Robert Richter db98c5faf8 perf/x86: Implement 64-bit counter support for IBS ... This patch implements 64 bit counter support for IBS. The sampling period is no longer limited to the hw counter width. The functions perf_event_set_period() and perf_event_try_update() can be used as generic functions. They can replace similar code that is duplicate across architectures.
