Talkat Embedded Linux Conference + OpenIoT Summit North America 2017 · on Wednesday, 2017-02-22· at 16:20· Skyline II·
summary
Describes recent updates to dynamic tracers (perf, systemtap, bcc) and explains how to port and use them on ARM/AArch64, covering practical issues like compilation problems, dependencies, and architecture-specific bugs. Presents a guide for adapting those tools from x86/64 to ARM/AArch64 and outlines proposed improvements and remaining challenges.
