| 514 | * The FX2 chip does not give us a zero length read at end of frame. |
| 515 | * It does, however, give a short read at the end of a frame, if |
Daniel Mack | 3ad2f3f | 2010-02-03 08:01:28 +0800 | [diff] [blame] | 516 | * necessary, rather than run two frames together. |

| 518 | * By choosing the right bulk transfer size, we are guaranteed to always |
| 519 | * get a short read for the last read of each frame. Frame sizes are |
| 520 | * always a composite number (width * height, or a multiple) so if we |
| 521 | * choose a prime number, we are guaranteed that the last read of a |
| 522 | * frame will be short. |
| 523 | * |
| 524 | * But it isn't that easy: the 2.6 kernel requires a multiple of 4KB, |
| 525 | * otherwise EOVERFLOW "babbling" errors occur. I have not been able |
| 526 | * to figure out why. [PMiller] |
| 527 | * |
| 528 | * The constant (13 * 4096) is the largest "prime enough" number less than 64KB. |
| 529 | * |
| 530 | * It isn't enough to know the number of bytes per frame, in case we |
| 531 | * have data dropouts or buffer overruns (even though the FX2 double |
| 532 | * buffers, there are some pretty strict real time constraints for |
| 533 | * isochronous transfer for larger frame sizes). |
