# -*- mode: makefile -*-
trace: switch to modular code generation for sub-directories Introduce rules in the top level Makefile that are able to generate trace.[ch] files in every subdirectory which has a trace-events file. The top level directory is handled specially, so instead of creating trace.h, it creates trace-root.h. This allows sub-directories to include the top level trace-root.h file, without ambiguity wrt to the trace.g file in the current sub-dir.

trace: fix make foo-timestamp rules The Makefile uses intermediate timestamp files to avoid rebuilding if tracetool output is unchanged. Timestamps are implemented incorrectly. This was fixed for rules.mak in commit 4b25966ab976f3a7fd9008193b2defcc82f8f04d ("rules.mak: cleanup config generation rules") but never fixed in trace/Makefile.objs. The problem with the old timestamp implementation was that make doesn't notice the updated file modification time until the next time it is run. It was necessary to run make twice in a row to achieve a full rebuild. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

# Backend code
trace: get rid of generated-events.h/generated-events.c Currently the generated-events.[ch] files contain the event dstates, constants and TraceEvent structs, while the generated-tracers.[ch] files contain the actual trace probe logic. With the removal of usage of the event enums from the API there is no longer any compelling reason for the separation between these files. The generated-events.h content is only ever needed from the generated-tracers.[ch] files. The enums/constants/structs from generated-events.[ch] are thus moved into the generated-tracers.[ch], so that there is one less file to be generated.

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>
