[LinuxPPS] GPIO PPS Generator

Hi all,
I'd like to test time synchronization of my two embedded systems
(Pandaboards). I thought connecting two Oscilloscope channels to the
GPIOs and use PPS to pules the GPIO.

I have several questions :

1) Is there a GPIO PPS enerator support in the kernel. I can see only
the one that uses Parallel port

2) Would GPIO interruption introduce too big jitter for
synchronization to be tested this way.

Best regards,
