Dynamic tracers, such as perf, systemtap, bcc and more, help Linux developers to analyze both system performance and functional issues clearly. They can be attached lively to pre-built kernel/application binaries that have no pre-implemented probe point, and also can be easily customized because of their simple and modern script-based interface. In spite of rapid improvement of dynamic tracers in a past few years, few detailed documents about architecture other than Intel x86/64 have been reported. Several bottlenecks to solve remain in porting them to other architecture, such as compilation, dependencies, kind of bugs, and so on. In this session, Hiroyuki first describes a brief summary of recent updates of dynamic tracers, and then introduces a guide to port and to use them on ARM/AArch64 platform. Finally, he proposes some improvements and future issues.
