Hi, I trying to create small lirc (www.lirc.org) compatible CIR driver for it8705 chip (sits on ISA bus). My problem is I can not get interrupts coming to driver. I believe I configured chip (carrier freq. + baudrate divisor) and enabled interrupt mode the same way it windows driver does. It also seems to be correct according to chip specs. But nothing. vmstat -i shows zeros for assigned irq. And my IRS stay cold. I wrote small userland program which polls CIRs IIR (interrupt identefication register) and it shows interrupt pending bit set on right after I press key on remote control. Looks like I missed something fundamental. Does anyone can give me a hint where to look? Thanks, Alexander.
