The uncore subsystem in Haswell-EP is similar to Sandy/Ivy Bridge-EP. There are some differences in config register encoding and pci device IDs. The Haswell-EP uncore also supports a few new events. Add the Haswell-EP driver to the snbep split driver. Signed-off-by: NYan, Zheng <zheng.z.yan@intel.com> [ Add missing break. Add imc events.

Keeping track of all the various CPU names is hard enough; adding extra silly names for no reason is just not helping. If we know the base arch name (IvyBridge) then we can do the client/server parts with the well known {,EP,EX} postfixes, no need to remember endless amounts of unrelated and pointless names for this.

This patch exposes two basic events for Ivytown IMC uncore PMU: - cas_count_read: number of full-cache line reads to memory controller - cas_count_write: number of full-cache line writes to memory controller Those events use the same encoding as for SNB-EP, so reuse the same event table. See specification in: http://www.intel.com/content/dam/www/public/us/en/documents/manuals/xeon-e5-2600-v2-uncore-manual.pdf By aggregating all the read and write events from all the memory controllers of each processor socket, one can determine the total memory bandwidth utilization.
