HIDING LOGICAL PROCESSORS FROM AN OPERATING SYSTEM ON A COMPUTER

摘要

Hiding logical processors from an operating system (OS) of a computer is described. In an example, a method of hiding at least one logical processor in a computer having a plurality of logical processors includes: initializing the plurality of logical processors by executing a pre-boot routine in system firmware; identifying at least one logical processor of the plurality of logical processors to be hidden from an operating system (OS) of the computer to provide at least one hidden logical processor and at least one visible logical processor; placing each of the at least one hidden logical processor into a system management mode (SMM) by executing a park routine in the system firmware; and booting the OS of the computer to use the at least one visible logical processor.
