| 511 | * By choosing the right bulk transfer size, we are guaranteed to always |
| 512 | * get a short read for the last read of each frame. Frame sizes are |
| 513 | * always a composite number (width * height, or a multiple) so if we |
| 514 | * choose a prime number, we are guaranteed that the last read of a |
| 515 | * frame will be short. |
| 516 | * |
| 517 | * But it isn't that easy: the 2.6 kernel requires a multiple of 4KB, |
| 518 | * otherwise EOVERFLOW "babbling" errors occur. I have not been able |
| 519 | * to figure out why. [PMiller] |
| 520 | * |
| 521 | * The constant (13 * 4096) is the largest "prime enough" number less than 64KB. |
| 522 | * |
| 523 | * It isn't enough to know the number of bytes per frame, in case we |
| 524 | * have data dropouts or buffer overruns (even though the FX2 double |
| 525 | * buffers, there are some pretty strict real time constraints for |
| 526 | * isochronous transfer for larger frame sizes). |
