2240  * where is described this 'DVB TT Budget Patch', on Card Modding:
2241  * http://212.227.36.83/linuxtv/wiki/index.php/DVB_TT_Budget_Patch
2242  * On the short description there is also a link to a external file,
2243  * with more details:
2244  * http://perso.wanadoo.es/jesussolano/Ttf_tsc1.zip
2245  *
2246  * New software triggering design by Emard that works on
2247  * original Roberto Deza's hardware:
2248  *
2249  * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2250  * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2251  * HS is an internal event of 7146, accessible with RPS
2252  * and temporarily raised high every n lines
2253  * (n in defined in the RPS_THRESH1 counter threshold)
2254  * I think HS is raised high on the beginning of the n-th line
2255  * and remains high until this n-th line that triggered
2256  * it is completely received. When the receiption of n-th line
2257  * ends, HS is lowered.
2258  *
2259  * To transmit data over DMA, 7146 needs changing state at
2260  * port B VSYNC pin. Any changing of port B VSYNC will
2261  * cause some DMA data transfer, with more or less packets loss.
2262  * It depends on the phase and frequency of VSYNC and
2263  * the way of 7146 is instructed to trigger on port B (defined
2264  * in DD1_INIT register, 3rd nibble from the right valid
2265  * numbers are 0-7, see datasheet)
2266  *
2267  * The correct triggering can minimize packet loss,
2268  * dvbtraffic should give this stable bandwidths:
2269  *   22k transponder = 33814 kbit/s
2270  * 27.5k transponder = 38045 kbit/s
2271  * by experiment it is found that the best results
2272  * (stable bandwidths and almost no packet loss)
2273  * are obtained using DD1_INIT triggering number 2
2274  * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2275  * and a VSYNC phase that occurs in the middle of DMA transfer
2276  * (about byte 188*512=96256 in the DMA window).
2277  *
2278  * Phase of HS is still not clear to me how to control,
2279  * It just happens to be so. It can be seen if one enables
2280  * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2281  * time RPS_INTERRUPT is called, the Event Counter 1 will
2282  * increment. That's how the 7146 is programmed to do event
2283  * counting in this budget-patch.c
2284  * I *think* HPS setting has something to do with the phase
2285  * of HS but I cant be 100% sure in that.
2286  *
2287  * hardware debug note: a working budget card (including budget patch)
2288  * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2289  * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2290  * and that means 3*25=75 Hz of interrupt freqency, as seen by
2291  * watch cat /proc/interrupts
2292  *
2293  * If this frequency is 3x lower (and data received in the DMA
2294  * buffer don't start with 0x47, but in the middle of packets,
2295  * whose lengths appear to be like 188 292 188 104 etc.
2296  * this means VSYNC line is not connected in the hardware.
2297  * (check soldering pcb and pins)
2298  * The same behaviour of missing VSYNC can be duplicated on budget
2299  * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.
