From 3d256151471ba9fd60a5b896a706eb21a6b1cea1 Mon Sep 17 00:00:00 2001 From: Nikolaus Voss Date: Wed, 3 Sep 2008 12:50:32 +0200 Subject: Add kernel support for oprofile callgraphs on AVR32 This patch adds backtracing capability to oprofile profiling in kernel and user mode on AVR32. This is done by going through the frames on the stack and adding oprofile traces for all return addresses. The code being profiled has to be compiled with frame pointers to make this work.
