Systems and methods for reduced boot power consumption using early BIOS controlled CPU P-states to enhance power budgeting and allocation

摘要

Systems and methods for reduced boot power consumption using early BIOS controlled CPU power states to enhance power budgeting and allocation. An information handling system may include a server. The server may include a central processing unit (CPU), a memory, a non-volatile random-access memory (NVRAM) device, a performance state (P-state) limiting indicator stored in the NVRAM device, a P-state value stored in the NVRAM, and a basic input/output system (BIOS) stored in the memory. The BIOS may read a power state limiting indicator stored in the NVRAM device and when the power state limiting indicator indicates that power state limiting is enabled, read a power state value stored in the NVRAM, and program the power state of the CPU to the power state value to cause the CPU to limit power supplied to the CPU to the power state value.
