2271  * http://212.227.36.83/linuxtv/wiki/index.php/DVB_TT_Budget_Patch
2272  * On the short description there is also a link to a external file,
2273  * with more details:
2274  * http://perso.wanadoo.es/jesussolano/Ttf_tsc1.zip
2275  *
2276  * New software triggering design by Emard that works on
2277  * original Roberto Deza's hardware:
2278  *
2279  * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2280  * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2281  * HS is an internal event of 7146, accessible with RPS
2282  * and temporarily raised high every n lines
2283  * (n in defined in the RPS_THRESH1 counter threshold)
2284  * I think HS is raised high on the beginning of the n-th line
2285  * and remains high until this n-th line that triggered
2286  * it is completely received. When the receiption of n-th line
2287  * ends, HS is lowered.
2288  *
2289  * To transmit data over DMA, 7146 needs changing state at
2290  * port B VSYNC pin. Any changing of port B VSYNC will
2291  * cause some DMA data transfer, with more or less packets loss.
2292  * It depends on the phase and frequency of VSYNC and
2293  * the way of 7146 is instructed to trigger on port B (defined
2294  * in DD1_INIT register, 3rd nibble from the right valid
2295  * numbers are 0-7, see datasheet)
2296  *
2297  * The correct triggering can minimize packet loss,
2298  * dvbtraffic should give this stable bandwidths:
2299  *   22k transponder = 33814 kbit/s
2300  * 27.5k transponder = 38045 kbit/s
2301  * by experiment it is found that the best results
2302  * (stable bandwidths and almost no packet loss)
2303  * are obtained using DD1_INIT triggering number 2
2304  * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2305  * and a VSYNC phase that occurs in the middle of DMA transfer
2306  * (about byte 188*512=96256 in the DMA window).
2307  *
2308  * Phase of HS is still not clear to me how to control,
2309  * It just happens to be so. It can be seen if one enables
2310  * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2311  * time RPS_INTERRUPT is called, the Event Counter 1 will
2312  * increment. That's how the 7146 is programmed to do event
2313  * counting in this budget-patch.c
2314  * I *think* HPS setting has something to do with the phase
2315  * of HS but I cant be 100% sure in that.
2316  *
2317  * hardware debug note: a working budget card (including budget patch)
2318  * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2319  * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2320  * and that means 3*25=75 Hz of interrupt freqency, as seen by
2321  * watch cat /proc/interrupts
2322  *
2323  * If this frequency is 3x lower (and data received in the DMA
2324  * buffer don't start with 0x47, but in the middle of packets,
2325  * whose lengths appear to be like 188 292 188 104 etc.
2326  * this means VSYNC line is not connected in the hardware.
2327  * (check soldering pcb and pins)
2328  * The same behaviour of missing VSYNC can be duplicated on budget
2329  * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.

2755                  * DEBI is idle.
2756                  * Note 2: You would think that an irq which is masked is
2757                  * not signalled by the hardware. Not so for the SAA7146:
2758                  * An irq is signalled as long as the corresponding bit
2759                  * in the ISR is set, and disabling irqs just prevents the
2760                  * hardware from setting the ISR bit. This means a) that we
2761                  * must clear the ISR *after* disabling the irq (which is why
2762                  * we must do it here even though saa7146_core did it already),
2763                  * and b) that if we were to disable an edge triggered irq
2764                  * (like the gpio irqs sadly are) temporarily we would likely
2765                  * loose some. This sucks :-(
