Abstract
Embodiments for memory bandwidth monitoring extensible counters are described. In embodiments, an apparatus includes memory bandwidth monitoring hardware to monitor an event, a shared cache to be shared by multiple cores. At least one of the cores is to execute multiple threads and includes at least three registers. The first register is programmable by software to store a thread identifier of one of threads and an event identifier of the event during execution of the thread. At least one value of the event identifier corresponds to a shared cache miss. The second register is to provide to the software a second value corresponding to a number of bits available to represent the count. The third register is to provide to the software a count of occurrences of the event and an indicator to indicate whether the count reached a maximum count representable by the number of bits.
