Build QEMU

# Clone the QEMU repository
git clone git@github.com:qemu/qemu.git 
cd qemu 
git checkout v10.0.0


python -m venv ./my-venv
source ./my-venv/bin/activate
pip install --upgrade setuptools
pip install --upgrade distlib

# Configure and build QEMU for riscv64
./configure --target-list=x86_64-softmmu   

make -j$(nproc)

deactivate
cd ..

Build buildroot

git clone git@github.com:buildroot/buildroot.git
cd buildroot
git checkout 56c6862bc81ef41c0fe012677eafa24381b1f76c

# use default configuration for RISC-V 64-bit virt QEMU/gem5
make qemu_x86_64_defconfig

sed -i 's/^BR2_TARGET_ROOTFS_EXT2_2=y/# BR2_TARGET_ROOTFS_EXT2_2 is not set/' .config

sed -i 's/.*BR2_TARGET_ROOTFS_EXT2_4.*/BR2_TARGET_ROOTFS_EXT2_4=y/' .config

make olddefconfig

make -j$(nproc)

Build linux kernel

git clone --depth 1 -b v6.8 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
cd linux

# generate default RISC-V configuration
make defconfig

# Compile both the vmlinux ELF (needed for debugging) and the Image (used as payload)
make CC="gcc -std=gnu11" HOSTCC="gcc -std=gnu11"  -j$(nproc)
