I am a grad student whose research is mainly about memory hierarchy. To understand the latest eDram cache architecture in Haswell (e.g. i7-4770R) more, I was trying to use PMC to verify some detail in this paper: http://computingnow.computer.org/cms/Computer.org/ComputingNow/issues/2014/06/mmi2014020006.pdf. However, according to the Software Developer’s Manual, Ch. 19-3, there is no performance-monitoring event that is directly related to eDram cache. Is that just because the manual has not been updated? Or there is no such thing for eDram, and I have to measure performance metric for eDram by combinations of L3 stats and main memory stats?
Thanks for any help in advance.
