• GIC-400 controller virtual interrupt handling in VM and hypervisor
    Hi, I am new to ARM architecture and as of now exploring GIC Controller GIC-400 and using ARM Cortex a57. Sorry for asking very fundamental flow of interrupts handling GIC-Virtual extension Let assume...
  • Is it possible the direct device's interrupt assignment to the guest OS instead of being routed by the hypervisor to the guest OS?
    Hi everyone, I'm currently working with devices virtualization and I have noticed on my experiments that one of the most sources of overhead comes from the device's interrupts, even if the guest OS...
  • Completing the set!
    You might have come across some pieces I've written recently on the ARMv7 architecture. Navigating the Cortex Maze ARMv7-A - Power to the People ARMv6-M vs ARMv7-M - Unpacking the Microcontrollers I've...
  • Virtual Interrupts and usage in ARM V8
    Hi Experts, What is the practical usage of the ARM v8 virtual interrupts ? How it helps in the performance of functionality ?
  • Getting started on Cortex A5 interrupts
    I'm new to Cortex A5 and I'm trying to figure out how the interrupts work. From my understanding, the Cortex A5 starts in secure mode and I don't change it. Now I set up the "secure interrupt controller...
