Starfive ARM Linux for Gem5 FS Emulation

ATTENTION: We highly recommend you use Ubuntu-18.04 with gcc-7 to build the kernel. gcc-8 and later version does build the kernel successfully, but gem5 will refuse to boot!!

1. Prerequisites

if you use docker, run the following command:

apt update && apt upgrade && apt install build-essential make cmake ibncurses5-dev libncursesw5-dev gcc-arm-linux-gnueabihf gcc-aarch64-linux-gnu device-tree-compiler && unminimize

Otherwise:

sudo apt update && sudo apt upgrade && sudo apt install build-essential make cmake ibncurses5-dev libncursesw5-dev gcc-arm-linux-gnueabihf gcc-aarch64-linux-gnu device-tree-compiler

2. Kernel build

Before building the kernel, make sure you are currently on branch v4.15

cp arch/arm64/configs/starfive_gem5_numa_defconfig .config
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j 32

You can enjoy a cup of coffee while waiting. When it finishes successfully, newly built kernel can be found under the current directory called vmlinux
