6890 * Interrupts

6893 * writes interrupt vectors into and the host reads vectors out of.
6894 * There is a rptr (read pointer) that determines where the
6895 * host is currently reading, and a wptr (write pointer)
6896 * which determines where the GPU has written. When the

6900 * fetching commands and processing them until the pointers are
6901 * equal again at which point it updates the rptr.
