That's great!

The good news is that the synchronization instruction like Test and Set
(ldstub) should already be implemented (to be verified).

I think most of the work will be in the IRQMP to handle CPU start, CPU
status, IRQ broadcasting...

I'm not familiar with CPU start/stop but I'm sure you will find examples
in the code.

Don't hesitate to ask questions.
