- Subject: User-space tracing on ARM
Hi
After using systemtap a lot to probe kernel, we would like to move on to user-space probing on ARM. This requires uprobes/utrace so I asked a few questions on utrace-devel mailing list. However this forum is also concerned:
- Is anyone probing user-space on ARM with systemtap ? I asked the question in the context of Linaro organization and I did not get anwers :-(
- how does systemtap compare to other tools for user-space ? I understand it may be the only front-end tool to dynamically instrument process functions through uprobes (or maybe LTTng with gdb tracepoints). In terms of perf, could be less good than tools focusing only on user-space but that is also a quality to focus on both kernel and user-space. And with regards to our amount of trace data, perf is not a key criteria.
Thanks for your inputs.
Regards
Fred
