2290  * http://212.227.36.83/linuxtv/wiki/index.php/DVB_TT_Budget_Patch
2291  * On the short description there is also a link to a external file,
2292  * with more details:
2293  * http://perso.wanadoo.es/jesussolano/Ttf_tsc1.zip
2294  *
2295  * New software triggering design by Emard that works on
2296  * original Roberto Deza's hardware:
2297  *
2298  * rps1 code for budgetpatch will copy internal HS event to GPIO3 pin.
2299  * GPIO3 is in budget-patch hardware connectd to port B VSYNC
2300  * HS is an internal event of 7146, accessible with RPS
2301  * and temporarily raised high every n lines
2302  * (n in defined in the RPS_THRESH1 counter threshold)
2303  * I think HS is raised high on the beginning of the n-th line
2304  * and remains high until this n-th line that triggered
2305  * it is completely received. When the receiption of n-th line
2306  * ends, HS is lowered.
2307  *
2308  * To transmit data over DMA, 7146 needs changing state at
2309  * port B VSYNC pin. Any changing of port B VSYNC will
2310  * cause some DMA data transfer, with more or less packets loss.
2311  * It depends on the phase and frequency of VSYNC and
2312  * the way of 7146 is instructed to trigger on port B (defined
2313  * in DD1_INIT register, 3rd nibble from the right valid
2314  * numbers are 0-7, see datasheet)
2315  *
2316  * The correct triggering can minimize packet loss,
2317  * dvbtraffic should give this stable bandwidths:
2318  *   22k transponder = 33814 kbit/s
2319  * 27.5k transponder = 38045 kbit/s
2320  * by experiment it is found that the best results
2321  * (stable bandwidths and almost no packet loss)
2322  * are obtained using DD1_INIT triggering number 2
2323  * (Va at rising edge of VS Fa = HS x VS-failing forced toggle)
2324  * and a VSYNC phase that occurs in the middle of DMA transfer
2325  * (about byte 188*512=96256 in the DMA window).
2326  *
2327  * Phase of HS is still not clear to me how to control,
2328  * It just happens to be so. It can be seen if one enables
2329  * RPS_IRQ and print Event Counter 1 in vpeirq(). Every
2330  * time RPS_INTERRUPT is called, the Event Counter 1 will
2331  * increment. That's how the 7146 is programmed to do event
2332  * counting in this budget-patch.c
2333  * I *think* HPS setting has something to do with the phase
2334  * of HS but I cant be 100% sure in that.
2335  *
2336  * hardware debug note: a working budget card (including budget patch)
2337  * with vpeirq() interrupt setup in mode "0x90" (every 64K) will
2338  * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes
2339  * and that means 3*25=75 Hz of interrupt freqency, as seen by
2340  * watch cat /proc/interrupts
2341  *
2342  * If this frequency is 3x lower (and data received in the DMA
2343  * buffer don't start with 0x47, but in the middle of packets,
2344  * whose lengths appear to be like 188 292 188 104 etc.
2345  * this means VSYNC line is not connected in the hardware.
2346  * (check soldering pcb and pins)
2347  * The same behaviour of missing VSYNC can be duplicated on budget
2348  * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble.

2773                  * only after we started a DMA xfer, and disable it here
2774                  * immediately, or it will be signalled all the time while
2775                  * DEBI is idle.
2776                  * Note 2: You would think that an irq which is masked is
2777                  * not signalled by the hardware. Not so for the SAA7146:
2778                  * An irq is signalled as long as the corresponding bit
2779                  * in the ISR is set, and disabling irqs just prevents the
2780                  * hardware from setting the ISR bit. This means a) that we
2781                  * must clear the ISR *after* disabling the irq (which is why
2782                  * we must do it here even though saa7146_core did it already),
2783                  * and b) that if we were to disable an edge triggered irq
2784                  * (like the gpio irqs sadly are) temporarily we would likely
2785                  * loose some. This sucks :-(
