# benchmark for yocto build machine
This project includes a jenkins pipeline file for a yocto build. This pipeline can be used for a build of minimal yocto image and allows you to compare different build machine and setups of your machine.

## The build contains following stages:

| # | name | decription |
| -------- | -------- | -------- |
| 1 | clone sources  |  clone the yocto sources from github |
| 1 | fetch sources  |  download all required sources for the yocto build. This step ensures that a slow download does not affect the build time measurement.    |
| 1 | build image    |  build yocto image |

## parameter

You can specify a download path for downloaded source packages and git repositorys. 
This saves time in case of multiple calls of the benchmark.

## used yocto configuration

* Machine: qemux86
* Distro: poky
* yocto version: sumo
* image: core-image-minimal
