2306 /* Budgetpatch note:
2307 * Original hardware design by Roberto Deza:
2308 * There is a DVB_Wiki at
2309 * http://212.227.36.83/linuxtv/wiki/index.php/Main_Page
2310 * where is described this 'DVB TT Budget Patch', on Card Modding:
2311 * http://212.227.36.83/linuxtv/wiki/index.php/DVB_TT_Budget_Patch
2312 * On the short description there is also a link to a external file,
2313 * with more details:
2314 * http://perso.wanadoo.es/jesussolano/Ttf_tsc1.zip
2315 *
2316 * New software triggering design by Emard that works on
2317 * original Roberto Deza's hardware:
2318 *
2319 * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2320 * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2321 * HS is an internal event of 7146, accessible with RPS
2322 * and temporarily raised high every n lines
2323 * (n in defined in the RPS_THRESH1 counter threshold)
2324 * I think HS is raised high on the beginning of the n-th line
2325 * and remains high until this n-th line that triggered
2326 * it is completely received. When the receiption of n-th line
2327 * ends, HS is lowered.
2328 *
2329 * To transmit data over DMA, 7146 needs changing state at
2330 * port B VSYNC pin. Any changing of port B VSYNC will
2331 * cause some DMA data transfer, with more or less packets loss.
2332 * It depends on the phase and frequency of VSYNC and
2333 * the way of 7146 is instructed to trigger on port B (defined
2334 * in DD1_INIT register, 3rd nibble from the right valid
2335 * numbers are 0-7, see datasheet)
2336 *
2337 * The correct triggering can minimize packet loss,
2338 * dvbtraffic should give this stable bandwidths:
2339 * 22k transponder = 33814 kbit/s
2340 * 27.5k transponder = 38045 kbit/s
2341 * by experiment it is found that the best results
2342 * (stable bandwidths and almost no packet loss)
2343 * are obtained using DD1_INIT triggering number 2
2344 * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2345 * and a VSYNC phase that occurs in the middle of DMA transfer
2346 * (about byte 188*512=96256 in the DMA window).
2347 *
2348 * Phase of HS is still not clear to me how to control,
2349 * It just happens to be so. It can be seen if one enables
2350 * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2351 * time RPS_INTERRUPT is called, the Event Counter 1 will
2352 * increment. That's how the 7146 is programmed to do event
2353 * counting in this budget-patch.c
2354 * I *think* HPS setting has something to do with the phase
2355 * of HS but I cant be 100% sure in that.
2356 *
2357 * hardware debug note: a working budget card (including budget patch)
2358 * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2359 * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2360 * and that means 3*25=75 Hz of interrupt freqency, as seen by
2361 * watch cat /proc/interrupts
2362 *
2363 * If this frequency is 3x lower (and data received in the DMA
2364 * buffer don't start with 0x47, but in the middle of packets,
2365 * whose lengths appear to be like 188 292 188 104 etc.
2366 * this means VSYNC line is not connected in the hardware.
2367 * (check soldering pcb and pins)
2368 * The same behaviour of missing VSYNC can be duplicated on budget
2369 * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.
