Abstract
In-band event polling mechanism. A master device may initiate a polling transaction to poll at least a subset of a plurality of slave devices for event information. In response to the polling transaction, at least one of the subset of slave devices may transmit event information to the master device. The event information may correspond to at least one of a plurality of asynchronous event types. If the event type associated with the received event information is an event notification for an embedded processor of the master device, the master device may forward the event information to the embedded processor. Otherwise, if the event type associated with the received event information is an event notification for a device external to the master device (e.g., a host processor), the master device may translate the event information to a protocol associated with the event type and forward the event information to the external device.
