Abstract

Disclosed is a method that uses control logic to selectively steer detected PCI-Express hot-plug events to one of three interrupt types. Benefits include support of standard PCI interrupts, low overhead by service routines, and firmware-based system specific event signaling mechanisms in the absence of OS PCI interrupt support.
