LIMITING A NUMBER OF ILLEGITIMATE INTERRUPTS FROM SWITCHING A CENTRAL PROCESSING UNIT TO A SYSTEM MANAGEMENT MODE
Disclosed herein is a system for limiting the rate at which system management interrupts can suspend normal execution of a central processing unit (CPU) by switching the operating mode of the CPU from one of the real mode or the protected mode to the system management mode. The rate limits imposed b...

| description | Disclosed herein is a system for limiting the rate at which system management interrupts can suspend normal execution of a central processing unit (CPU) by switching the operating mode of the CPU from one of the real mode or the protected mode to the system management mode. The rate limits imposed by the system provides a protective layer against cyberattacks (e.g., a distributed denial-of-service (DDoS) attack) from malicious actors and ensures the CPU can be more efficient regarding the execution of workloads (e.g., processing threads).
Est divulgué un système permettant de limiter le débit auquel les interruptions de gestion du système peuvent suspendre l'exécution normale d'une unité centrale de traitement (CPU) en commutant le mode de fonctionnement de la CPU du mode réel ou du mode protégé vers le mode de gestion du système. Les limites de débit imposées par le système fournissent une couche de protection contre les cyberattaques (par exemple, une attaque par déni de service distribué (DDoS)) d'acteurs malveillants et garantissent une meilleure efficacité de la CPU concernant l'exécution des charges de travail (par exemple, des fils de traitement). |
