Title (EN) HIDING LOGICAL PROCESSORS FROM AN OPERATING SYSTEM ON A COMPUTER
(FR) DISSIMULATION DE PROCESSEURS LOGIQUES AU SYSTÈME D'EXPLOITATION D'UN ORDINATEUR
Abstract:
(EN) 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.
(FR) L'invention concerne la dissimulation de processeurs logiques au système d'exploitation (OS) d'un ordinateur. Dans un exemple, un procédé pour masquer au moins un processeur logique d'un ordinateur possédant une pluralité de processeurs logiques consiste à : initialiser la pluralité de processeurs logiques en exécutant un programme de pré-amorçage dans le micrologiciel système; identifier au moins un processeur logique de la pluralité de processeurs logiques à dissimuler au système d'exploitation (OS) de l'ordinateur pour obtenir au moins un processeur logique caché et au moins un processeur logique visible; placer chacun desdits au moins un processeur logique caché dans un mode de gestion de système (SMM) en exécutant une routine de mise à l'arrêt dans le micrologiciel système; et amorcer l'OS de l'ordinateur pour utiliser ledit au moins un processeur logique visible.
