| 502 | ** TS_WIDTH packets) has been acquired on SAA7146_D1B video port; |
| 503 | ** then, this GPIO3 output which is connected to the D1B_VSYNC |
| 504 | ** input, will trigger the acquisition of the alternate field |
| 505 | ** and so on. |
| 506 | ** Currently, the TT_budget / WinTV_Nova cards have two ICs |
| 507 | ** (74HCT4040, LVC74) for the generation of this VSYNC signal, |
| 508 | ** which seems that can be done perfectly without this :-)). |

| 515 | ** HS is an internal event of 7146, accessible with RPS |
| 516 | ** and temporarily raised high every n lines |
| 517 | ** (n in defined in the RPS_THRESH1 counter threshold) |
| 518 | ** I think HS is raised high on the beginning of the n-th line |
| 519 | ** and remains high until this n-th line that triggered |
Matt LaPlante | 0779bf2 | 2006-11-30 05:24:39 +0100 | [diff] [blame] | 520 | ** it is completely received. When the reception of n-th line |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 521 | ** ends, HS is lowered. |
| 522 | |
| 523 | ** To transmit data over DMA, 7146 needs changing state at |
| 524 | ** port B VSYNC pin. Any changing of port B VSYNC will |
| 525 | ** cause some DMA data transfer, with more or less packets loss. |
| 526 | ** It depends on the phase and frequency of VSYNC and |
| 527 | ** the way of 7146 is instructed to trigger on port B (defined |
| 528 | ** in DD1_INIT register, 3rd nibble from the right valid |
| 529 | ** numbers are 0-7, see datasheet) |
| 530 | ** |
| 531 | ** The correct triggering can minimize packet loss, |
| 532 | ** dvbtraffic should give this stable bandwidths: |
| 533 | ** 22k transponder = 33814 kbit/s |
| 534 | ** 27.5k transponder = 38045 kbit/s |
| 535 | ** by experiment it is found that the best results |
| 536 | ** (stable bandwidths and almost no packet loss) |
| 537 | ** are obtained using DD1_INIT triggering number 2 |
| 538 | ** (Va at rising edge of VS Fa = HS x VS-failing forced toggle) |
| 539 | ** and a VSYNC phase that occurs in the middle of DMA transfer |
| 540 | ** (about byte 188*512=96256 in the DMA window). |
| 541 | ** |
| 542 | ** Phase of HS is still not clear to me how to control, |
| 543 | ** It just happens to be so. It can be seen if one enables |
| 544 | ** RPS_IRQ and print Event Counter 1 in vpeirq(). Every |
| 545 | ** time RPS_INTERRUPT is called, the Event Counter 1 will |
| 546 | ** increment. That's how the 7146 is programmed to do event |
