Enable Configurable TDP

Applies Configurable Processor Base Power (cTDP) initialization settings based
on non-cTDP or cTDP. Default is 1: Applies to cTDP?if 0 then applies non-
cTDP? If 0 then applies non-cTDP and BIOS will bypass cTDP initialization flow.
Configurable TDP Boot Mode

Configurable Processor Base Power (cTDP) Mode as Nominal/Level1/Level2/
Deactivate TDP selection. Deactivate option will set MSR to Nominal and MMIO
to Zero.
Configurable TDP Lock

Configurable Processor Base Power (cTDP) Mode Lock sets the Lock bits on
TURBO_ACTIVATION_RATIO and CONFIG_TDP_CONTROL. Note: When
CTDP Lock is enabled, Custom ConfigTDP Count will be forced to 1 and Cus-
tom ConfigTDP Boot Index will be forced to 0.
CTDP BIOS control

Enable Configurable Processor Base Power (cTDP) control via runtime ACPI
BIOS methods. This "BIOS only" feature does not require EC or driver support.
Power Limit 1

Power Limit1 in milliwatts. BIOS will round to the nearest 1/8W when program-
ming. 0=no custom override. For 12.50W, enter 12500. Overlocking SKU: Value
must be between Max and Min Power Limits (specified by PACKAGE_POW-
ER_SKU_MSR). Other SKUs: This value must be between Min Power Limit and
Processor Base Power (TDP) Limit.
Power Limit 2

Power Limit2 in milliwatts. BIOS will round to the nearest 1/8W when program-
ming. 0=no custom override. For 12.50W, enter 12500. The processor applies
control policies such that the package power does not exceed this limit.
