As a device-driver developer, I want vemu to model ARM local peripherals (per-core timer/mailbox/IPI), so that I can build and test firmware that needs SMP bring-up and per-core IRQs on Pi 2/3 long before the hardware is in hand.

Why it matters

SMP bring-up and per-core IRQs on Pi 2/3

Summary

BCM2836/2837 per-core local timer, mailboxes and inter-core interrupts

Scope of work

Not present today. Deliver a behavioral model of ARM local peripherals (per-core timer/mailbox/IPI). What it is: BCM2836/2837 per-core local timer, mailboxes and inter-core interrupts. Why it matters: SMP bring-up and per-core IRQs on Pi 2/3.

Current state

Status: Not implemented. Notes / evidence: Not present; required for multi-core Pi.
