From b9e1ab6d4c0582cad97699285a6b3cf992251b00 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Tue, 11 Feb 2014 16:20:12 +0100 Subject: [PATCH] perf/x86/uncore: add SNB/IVB/HSW client uncore memory controller support This patch adds a new uncore PMU for Intel SNB/IVB/HSW client CPUs. It adds the Integrated Memory Controller (IMC) PMU. This new PMU provides a set of events to measure memory bandwidth utilization. The IMC on those processor is PCI-space based. This patch exposes a new uncore PMU on those processor: uncore_imc Two new events are defined: - name: data_reads - code: 0x1 - unit: 64 bytes - number of full cacheline read requests to the IMC - name: data_writes - code: 0x2 - unit: 64 bytes - number of full cacheline write requests to the IMC Documentation available at: http://software.intel.com/en-us/articles/monitoring-integrated-memory-controller-requests-in-the-2nd-3rd-and-4th-generation-intel Cc: mingo@elte.hu Cc: acme@redhat.com Cc: ak@linux.intel.com Cc: zheng.z.yan@intel.com Cc: peterz@infradead.org Signed-off-by: Stephane Eranian Signed-off-by: Peter Zijlstra Link: http://lkml.kernel.org/r/1392132015-14521-7-git-send-email-eranian@google.com Signed-off-by: Thomas Gleixner --- Reading git-format-patch failed
