README

- Introduction

LoongArch is the general processor architecture of Loongson.

The following versions of the LoongArch core are supported
core: 3A5000
https://github.com/loongson/LoongArch-Documentation/releases/download/2021.08.17/LoongArch-Vol1-v1.00-EN.pdf

We can get the latest loongarch documents at https://github.com/loongson/LoongArch-Documentation/tags.

- System emulation

You can reference docs/system/loongarch/loongson3.rst to get the information about system emulation of LoongArch.

- Linux-user emulation

We already support Linux user emulation. We can use LoongArch cross-tools to build LoongArch executables on X86 machines,
and We can also use qemu-loongarch64 to run LoongArch executables.

1. Config cross-tools env.

see System emulation.

2. Test tests/tcg/multiarch.

./configure --static --prefix=/usr --disable-werror --target-list="loongarch64-linux-user" --enable-debug

cd build

make && make check-tcg

3. Run LoongArch system basic command with loongarch-clfs-system.

- Config clfs env.

wget https://github.com/loongson/build-tools/releases/download/2022.05.29/loongarch64-clfs-system-5.0.tar.bz2

tar -vxf loongarch64-clfs-system-5.0.tar.bz2 -C /opt/clfs

cp /opt/clfs/lib64/ld-linux-loongarch-lp64d.so.1 /lib64

export LD_LIBRARY_PATH="/opt/clfs/lib64"

- Run LoongArch system basic command.

./qemu-loongarch64 /opt/clfs/usr/bin/bash
./qemu-loongarch64 /opt/clfs/usr/bin/ls
./qemu-loongarch64 /opt/clfs/usr/bin/pwd
