2291  * http://212.227.36.83/linuxtv/wiki/index.php/DVB_TT_Budget_Patch
2292  * On the short description there is also a link to a external file,
2293  * with more details:
2294  * http://perso.wanadoo.es/jesussolano/Ttf_tsc1.zip
2295  *
2296  * New software triggering design by Emard that works on
2297  * original Roberto Deza's hardware:
2298  *
2299  * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2300  * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2301  * HS is an internal event of 7146, accessible with RPS
2302  * and temporarily raised high every n lines
2303  * (n in defined in the RPS_THRESH1 counter threshold)
2304  * I think HS is raised high on the beginning of the n-th line
2305  * and remains high until this n-th line that triggered
2306  * it is completely received. When the receiption of n-th line
2307  * ends, HS is lowered.
2308  *
2309  * To transmit data over DMA, 7146 needs changing state at
2310  * port B VSYNC pin. Any changing of port B VSYNC will
2311  * cause some DMA data transfer, with more or less packets loss.
2312  * It depends on the phase and frequency of VSYNC and
2313  * the way of 7146 is instructed to trigger on port B (defined
2314  * in DD1_INIT register, 3rd nibble from the right valid
2315  * numbers are 0-7, see datasheet)
2316  *
2317  * The correct triggering can minimize packet loss,
2318  * dvbtraffic should give this stable bandwidths:
2319  *   22k transponder = 33814 kbit/s
2320  * 27.5k transponder = 38045 kbit/s
2321  * by experiment it is found that the best results
2322  * (stable bandwidths and almost no packet loss)
2323  * are obtained using DD1_INIT triggering number 2
2324  * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2325  * and a VSYNC phase that occurs in the middle of DMA transfer
2326  * (about byte 188*512=96256 in the DMA window).
2327  *
2328  * Phase of HS is still not clear to me how to control,
2329  * It just happens to be so. It can be seen if one enables
2330  * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2331  * time RPS_INTERRUPT is called, the Event Counter 1 will
2332  * increment. That's how the 7146 is programmed to do event
2333  * counting in this budget-patch.c
2334  * I *think* HPS setting has something to do with the phase
2335  * of HS but I cant be 100% sure in that.
2336  *
2337  * hardware debug note: a working budget card (including budget patch)
2338  * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2339  * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2340  * and that means 3*25=75 Hz of interrupt freqency, as seen by
2341  * watch cat /proc/interrupts
2342  *
2343  * If this frequency is 3x lower (and data received in the DMA
2344  * buffer don't start with 0x47, but in the middle of packets,
2345  * whose lengths appear to be like 188 292 188 104 etc.
2346  * this means VSYNC line is not connected in the hardware.
2347  * (check soldering pcb and pins)
2348  * The same behaviour of missing VSYNC can be duplicated on budget
2349  * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.
