From 5ac59a8a77e3faa1eaf9bfe82a61e9396b082c3d Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Wed, 6 Feb 2013 15:46:01 +0100 Subject: perf tools: Add cpu_map processor socket level functions This patch adds: - cpu_map__get_socket: get socked id from cpu - cpu_map__build_socket_map: build socket map - cpu_map__socket: gets acutal socket from logical socket Those functions are used by uncore and processor socket-level aggregation modes.
