ABSTRACT:
In some embodiments, a method, apparatus and system to generate an interrupt by monitoring an external interface are presented. In this regard, an interrupt agent is introduced to communicate over a serial interface with an input/output (I/O) extender and to save a relevant status of the I/O extender in a memory. Other embodiments are also disclosed and claimed.
