 436 * buffer follows and at the end we have a JUMP back to the start + 12 (skipping
 437 * the initial JUMP).
 438 *
 439 * This is the risc program of the first buffer to be queued if the active list
 440 * is empty and it just keeps DMAing this buffer without generating any
 441 * interrupts.
 442 *
 443 * If a new buffer is added then the initial JUMP in the code for that buffer
 444 * will generate an interrupt which signals that the previous buffer has been
 445 * DMAed successfully and that it can be returned to userspace.
 446 *
 447 * It also sets the final jump of the previous buffer to the start of the new
 448 * buffer, thus chaining the new buffer into the DMA chain. This is a single
 449 * atomic u32 write, so there is no race condition.
 450 *
 451 * The end-result of all this that you only get an interrupt when a buffer
