2310 /* Budgetpatch note:
2311 * Original hardware design by Roberto Deza:
2312 * There is a DVB_Wiki at
2313 * http://www.linuxtv.org/
2314 *
2315 * New software triggering design by Emard that works on
2316 * original Roberto Deza's hardware:
2317 *
2318 * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2319 * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2320 * HS is an internal event of 7146, accessible with RPS
2321 * and temporarily raised high every n lines
2322 * (n in defined in the RPS_THRESH1 counter threshold)
2323 * I think HS is raised high on the beginning of the n-th line
2324 * and remains high until this n-th line that triggered
2325 * it is completely received. When the receiption of n-th line
2326 * ends, HS is lowered.
2327 *
2328 * To transmit data over DMA, 7146 needs changing state at
2329 * port B VSYNC pin. Any changing of port B VSYNC will
2330 * cause some DMA data transfer, with more or less packets loss.
2331 * It depends on the phase and frequency of VSYNC and
2332 * the way of 7146 is instructed to trigger on port B (defined
2333 * in DD1_INIT register, 3rd nibble from the right valid
2334 * numbers are 0-7, see datasheet)
2335 *
2336 * The correct triggering can minimize packet loss,
2337 * dvbtraffic should give this stable bandwidths:
2338 * 22k transponder = 33814 kbit/s
2339 * 27.5k transponder = 38045 kbit/s
2340 * by experiment it is found that the best results
2341 * (stable bandwidths and almost no packet loss)
2342 * are obtained using DD1_INIT triggering number 2
2343 * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2344 * and a VSYNC phase that occurs in the middle of DMA transfer
2345 * (about byte 188*512=96256 in the DMA window).
2346 *
2347 * Phase of HS is still not clear to me how to control,
2348 * It just happens to be so. It can be seen if one enables
2349 * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2350 * time RPS_INTERRUPT is called, the Event Counter 1 will
2351 * increment. That's how the 7146 is programmed to do event
2352 * counting in this budget-patch.c
2353 * I *think* HPS setting has something to do with the phase
2354 * of HS but I can't be 100% sure in that.
2355 *
2356 * hardware debug note: a working budget card (including budget patch)
2357 * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2358 * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2359 * and that means 3*25=75 Hz of interrupt freqency, as seen by
2360 * watch cat /proc/interrupts
2361 *
2362 * If this frequency is 3x lower (and data received in the DMA
2363 * buffer don't start with 0x47, but in the middle of packets,
2364 * whose lengths appear to be like 188 292 188 104 etc.
2365 * this means VSYNC line is not connected in the hardware.
2366 * (check soldering pcb and pins)
2367 * The same behaviour of missing VSYNC can be duplicated on budget
2368 * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.
