Subject: No serial port interrupts in /proc/interrupts
Date: Fri, 29 Feb 2008 20:08:17 +0100 [thread overview]
Message-ID: <20080229190817.81180@gmx.net> (raw)
Hi,
I'm wondering why the serial port interrupts don't show up in
/proc/interrupts or in debugfs/powerpc/virq_mapping. I added some debugging
code to the relevant code in arch/powerpc/kernel/irq.c and of_serial.c and
it looks like irq_of_parse_and_map() returns valid virqs (irq3, irq4 on a
i8259) for the two ns16550 compatible UARTs. Is there anything else to do,
to correctly implement UART support for a platform?
regards,
Gerhard
