The Flexcop writes to first - address and triggers an IRQ when it's full and starts writing to the second - address. When the second address is full, the IRQ is triggered again, and - the flexcop writes to first address again, and so on. - The buffersize of each address is currently 640*188 bytes. - - Problem is, when using hw-pid-filtering and doing some low-bandwidth - operation (like scanning) the buffers won't be filled enough to trigger - the IRQ. That's why: - - When PID filtering is activated, the timer IRQ is used. Every 1.97 ms the IRQ - is triggered. Is the current write address of DMA1 different to the one - during the last IRQ, then the data is passed to the demuxer. - - There is an additional DMA-IRQ-method: packet count IRQ. This isn't - implemented correctly yet. - - The solution is to disable HW PID filtering, but I don't know how the DVB - API software demux behaves on slow systems with 45MBit/s TS. - -Solved bugs :) --------------- -1g) pid-filtering (somehow pid index 4 and 5 (EMM_PID and ECM_PID) aren't -working) -SOLUTION: also index 0 was affected, because net_translation is done for -these indexes by default - -5b) isochronous transfer does only work in the first attempt (for the Sky2PC -USB, Air2PC is working) SOLUTION: the flexcop was going asleep and never really -woke up again (don't know if this need fixes, see -flexcop-fe-tuner.c:flexcop_sleep) - -NEWS: when the driver is loaded and unloaded and loaded again (w/o doing -anything in the while the driver is loaded the first time), no transfers take -place anymore. - -Improvements when rewriting (refactoring) is done -================================================= - -- split sleeping of the flexcop (misc_204.ACPI3_sig = 1;) from lnb_control - (enable sleeping for other demods than dvb-s) -- add support for CableStar (stv0297 Microtune 203x/ALPS) (almost done, incompatibilities with the Nexus-CA) - -Debugging ---------- -- add verbose debugging to skystar2.c (dump the reg_dw_data) and compare it - with this flexcop, this is important, because i2c is now using the - flexcop_ibi_value union from flexcop-reg.h (do you have a better idea for - that, please tell us so). - -Everything which is identical in the following table, can be put into a common -flexcop-module. - - PCI USB -------------------------------------------------------------------------------- -Different: -Register access: accessing IO memory USB control message -I2C bus: I2C bus of the FC USB control message -Data transfer: DMA isochronous transfer -EEPROM transfer: through i2c bus not clear yet - -Identical: -Streaming: accessing registers -PID Filtering: accessing registers -Sram destinations: accessing registers -Tuner/Demod: I2C bus -DVB-stuff: can be written for common use - -Acknowledgements (just for the rewriting part) -================ - -Bjarne Steinsbo thought a lot in the first place of the pci part for this code -sharing idea. - -Andreas Oberritter for providing a recent PCI initialization template -(pluto2.c). - -Boleslaw Ciesielski for pointing out a problem with firmware loader. - -Vadim Catana for correcting the USB transfer. - -comments, critics and ideas to linux-dvb@linuxtv.org. diff --git a/Documentation/dvb/technisat.txt b/Documentation/dvb/technisat.txt index cdf6ee4b2da..3f435ffb289 100644 --- a/Documentation/dvb/technisat.txt +++ b/Documentation/dvb/technisat.txt @@ -1,5 +1,5 @@ -How to set up the Technisat devices -=================================== +How to set up the Technisat/B2C2 Flexcop devices +================================================ 1) Find out what device you have ================================ @@ -16,54 +16,60 @@ DVB: registering frontend 0 (Conexant CX24123/CX24109)...
