步驟如下：

$ cd
$ wget https://github.com/steward-fu/website/releases/download/miyoo-mini/toolchain.tar.gz
$ tar xvf toolchain.tar.gz
$ sudo mv mmiyoo /opt
$ sudo mv prebuilt /opt
$ export PATH=/opt/mmiyoo/bin/:$PATH

$ wget https://github.com/steward-fu/website/releases/download/miyoo-mini-plus/src_kernel-4.9.84.tar.gz
$ tar xvf src_kernel-4.9.84.tar.gz
$ cd kernel
$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make mmp_defconfig
$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make EXTRA_CFLAGS=-w clean
$ ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make EXTRA_CFLAGS=-w -C tools/perf

Perf依賴很多Libraries，因此，必須確保Buildroot都有編譯需要的元件庫
