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 can't 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. */ static int av7110_attach(struct saa7146_dev *dev, struct saa7146_pci_extension_data *pci_ext) { … } static int av7110_detach(struct saa7146_dev *saa) { … } static void av7110_irq(struct saa7146_dev *dev, u32 *isr) { … } static struct saa7146_extension av7110_extension_driver; #define MAKE_AV7110_INFO(x_var, x_name) … MAKE_AV7110_INFO(tts_1_X_fsc, "Technotrend/Hauppauge WinTV DVB-S rev1.X or Fujitsu Siemens DVB-C"); MAKE_AV7110_INFO(ttt_1_X, "Technotrend/Hauppauge WinTV DVB-T rev1.X"); MAKE_AV7110_INFO(ttc_1_X, "Technotrend/Hauppauge WinTV Nexus-CA rev1.X"); MAKE_AV7110_INFO(ttc_2_X, "Technotrend/Hauppauge WinTV DVB-C rev2.X"); MAKE_AV7110_INFO(tts_2_X, "Technotrend/Hauppauge WinTV Nexus-S rev2.X"); MAKE_AV7110_INFO(tts_2_3, "Technotrend/Hauppauge WinTV Nexus-S rev2.3"); MAKE_AV7110_INFO(tts_1_3se, "Technotrend/Hauppauge WinTV DVB-S rev1.3 SE"); MAKE_AV7110_INFO(ttt, "Technotrend/Hauppauge DVB-T"); MAKE_AV7110_INFO(fsc, "Fujitsu Siemens DVB-C"); MAKE_AV7110_INFO(fss, "Fujitsu Siemens DVB-S rev1.6"); MAKE_AV7110_INFO(gxs_1_3, "Galaxis DVB-S rev1.3"); static const struct pci_device_id pci_tbl[] = …; MODULE_DEVICE_TABLE(pci, pci_tbl); static struct saa7146_extension av7110_extension_driver = …; static int __init av7110_init(void) { … } static void __exit av7110_exit(void) { … } module_init(…) …; module_exit(av7110_exit); MODULE_DESCRIPTION(…) …; MODULE_AUTHOR(…) …; MODULE_LICENSE(…) …;
