2009-02-26V4L/DVB (10694): [PATCH] software IRQ watchdog for Flexcop B2C2 DVB PCI cardsPatrick Boettcher
With (some) Technisat cards you cannot run multiple DVB applications in parallel and switch the channel at the same time. There seems to be a problem on the interfaces or even inside the flexcop-device that can't handle interruption on the streaming interface. This patch adds a watchdog to check whether data is supposed to come in (streaming PIDs are requested) and if no data is seen within 400ms (default) it resets the streaming/pid-filtering hardware. This patch is urgently needed to support the rev 2.8 of the hardware and solves problem occassionally seen on older hardware.

2005-07-07[PATCH] dvb: flexcop: woraround irq stop problemPatrick Boettcher
The flexcop chip often stops generating interrupts after some hours of operation. Apparently this can be fixed by resetting register block 0x300 at each channel change (this is not detailed in the flexcop data books). This patch also restructures DMA handling and adds a bit of debug code for the irq problem in case it still happens for someone.

2005-05-17[PATCH] dvb: flexcop: use hw pid filterJohannes Stezenbach
- enabled the HW PID by default for the PCI cards - correct the TS demux parsing when PID filter is enabled (and thus the timer IRQ) - rewrote the PID-filter and FULLTS control part in flexcop-hw-filter (thanks to Krzysztof Matula for pointing that out) Signed-off-by: Patrick Boettcher <pb@linuxtv.org> Signed-off-by: Johannes Stezenbach <js@linuxtv.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-17[PATCH] dvb: flexcop: fix USB transfer handlingJohannes Stezenbach
- driver receives many null TS packets (pid=0x1fff). They occupy the limited USB bandwidth and this leads to loss of video packets. Enabling the null packet filter fixes this. - packets that flexcop sends to USB have a 2 byte header that has to be removed. - sometimes a TS packet is split between different urbs. These parts have to be combined in a temporary buffer.
