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?
Sounds like you have an unacknowledged interrupt. Does it help if you call the
interrupt handler once after that your chip has been reset and configured?
Did you mean unacknowledged to chip or interrupt controller? Anyway
calling interrupt handler right after initialization does not seem to help.
Else sharing some of the source code might help.
