Eiichi Tsukata 781e9545db trace: Add ftrace tracing backend ... This patch adds a ftrace tracing backend which sends trace event to ftrace marker file. You can effectively compare qemu trace data and kernel(especially, kvm.ko when using KVM) trace data. The ftrace backend is restricted to Linux only. To try out the ftrace backend: $ ./configure --trace-backend=ftrace $ make if you use KVM, enable kvm events in ftrace: # sudo echo 1 > /sys/kernel/debug/tracing/events/kvm/enable After running qemu by root user, you can get the trace: # cat /sys/kernel/debug/tracing/trace Signed-off-by: Eiichi Tsukata <eiichi.tsukata.xh@hitachi.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>		2013-05-03 13:58:09 +02:00
