Abstract

Various embodiments are generally directed an apparatus and method for receiving an interrupt to cause a system event on a platform processing device from a device not operative to directly cause the system event on the platform processing device, generating a generic event 5 message having information based on the interrupt and in response to receiving the interrupt. Moreover a defined event message may be generated having information based on the information in the generic event message and interrupt may be sent to an operating system of the platform processing device to cause the system event on the platform processing device based on information in the defined event message.
