| 490 | /* OLD (Original design by Roberto Deza): |
| 491 | ** This code will setup the SAA7146_RPS1 to generate a square |
| 492 | ** wave on GPIO3, changing when a field (TS_HEIGHT/2 "lines" of |
| 493 | ** TS_WIDTH packets) has been acquired on SAA7146_D1B video port; |
| 494 | ** then, this GPIO3 output which is connected to the D1B_VSYNC |
| 495 | ** input, will trigger the acquisition of the alternate field |
| 496 | ** and so on. |
| 497 | ** Currently, the TT_budget / WinTV_Nova cards have two ICs |
| 498 | ** (74HCT4040, LVC74) for the generation of this VSYNC signal, |
| 499 | ** which seems that can be done perfectly without this :-)). |
| 500 | */ |
| 501 | |
| 502 | /* New design (By Emard) |
| 503 | ** this rps1 code will copy internal HS event to GPIO3 pin. |
| 504 | ** GPIO3 is in budget-patch hardware connectd to port B VSYNC |
| 505 | |
| 506 | ** HS is an internal event of 7146, accessible with RPS |
| 507 | ** and temporarily raised high every n lines |
| 508 | ** (n in defined in the RPS_THRESH1 counter threshold) |
| 509 | ** I think HS is raised high on the beginning of the n-th line |
| 510 | ** and remains high until this n-th line that triggered |
| 511 | ** it is completely received. When the receiption of n-th line |
| 512 | ** ends, HS is lowered. |
| 513 | |
| 514 | ** To transmit data over DMA, 7146 needs changing state at |
| 515 | ** port B VSYNC pin. Any changing of port B VSYNC will |
| 516 | ** cause some DMA data transfer, with more or less packets loss. |
| 517 | ** It depends on the phase and frequency of VSYNC and |
| 518 | ** the way of 7146 is instructed to trigger on port B (defined |
| 519 | ** in DD1_INIT register, 3rd nibble from the right valid |
| 520 | ** numbers are 0-7, see datasheet) |
| 521 | ** |
| 522 | ** The correct triggering can minimize packet loss, |
| 523 | ** dvbtraffic should give this stable bandwidths: |
| 524 | ** 22k transponder = 33814 kbit/s |
| 525 | ** 27.5k transponder = 38045 kbit/s |
| 526 | ** by experiment it is found that the best results |
| 527 | ** (stable bandwidths and almost no packet loss) |
| 528 | ** are obtained using DD1_INIT triggering number 2 |
| 529 | ** (Va at rising edge of VS Fa = HS x VS-failing forced toggle) |
| 530 | ** and a VSYNC phase that occurs in the middle of DMA transfer |
| 531 | ** (about byte 188*512=96256 in the DMA window). |
| 532 | ** |
| 533 | ** Phase of HS is still not clear to me how to control, |
| 534 | ** It just happens to be so. It can be seen if one enables |
| 535 | ** RPS_IRQ and print Event Counter 1 in vpeirq(). Every |
| 536 | ** time RPS_INTERRUPT is called, the Event Counter 1 will |
| 537 | ** increment. That's how the 7146 is programmed to do event |
| 538 | ** counting in this budget-patch.c |
| 539 | ** I *think* HPS setting has something to do with the phase |
| 540 | ** of HS but I cant be 100% sure in that. |
| 541 | |
| 542 | ** hardware debug note: a working budget card (including budget patch) |
| 543 | ** with vpeirq() interrupt setup in mode "0x90" (every 64K) will |
| 544 | ** generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes |
| 545 | ** and that means 3*25=75 Hz of interrupt freqency, as seen by |
| 546 | ** watch cat /proc/interrupts |
| 547 | ** |
| 548 | ** If this frequency is 3x lower (and data received in the DMA |
| 549 | ** buffer don't start with 0x47, but in the middle of packets, |
| 550 | ** whose lengths appear to be like 188 292 188 104 etc. |
| 551 | ** this means VSYNC line is not connected in the hardware. |
| 552 | ** (check soldering pcb and pins) |
| 553 | ** The same behaviour of missing VSYNC can be duplicated on budget |
| 554 | ** cards, by seting DD1_INIT trigger mode 7 in 3rd nibble. |
