450  * will generate an interrupt which signals that the previous buffer has been
451  * DMAed successfully and that it can be returned to userspace.
452  *
453  * It also sets the final jump of the previous buffer to the start of the new
454  * buffer, thus chaining the new buffer into the DMA chain. This is a single
455  * atomic u32 write, so there is no race condition.
