(FR) ARCHITECTURE DE PRIVILÈGES DE MODE DE GESTION DE SYSTÈME
Abstract:
(EN) In one example, a system for a system management mode (SMM) privilege architecture includes a computing device comprising: a first portion of SMM instructions to set up a number of resources and implement a privilege architecture for the SMM of a computing device and a second portion of SMM instructions to execute a number of functions during the SMM of the computing device, wherein the privilege architecture assigns the first portion of SMM instructions to a first privilege level and assigns the second portion of SMM instructions to a second privilege level.
(FR) Un exemple de l'invention concerne un système pour une architecture de privilèges de mode de gestion de système (SMM) incluant un dispositif informatique comprenant : une première portion d'instructions SMM destinée à configurer un certain nombre de ressources et à mettre en œuvre une architecture de privilèges pour le SMM d'un dispositif informatique et une deuxième portion d'instructions SMM destinée à exécuter un certain nombre de fonctions pendant le SMM du dispositif informatique. L'architecture de privilèges attribue la première portion d'instructions SMM à un premier niveau de privilège et attribue la deuxième portion d'instructions SMM à un deuxième niveau de privilège.
