SH-4A and newer interrupt blocks all support a special shadowed page with all non-masking registers obscured when mapped in to userspace. This is primarily for use by userspace device drivers that are using special priority levels.

All of the balancing and CPU wakeup decisions are taken care of automatically by hardware for distributed vectors.
