- Support for Budget Patch (full TS) modification on
- SAA7146+AV7110 based cards (DVB-S cards). This
- driver doesn't use onboard MPEG2 decoder. The
- card is driven in Budget-only mode. Card is
- required to have loaded firmware to tune properly.
- Firmware can be loaded by insertion and removal of
- standard AV7110 driver prior to loading this
- driver.
-
- Say Y if you own such a card and want to use it.
-
- To compile this driver as a module, choose M here: the
- module will be called budget-patch.

-/* OLD (Original design by Roberto Deza):
-** This code will setup the SAA7146_RPS1 to generate a square
-** wave on GPIO3, changing when a field (TS_HEIGHT/2 "lines" of
-** TS_WIDTH packets) has been acquired on SAA7146_D1B video port;
-** then, this GPIO3 output which is connected to the D1B_VSYNC
-** input, will trigger the acquisition of the alternate field
-** and so on.
-** Currently, the TT_budget / WinTV_Nova cards have two ICs
-** (74HCT4040, LVC74) for the generation of this VSYNC signal,
-** which seems that can be done perfectly without this :-)).
-*/
-
-/* New design (By Emard)
-** this rps1 code will copy internal HS event to GPIO3 pin.
-** GPIO3 is in budget-patch hardware connected 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 reception 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 can't 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 frequency, 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 setting DD1_INIT trigger mode 7 in 3rd nibble.
