37 $ME [-c <commit>] [-v] [-m <val>] [-j <val>] [-t <val>] [-i <image-name>] [-d <path>]
38Options:
39 -h
40 Display this help and exit.
41 -c <commit>
42 git checkout <commit> before anything else
43 -v
44 Show bitbake output, don't redirect it to a log.
45 -m <machine>
46 Value for MACHINE. Default is qemux86.
47 -j <val>
48 Value for PARALLEL_MAKE. Default is 8.
49 -t <val>
50 Value for BB_NUMBER_THREADS. Default is 8.
51 -i <image-name>
52 Instead of timing against core-image-sato, use <image-name>
53 -d <path>
54 Use <path> as DL_DIR
55 -p <githash>
56 Cherry pick githash onto the commit
57
58Note: current working directory must be inside a poky git clone.
