 * Interrupts
 * Starting with r6xx, interrupts are handled via a ring buffer.
 * Ring buffers are areas of GPU accessible memory that the GPU
 * 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.
