[linux-dvb] Re: [PATCH] dvb-ttpci+budgetpatch integrated v32
HI
This patch is just keeping up-to-date with
recent pusi_seen fix included in the CVS
This budgetpatch is working stable during
all my tests. Anybody can suggest some astra
transponder that has both video and ip pids?
I'd be glad to try how they work at the same
time over 2 simultaneous DMA channels on the
same 7146.

+ * 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:
+ *
+ * this rps1 code 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.
