CST_CONFIG_CONTROL_REGISTER::Limit

[Bits 2:0] Package C-State Limit (R/W) Specifies the lowest processor-specific C-state code name (consuming the least power). for the package. The default is set as factory-configured package C-state limit. The following C-state code name encodings are supported: 000b: C0 (no package C-sate support) 001b: C1 (Behavior is the same as 000b) 100b: C4 110b: C6 111b: C7 (Silvermont only).
