OS: Ubuntu 21.04

PC: NUC10

參考資料：https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel

Step0: 安裝Ubuntu 21.04

Step1-1: 設定編譯環境-修改 apt source list

Step1-2: 設定編譯環境

sudo apt-get build-dep linux linux-image-$(uname -r)

sudo apt-get install libncurses-dev gawk flex bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf

Step2: 根據目前內核版本取得linux source code

apt-get source linux-image-unsigned-$(uname -r)

Step3: 根據需要修改source code

Step4: 修改debian.master/changelog 中的 version number

5.11.0-25 -> 5.11.0.26
