When the reception of n-th line ** ends, HS is lowered. ** To transmit data over DMA, 7146 needs changing state at ** port B VSYNC pin. Any changing of port B VSYNC will ** cause some DMA data transfer, with more or less packets loss. ** It depends on the phase and frequency of VSYNC and ** the way of 7146 is instructed to trigger on port B (defined ** in DD1_INIT register, 3rd nibble from the right valid ** numbers are 0-7, see datasheet) ** ** The correct triggering can minimize packet loss, ** dvbtraffic should give this stable bandwidths: ** 22k transponder = 33814 kbit/s ** 27.5k transponder = 38045 kbit/s ** by experiment it is found that the best results ** (stable bandwidths and almost no packet loss) ** are obtained using DD1_INIT triggering number 2 ** (Va at rising edge of VS Fa = HS x VS-failing forced toggle) ** and a VSYNC phase that occurs in the middle of DMA transfer ** (about byte 188*512=96256 in the DMA window). ** ** Phase of HS is still not clear to me how to control, ** It just happens to be so. It can be seen if one enables ** RPS_IRQ and print Event Counter 1 in vpeirq(). Every ** time RPS_INTERRUPT is called, the Event Counter 1 will ** increment. That's how the 7146 is programmed to do event ** counting in this budget-patch.c ** I *think* HPS setting has something to do with the phase ** of HS but I cant be 100% sure in that. ** hardware debug note: a working budget card (including budget patch) ** with vpeirq() interrupt setup in mode "0x90" (every 64K) will ** generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes ** and that means 3*25=75 Hz of interrupt frequency, as seen by ** watch cat /proc/interrupts ** ** If this frequency is 3x lower (and data received in the DMA ** buffer don't start with 0x47, but in the middle of packets, ** whose lengths appear to be like 188 292 188 104 etc. ** this means VSYNC line is not connected in the hardware. ** (check soldering pcb and pins) ** The same behaviour of missing VSYNC can be duplicated on budget ** cards, by setting DD1_INIT trigger mode 7 in 3rd nibble. */ // Setup RPS1 "program" (p35) count = 0; // Wait Source Line Counter Threshold (p36) WRITE_RPS1(CMD_PAUSE | EVT_HS); // Set GPIO3=1 (p42) WRITE_RPS1(CMD_WR_REG_MASK | (GPIO_CTRL>>2)); WRITE_RPS1(GPIO3_MSK); WRITE_RPS1(SAA7146_GPIO_OUTHI<<24); #if RPS_IRQ // issue RPS1 interrupt WRITE_RPS1(CMD_INTERRUPT); #endif // Wait reset Source Line Counter Threshold (p36) WRITE_RPS1(CMD_PAUSE | RPS_INV | EVT_HS); // Set GPIO3=0 (p42) WRITE_RPS1(CMD_WR_REG_MASK | (GPIO_CTRL>>2)); WRITE_RPS1(GPIO3_MSK); WRITE_RPS1(SAA7146_GPIO_OUTLO<<24); #if RPS_IRQ // issue RPS1 interrupt WRITE_RPS1(CMD_INTERRUPT); #endif // Jump to begin of RPS program (p37) WRITE_RPS1(CMD_JUMP); WRITE_RPS1(dev->d_rps1.dma_handle); // Fix VSYNC level saa7146_setgpio(dev, 3, SAA7146_GPIO_OUTLO); // Set RPS1 Address register to point to RPS code (r108 p42) saa7146_write(dev, RPS_ADDR1, dev->d_rps1.dma_handle); if (!(budget = kmalloc (sizeof(struct budget_patch), GFP_KERNEL))) return -ENOMEM; dprintk(2, "budget: %p\n", budget); if ((err = ttpci_budget_init (budget, dev, info, THIS_MODULE))) { kfree (budget); return err; } // Set Source Line Counter Threshold, using BRS (rCC p43) // It generates HS event every TS_HEIGHT lines // this is related to TS_WIDTH set in register // NUM_LINE_BYTE3 in budget-core.c.
