ARM VM System Specification
The virtual hardware platform must provide a number of mandatory peripherals:
Serial console: The platform should provide a console, based on an emulated pl011, a virtio-console, or a Xen PV console.
An ARM Generic Interrupt Controller v2 (GICv2) [3] or newer. GICv2 limits the the number of virtual CPUs to 8 cores, newer GIC versions removes this limitation.
The ARM virtual timer and counter should be available to the VM as per the ARM Generic Timers specification in the ARM ARM [1].
I just noticed that this doesn't mandate that the platform provides an RTC. As I understand it, the UEFI spec mandates that there's an RTC (could somebody more familiar with UEFI than me confirm/deny that?) so we should probably put one here.
Pardon my ignorance, but what exactly disqualifies Generic Timer implementations from being used as Real Time Clocks?
Thanks, Christopher
