Embodiments of graphics instruction instrumentor (“GII”) and a graphics profiler (“GP”) are described. The GII may facilitate profiling of execution of graphics instructions by one or more graphics processors. The GII may identify target graphics instructions for which execution profile information is desired. The GII may store instrumentation graphics instructions in a graphics instruction buffer. The instrumentation graphics instructions may facilitate the GP in collecting graphics profile information. For example, timestamp-storage instructions may be store timestamps before and after execution of the target graphics instructions. The GII also may store an interrupt-generation instruction to cause an interrupt to be sent to the GP so that the GP may begin collection of graphics profile data. The GII may store an event-wait instruction to pause the graphics processors until an event is received. Other embodiments may be described and claimed. |
