Secure, Fast and Normal Virtual Interrupt Direct Assignment in a Virtualized Interrupt Controller in a Mobile System-On-Chip

摘要

Aspects include apparatuses and methods for secure, fast and normal virtual interrupt direct assignment managing secure and non-secure, virtual and physical interrupts by processor having a plurality of execution environments, including a trusted (secure) and a non-secure execution environment. An interrupt controller may identify a security group value for an interrupt and direct secure interrupts to the trusted execution environment. The interrupt controller may identify a direct assignment value for the non-secure interrupts indicating whether the non-secure interrupt is owned by a high level operating system (HLOS) Guest or a virtual machine manager (VMM), and whether it is a fast or a normal virtual interrupt. The interrupt controller may direct the HLOS Guest owned interrupt to the HLOS Guest while bypassing the VMM. When the HLOS Guest in unavailable, the interrupt may be directed to the VMM to attempt to pass the interrupt to the HLOS Guest until successful.
