Perfetto for upstream kernel development

Perfetto is super useful for understanding interactions between the kernel and applications. Outside of Android and ChromeOS, though it's use isn't as common. This doc tries to provide a basic walk through to get started using perfetto for upstream kernel development with classic linux distros, potentially running under qemu.

Install perfetto

Grab the latest linux- tarball: https://github.com/google/perfetto/releases

Often the tests I’m tracing need to run as root, so because of this, I copied the binaries in the tarball to /usr/local/bin/ and chmod +x the binaries to make
