2285 /* Budgetpatch note:
2286 * Original hardware design by Roberto Deza:
2287 * There is a DVB_Wiki at
2288 * https://linuxtv.org
2289 *
2290 * New software triggering design by Emard that works on
2291 * original Roberto Deza's hardware:
2292 *
2293 * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2294 * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2295 * HS is an internal event of 7146, accessible with RPS
2296 * and temporarily raised high every n lines
2297 * (n in defined in the RPS_THRESH1 counter threshold)
2298 * I think HS is raised high on the beginning of the n-th line
2299 * and remains high until this n-th line that triggered
2300 * it is completely received. When the reception of n-th line
2301 * ends, HS is lowered.
2302 *
2303 * To transmit data over DMA, 7146 needs changing state at
2304 * port B VSYNC pin. Any changing of port B VSYNC will
2305 * cause some DMA data transfer, with more or less packets loss.
2306 * It depends on the phase and frequency of VSYNC and
2307 * the way of 7146 is instructed to trigger on port B (defined
2308 * in DD1_INIT register, 3rd nibble from the right valid
2309 * numbers are 0-7, see datasheet)
2310 *
2311 * The correct triggering can minimize packet loss,
2312 * dvbtraffic should give this stable bandwidths:
2313 * 22k transponder = 33814 kbit/s
2314 * 27.5k transponder = 38045 kbit/s
2315 * by experiment it is found that the best results
2316 * (stable bandwidths and almost no packet loss)
2317 * are obtained using DD1_INIT triggering number 2
2318 * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2319 * and a VSYNC phase that occurs in the middle of DMA transfer
2320 * (about byte 188*512=96256 in the DMA window).
2321 *
2322 * Phase of HS is still not clear to me how to control,
2323 * It just happens to be so. It can be seen if one enables
2324 * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2325 * time RPS_INTERRUPT is called, the Event Counter 1 will
2326 * increment. That's how the 7146 is programmed to do event
2327 * counting in this budget-patch.c
2328 * I *think* HPS setting has something to do with the phase
2329 * of HS but I can't be 100% sure in that.
2330 *
2331 * hardware debug note: a working budget card (including budget patch)
2332 * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2333 * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2334 * and that means 3*25=75 Hz of interrupt frequency, as seen by
2335 * watch cat /proc/interrupts
2336 *
2337 * If this frequency is 3x lower (and data received in the DMA
2338 * buffer don't start with 0x47, but in the middle of packets,
2339 * whose lengths appear to be like 188 292 188 104 etc.
2340 * this means VSYNC line is not connected in the hardware.
2341 * (check soldering pcb and pins)
2342 * The same behaviour of missing VSYNC can be duplicated on budget
2343 * cards, by setting DD1_INIT trigger mode 7 in 3rd nibble.
