1475 * This is the risc program of the first buffer to be queued if the active list

1479 * If a new buffer is added then the initial JUMP in the code for that buffer
1480 * will generate an interrupt which signals that the previous buffer has been
1481 * DMAed successfully and that it can be returned to userspace.
1483 * It also sets the final jump of the previous buffer to the start of the new
1484 * buffer, thus chaining the new buffer into the DMA chain. This is a single
1485 * atomic u32 write, so there is no race condition.
1487 * The end-result of all this that you only get an interrupt when a buffer
1488 * is ready, so the control flow is very easy.
