There are a number of free running counters introduced for uncore, which provide highly valuable information to a wide array of customers. However, the generic uncore code doesn't support them yet. The free running counters will be specially handled based on their unique attributes: - They are read-only. They cannot be enabled/disabled. - The event and the counter are always 1:1 mapped. It doesn't need to be assigned nor tracked by event_list. - They are always active. It doesn't need to check the availability. - They have different bit width. Also, using inline helpers to replace the check for fixed counter and free running counter.
