Used a new acronym today - HHI standing for hardware based hardware
interrupt. An interrupt thats runs a hardware process instead of an
interrupt subroutine.
The Qupls co-processor has an interrupt tied to the graphics command
queue being non-empty. It then triggers graphics operations instead of
running an ISR.
