|
-c <commit>
|
||
|
|
git checkout <commit> before anything else
|
||
|
|
-v
|
||
|
|
Show bitbake output, don't redirect it to a log.
|
||
|
|
-m <machine>
|
||
|
|
Value for MACHINE. Default is qemux86.
|

-j <val>
|
||
|
|
Value for PARALLEL_MAKE. Default is 8.
|
||
|
|
-t <val>
|
||
|
|
Value for BB_NUMBER_THREADS. Default is 8.
|
||
|
|
-i <image-name>
|
||
|
|
Instead of timing against core-image-sato, use <image-name>
|
||
|
|
-d <path>
|
||
|
|
Use <path> as DL_DIR
|
||
|
|
-p <githash>
|
||
|
|
Cherry pick githash onto the commit
