Abstract
A trace circuitry may be configured to receive a selection of one or more types of events possible in a processor core among multiple types of events. The trace circuitry may generate a message including trace information when an event corresponding to the selection occurs in the processor core. The trace information may include an address associated with the event and an indication of the type of event and/or cause for why the event occurred. In some implementations, the trace circuitry may use an event filter to pass events corresponding to the one or more types of events that are selected and block events corresponding to one or more types of events that are not selected. In some implementations, the trace circuitry may generate timestamps based on events to enable measurements between the events.
