This presentation shows new way for perf to handle sampled binaries. It eases up report from different servers and deprecates the usage of perf archive. With the help of debuginfod, sampled binaries can be downloaded directly to reporting server.
The main idea is that build ids of sampled binaries are stored directly in related map events, which speeds up and simplifies perf record. I'll explain current and new ways of handling sampled binaries, that should ease up life for customer support.
Jiri works for RedHat full time on Linux as kernel generalist engineer in Brno office, Czech Republicech Republic. He currently divides his work time between upstream perf work and maintaining RHEL perf.
