SAN19-223 Using Perf and its friend eBPF on Arm platform

Sign up or log in to save this to your schedule and see who's attending!

Perf has joined a growing number of tools able to act as userspace interface to eBPF. Not only that but it can also reprise its historic role as the best interface to the Linux performance monitoring sub-system to profile eBPF programs installed by itself or any other eBPF front end.

This session will mainly give updates for latest support for Arm CoreSight and eBPF in perf, and also will see how to Arm CoreSight can be used for eBPF program profiling.

This session will be divided into two main parts; the first part will focus on the updates for Arm CoreSight tracing, includes sample flags and integration perf for test support. In the bottom part, it will discuss the eBPF usage with perf tool: perf uses eBPF program for system call tracing; perf profiles the eBPF program by using the general PMU events and Arm CoreSight event.

This session will be finished within 25 minutes; in the CoreSight hacking session we will concentrate on questions
and demonstrations as the supplement to the presentation.
