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