Hello everyone, I am currently fiddling around with performance monitoring on a Xeon Machine with an e5-2600 series CPU.
What I understand from Intel's uncore performance monitoring guide and from Andi Kleen's Readmes from his super useful pmu-tools, it is not possible to differentiate PCIe traffic per core when using the uncore PMUs (the CBo boxes to be precise). It is only possible per socket. I wonder, however, if it would be possible to at least make an educated guess of which core is producing how much PCIe or MMIO traffic. Maybe by cross-correlating with some PMU evens from core-resident PMUs? The amount of PMU events and configuration options is quite overwhelming, that's why I would appreciate any hints I can get :) Cheers, Andre -- To unsubscribe from this list: send the line "unsubscribe linux-perf-users" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
