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 547** counting in this budget-patch.c 548** I *think* HPS setting has something to do with the phase 549** of HS but I can't be 100% sure in that. 550 551** hardware debug note: a working budget card (including budget patch) 552** with vpeirq() interrupt setup in mode "0x90" (every 64K) will 553** generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes 554** and that means 3*25=75 Hz of interrupt frequency, as seen by 555** watch cat /proc/interrupts 556** 557** If this frequency is 3x lower (and data received in the DMA 558** buffer don't start with 0x47, but in the middle of packets, 559** whose lengths appear to be like 188 292 188 104 etc. 560** this means VSYNC line is not connected in the hardware. 561** (check soldering pcb and pins) 562** The same behaviour of missing VSYNC can be duplicated on budget 563** cards, by setting DD1_INIT trigger mode 7 in 3rd nibble. 564*/ 565 566 // Setup RPS1 "program" (p35) 567 count = 0; 568 569 570 // Wait Source Line Counter Threshold (p36) 571 WRITE_RPS1(CMD_PAUSE | EVT_HS); 572 // Set GPIO3=1 (p42) 573 WRITE_RPS1(CMD_WR_REG_MASK | (GPIO_CTRL>>2)); 574 WRITE_RPS1(GPIO3_MSK); 575 WRITE_RPS1(SAA7146_GPIO_OUTHI<<24); 576#if RPS_IRQ 577 // issue RPS1 interrupt 578 WRITE_RPS1(CMD_INTERRUPT); 579#endif 580 // Wait reset Source Line Counter Threshold (p36) 581 WRITE_RPS1(CMD_PAUSE | RPS_INV | EVT_HS); 582 // Set GPIO3=0 (p42) 583 WRITE_RPS1(CMD_WR_REG_MASK | (GPIO_CTRL>>2)); 584 WRITE_RPS1(GPIO3_MSK); 585 WRITE_RPS1(SAA7146_GPIO_OUTLO<<24); 586#if RPS_IRQ 587 // issue RPS1 interrupt 588 WRITE_RPS1(CMD_INTERRUPT); 589#endif 590 // Jump to begin of RPS program (p37) 591 WRITE_RPS1(CMD_JUMP); 592 WRITE_RPS1(dev->d_rps1.dma_handle); 593 594 // Fix VSYNC level 595 saa7146_setgpio(dev, 3, SAA7146_GPIO_OUTLO); 596 // Set RPS1 Address register to point to RPS code (r108 p42) 597 saa7146_write(dev, RPS_ADDR1, dev->d_rps1.dma_handle); 598 599 if (!(budget = kmalloc (sizeof(struct budget_patch), GFP_KERNEL))) 600 return -ENOMEM; 601 602 dprintk(2, "budget: %p\n", budget); 603 604 err = ttpci_budget_init(budget, dev, info, THIS_MODULE, adapter_nr); 605 if (err) { 606 kfree(budget); 607 return err; 608 } 609 610 // Set Source Line Counter Threshold, using BRS (rCC p43) 611 // It generates HS event every TS_HEIGHT lines 612 // this is related to TS_WIDTH set in register 613 // NUM_LINE_BYTE3 in budget-core.c.
