Paolo Bonzini	02d4a4a674	trace/ftrace: move snprintf+write from tracepoints to ftrace.c This simplifies the Python code and reduces the size of the tracepoints.

Lluís Vilanova	5b808275f3	trace: Multi-backend tracing Adds support to compile QEMU with multiple tracing backends at the same time. For example, you can compile QEMU with: $ ./configure --enable-trace-backends=ftrace,dtrace Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system. This patch allows having both available without recompiling QEMU. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>	12 years ago
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>	13 years ago
