Dear all,
To the best of my knowledge, ARM hardware virtualization extensions can force the system to trap to the hypervisor when certain events occur such as privileged cache ops, MMU ops, and other privileged operations. Also, one can configure IRQ and FIQ to be routed to the hypervisor.
Using the ARM extensions can I configure IRQ from certain devices to trap (say timer) while others to be handled in the directly in the guest. Please share your experience.
Best wishes.
