◆ C_StateLimit

UINT32 MSR_SKYLAKE_PKG_CST_CONFIG_CONTROL_REGISTER::C_StateLimit

[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 Cstate limit. The following C-state code name encodings are supported: 000b: C0/C1 (no package C-state support) 001b: C2 010b: C6 (non-retention) 011b: C6 (retention) 111b: No Package C state limits. All C states supported by the processor are available.
