1. You need to create and boot an image for the target system, and run 
basic smoke tests (e.g. that you can log in, and the network is up and 
runing etc). We do this in a fully automated fashion when the target 
hardware is QEMU emulation of various machines:

bitbake -c testimage <image_name>

2. You need to place the benchmark software into the target image, by 
building and packaging it via yocto recipes that you need to write. I 
don't know if the recipes for benchmarks you mentioned are already 
available somewhere; in that case you can simply re-use that, and 
configure your image to include that. Then you boot the image on the 
target hardware and run the benchmarks.
