From 241771ef016b5c0c83cd7a4372a74321c973c1e6 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 3 Dec 2008 10:39:53 +0100 Subject: performance counters: x86 support Implement performance counters for x86 Intel CPUs. It's simplified right now: the PERFMON CPU feature is assumed, which is available in Core2 and later Intel CPUs. The design is flexible to be extended to more CPU types as well.
