6888 * There is a rptr (read pointer) that determines where the
6889 * host is currently reading, and a wptr (write pointer)
6890 * which determines where the GPU has written. When the

6894 * fetching commands and processing them until the pointers are
6895 * equal again at which point it updates the rptr.
