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) { const int length = TS_WIDTH * TS_HEIGHT; struct pci_dev *pdev = dev->pci; struct av7110 *av7110; struct task_struct *thread; int ret, count = 0; dprintk(4, "dev: %p\n", dev); /* Set RPS_IRQ to 1 to track rps1 activity. * Enabling this won't send any interrupt to PC CPU. */ #define RPS_IRQ 0 if (budgetpatch == 1) { budgetpatch = 0; /* autodetect the presence of budget patch * this only works if saa7146 has been recently * reset with MASK_31 to MC1 * * will wait for VBI_B event (vertical blank at port B) * and will reset GPIO3 after VBI_B is detected. * (GPIO3 should be raised high by CPU to * test if GPIO3 will generate vertical blank signal * in budget patch GPIO3 is connected to VSYNC_B */ /* RESET SAA7146 */ saa7146_write(dev, MC1, MASK_31); /* autodetection success seems to be time-dependend after reset */ /* Fix VSYNC level */ saa7146_setgpio(dev, 3, SAA7146_GPIO_OUTLO); /* set vsync_b triggering */ saa7146_write(dev, DD1_STREAM_B, 0); /* port B VSYNC at rising edge */ saa7146_write(dev, DD1_INIT, 0x00000200); saa7146_write(dev, BRS_CTRL, 0x00000000); // VBI saa7146_write(dev, MC2, 1 * (MASK_08 | MASK_24) | // BRS control 0 * (MASK_09 | MASK_25) | // a 1 * (MASK_10 | MASK_26) | // b 0 * (MASK_06 | MASK_22) | // HPS_CTRL1 0 * (MASK_05 | MASK_21) | // HPS_CTRL2 0 * (MASK_01 | MASK_15) // DEBI ); /* start writing RPS1 code from beginning */ count = 0; /* Disable RPS1 */ saa7146_write(dev, MC1, MASK_29); /* RPS1 timeout disable */ saa7146_write(dev, RPS_TOV1, 0); WRITE_RPS1(CMD_PAUSE | EVT_VBI_B); 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 to increment counter */ WRITE_RPS1(CMD_INTERRUPT); #endif WRITE_RPS1(CMD_STOP); /* Jump to begin of RPS program as safety measure (p37) */ WRITE_RPS1(CMD_JUMP); WRITE_RPS1(dev->d_rps1.dma_handle); #if RPS_IRQ /* set event counter 1 source as RPS1 interrupt (0x03) (rE4 p53) * use 0x03 to track RPS1 interrupts - increase by 1 every gpio3 is toggled * use 0x15 to track VPE interrupts - increase by 1 every vpeirq() is called */ saa7146_write(dev, EC1SSR, (0x03<<2) | 3 ); /* set event counter 1 threshold to maximum allowed value (rEC p55) */ saa7146_write(dev, ECT1R, 0x3fff ); #endif /* Set RPS1 Address register to point to RPS code (r108 p42) */ saa7146_write(dev, RPS_ADDR1, dev->d_rps1.dma_handle); /* Enable RPS1, (rFC p33) */ saa7146_write(dev, MC1, (MASK_13 | MASK_29 )); mdelay(10); /* now send VSYNC_B to rps1 by rising GPIO3 */ saa7146_setgpio(dev, 3, SAA7146_GPIO_OUTHI); mdelay(10); /* if rps1 responded by lowering the GPIO3, * then we have budgetpatch hardware */ if ((saa7146_read(dev, GPIO_CTRL) & 0x10000000) == 0) { budgetpatch = 1; printk("dvb-ttpci: BUDGET-PATCH DETECTED.\n"); } /* Disable RPS1 */ saa7146_write(dev, MC1, ( MASK_29 )); #if RPS_IRQ printk("dvb-ttpci: Event Counter 1 0x%04x\n", saa7146_read(dev, EC1R) & 0x3fff ); #endif } /* prepare the av7110 device struct */ av7110 = kzalloc(sizeof(struct av7110), GFP_KERNEL); if (!av7110) { dprintk(1, "out of memory\n"); return -ENOMEM; } av7110->card_name = (char*) pci_ext->ext_priv; av7110->dev = dev; dev->ext_priv = av7110; ret = get_firmware(av7110); if (ret < 0) goto err_kfree_0; ret = dvb_register_adapter(&av7110->dvb_adapter, av7110->card_name, THIS_MODULE, &dev->pci->dev, adapter_nr); if (ret < 0) goto err_put_firmware_1; /* the Siemens DVB needs this if you want to have the i2c chips get recognized before the main driver is fully loaded */ saa7146_write(dev, GPIO_CTRL, 0x500000); strscpy(av7110->i2c_adap.name, pci_ext->ext_priv, sizeof(av7110->i2c_adap.name)); saa7146_i2c_adapter_prepare(dev, &av7110->i2c_adap, SAA7146_I2C_BUS_BIT_RATE_120); /* 275 kHz */ ret = i2c_add_adapter(&av7110->i2c_adap); if (ret < 0) goto err_dvb_unregister_adapter_2; ttpci_eeprom_parse_mac(&av7110->i2c_adap, av7110->dvb_adapter.proposed_mac); ret = -ENOMEM; /* full-ts mod?
