434 | /* |
435 | * The risc program for each buffer works as follows: it starts with a simple |
436 | * 'JUMP to addr + 12', which is effectively a NOP. Then the code to DMA the |
437 | * buffer follows and at the end we have a JUMP back to the start + 12 (skipping |
438 | * the initial JUMP). |
439 | * |
440 | * This is the risc program of the first buffer to be queued if the active list |
441 | * is empty and it just keeps DMAing this buffer without generating any |
442 | * interrupts. |
443 | * |
444 | * If a new buffer is added then the initial JUMP in the code for that buffer |
445 | * will generate an interrupt which signals that the previous buffer has been |
446 | * DMAed successfully and that it can be returned to userspace. |
447 | * |
448 | * It also sets the final jump of the previous buffer to the start of the new |
449 | * buffer, thus chaining the new buffer into the DMA chain. This is a single |
450 | * atomic u32 write, so there is no race condition. |
451 | * |
452 | * The end-result of all this that you only get an interrupt when a buffer |
453 | * is ready, so the control flow is very easy. |
