directories:

- /compile/doc/stable-mt - the files in this dir

- /compile/source/linux-stable-mt7 - the kernel sources checked out from gitrepo

- /compile/result/stable-mt - the resulting kernel, modules etc. tar.gz files

- /compile/doc/kernel-config-options - https://github.com/hexdump0815/kernel-config-options

name: stb-mt7 - chromebook mediatek mt817x

it looks like for newer kernel versions like v6.5 the following packages have to be

installed in order to get the tool compiled well: libelf-dev python3-dev libtraceevent-dev

cd /compile/source/linux-stable-mt7
