From 950b8354716eb1f9c0b39777d379efa5f4125c04 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Wed, 22 Jan 2014 21:58:46 +0200 Subject: [PATCH] perf tools: Demangle kernel and kernel module symbols too Some kernels contain C++ code, and thus their symbols need to be demangled. This allows 'perf kvm top' to generate readable output.
