perf/x86/uncore: Export basic memory events for IVT IMC PMU
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.
