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.
Claims22
A method comprising:
- communicating over a serial interface with an input/output (I/O) extender;
- and
- saving a relevant status of the I/O extender in a memory.
An electronic appliance, comprising:
- a processor;
- an input/output (I/O) extender;
- an I/O device coupled with the I/O extender;
- and
- an interrupt engine coupled with the processor and the I/O extender, the interrupt engine to communicate with the I/O extender, to save a relevant status of the I/O extender in a memory, and to program software to respond to a change in the relevant status of the I/O extender.
A storage medium comprising content which, when executed by an accessing machine, causes the accessing machine to communicate over a serial interface with an input/output (I/O) extender, and save a relevant status of the I/O extender in a memory.
An apparatus, comprising:
- a serial interface;
- a processor interface;
- and
- control logic coupled with the serial and processor interfaces, the control logic to communicate through the serial interface with an input/output (I/O) extender and to save a relevant status of the I/O extender in a memory.
