 * Interrupts use a ring buffer on r6xx/r7xx hardware.  It works pretty
 * the same as the CP ring buffer, but in reverse.  Rather than the CPU
 * writing to the ring and the GPU consuming, the GPU writes to the ring
 * and host consumes.  As the host irq handler processes interrupts, it
 * increments the rptr.  When the rptr catches up with the wptr, all the
 * current interrupts have been processed.
