| """Script to build ChromeOS benchmarks |
| |
| Inputs: |
| chromeos_root |
| toolchain_root |
| board |
| [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 |
| |
| chromeos/browser/* |
| - Call build_chromebrowser to build image with new browser |
| - Copy image to perflab-bin |
