This workload builds mesa with Meson/Ninja. There is one build and it completes within a minute. Looks like a classic parallel compile followed by a link step.
Topdown profile shows a mix of frontend and backend stalls and a relatively low retirement rate.
AMD metrics shows little floating point, and a matched frontend and backend stalls.
