3.1.1. Setup

For this section, we'll assume you've already performed the basic setup outlined in the General Setup section.

In particular, you'll get the most mileage out of perf if you profile an image built with INHIBIT_PACKAGE_STRIP = "1" in your local.conf.

perf runs on the target system for the most part. You can archive profile data and copy it to the host for analysis, but for the rest of this document we assume you've ssh'ed to the host and will be running the perf commands on the target.
