When the receiption 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 freqency, 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 seting DD1_INIT trigger mode 7 in 3rd nibble. - */ -static int __devinit av7110_attach(struct saa7146_dev* dev, - struct saa7146_pci_extension_data *pci_ext) -{ - const int length = TS_WIDTH * TS_HEIGHT;
