Hello, Please bear with me if this is a naive question. I am working on an embedded ARM chip (1GB ram, 2CPUs) where I want to collect trace events for a long duration of time. From the research that I have done (mostly reading papers on LTTng tracing, conference talks and documentation) I have seen it mentioned that for ARM the overhead is greater because the system call to get the CPU is quite slow. In my use case I am okay with not having this information. The current benchmarks show a 3 microsecond overhead of a single tracepoint on ARM in comparison to 150ns on a x86 machine. Hence, my question is: Is it possible to disable recording the CPU somehow? Any suggestions for decreasing the overhead other than this are welcome.
Regards, Aditya
