This patch series provides access to various counters on the ThunderX SOC. For details of the uncore implementation see patch #1.
Patches #2-5 add the various ThunderX specific PMUs. As suggested I've put the files under drivers/perf/uncore. I would prefer this location over drivers/bus because not all of the uncore drivers are bus related. Changes to v1: - Added NUMA support - Fixed CPU hotplug by pmu migration - Moved files to drivers/perf/uncore - Removed OCX FRC and LNE drivers, these will fit better into a edac driver - improved comments abount overflow interrupts - removed max device limit - trimmed include files Feedback welcome!
