[linux-dvb] Question about DVB-S and IRQ

[Martin Theodor Grewe <m.grewe@gmx.de>]

I'am using a Nexus 2.1 in my VDR,
here you can see some output while loading the drivers:

Dec 28 07:22:17 freeway kernel: Linux video capture interface: v1.00
Dec 28 07:22:17 freeway kernel: saa7146: register extension 'dvb'.
Dec 28 07:22:17 freeway kernel: ACPI: PCI interrupt 0000:03:02.0[A] -> 
GSI 18 (level, low) -> IRQ 18

DVB-S)...
Dec 28 07:22:18 freeway kernel: dvb-ttpci: found av7110-0.


What means: "kernel: dvb-ttpci: gpioirq unknown type=0 len=0" ??
Source says: IRQ for firmware - default etc. Can someone explain this?
