In an apparatus performing multi-threaded data processing event handling circuitry receives event information from the data processing circuitry indicative of an event which has occurred during the data processing operations. Visibility configuration storage holds a set of visibility configuration values, each visibility configuration value associated with a thread of the multiple threads and the event handling circuitry adapts its use of the event information to restrict visibility of the event information for software of threads other than the thread which generated the event information when a visibility configuration value for the thread which generated the event information has a predetermined value. This allows multi-threaded event monitoring to be supported, whilst protecting event information from a particular thread for which it is desired to limit its visibility to software of other threads. |
