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/virt.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
- Note.
