There is GPIO coming from the host and from the cpld. Both of these interfaces are interruptable. The GXP is able to monitor PSU's via I2C. There is support for up to 8 PSUs. The GXP gets presence information from I/O with the cpld. The fan controller and the psu monitor consume I/O from the CPLD. Thus for the GXP to be able to report this GPIO to the OpenBMC stack calls have been enabled for the GPIO driver to use.
