+** 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.
