To: linux-kernel; +Cc: peterz, mingo, ak, zheng.z.yan
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.

I changed that to the below; seeing how I have the uncore splitup
patches.
Also, I'm very tempted to do a s/ivt/ivbep/ on that whole thing. We
really should not mix all these stupid names.

Subject: perf/x86/uncore: Rename IvyTown to IvyBridge-EP
From: Peter Zijlstra <peterz@infradead.org>
Date: Tue Aug 12 09:15:25 CEST 2014
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.

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.
