* Interrupts

* writes interrupt vectors into and the host reads vectors out of.
* There is a rptr (read pointer) that determines where the
* host is currently reading, and a wptr (write pointer)
* which determines where the GPU has written. When the
* pointers are equal, the ring is idle. When the GPU
* writes vectors to the ring buffer, it increments the
* wptr. When there is an interrupt, the host then starts
* fetching commands and processing them until the pointers are
* equal again at which point it updates the rptr.
