Testing non-auto built docker containers (i.e. custom built compilers) is a bit fiddly as you couldn't continue a build with a previously locally built container. While you can play games with REGISTRY its simpler to allow a NOFETCH that will go through the cached build process when you run the tests.

We try to avoid using cpu_loop_exit_atomic as it brings in an all-core sync point. However on some cpu/kernel/benchmark combinations it is starting to show up in the performance profile. To make it easier to see whats going on add tracepoints for the slow path so we can see what is triggering the wait.
