As Peter said, this is not a configuration we're willing to support: - we don't have a API to tell userspace emulation about interrupts generated by the generic timers - we could move the whole GIC emulation into the kernel (at the moment, only the distributor is there), but that would be a complete nightmare It really looks like a case of "let's drop a bunch of 64bit cores into an existing SoC".
