Does this mean that we cannot use oProfile to profile 4KE right now? Regards, Colin ^ permalink raw reply [flat|nested] 3+ messages in thread

The 4K processors don't implement performance counters which are required for any serious use of Oprofile. Lacking performance counters there is always the fallback option of using the timer interrupt but of course that means you won't be able to take advantage of much of Oprofile's fancyness.
