[chromeos/cpu/<benchname>|chromeos/browser/[pagecycler|sunspider]|chromeos/startup]
This script assumes toolchain has already been built in toolchain_root.
chromeos/cpu/<benchname>
- Execute bench.py script within chroot to build benchmark
- Copy build results to perflab-bin
chromeos/startup
- Call build_chromeos to build image.
- Copy image to perflab-bin
