Tested-by: Ferruh Yigit <ferruh.yi...@amd.com> Thanks for the update, output is now easier to consume with the help of the 'devtools/draw-dependency-graphs.py' script. A detail but script is not actually drawing graph, but parsing .dot file, name is a little misleading. Also for the patches that are converting explicit dependency to implicit dependency, I can see the benefit for the meson and graph. But also there is a value of keeping explicit dependency, it was an easy way to document dependencies of component for developers. So, I am not really sure which one is better.
