README

1 - Introduction
2 
3   LoongArch is the general processor architecture of Loongson.
4 
5   The following versions of the LoongArch core are supported
6     core: 3A5000
7     https://github.com/loongson/LoongArch-Documentation/releases/download/2021.08.17/LoongArch-Vol1-v1.00-EN.pdf

12 - System emulation
13 
14   You can reference docs/system/loongarch/loongson3.rst to get the information about system emulation of LoongArch.
15 
16 - Linux-user emulation
17 
18   We already support Linux user emulation. We can use LoongArch cross-tools to build LoongArch executables on X86 machines,
19   and We can also use qemu-loongarch64 to run LoongArch executables.
20 
21   1. Config cross-tools env.
22 
23      see System emulation.
24 
25   2. Test tests/tcg/multiarch.
26 
27      ./configure  --static  --prefix=/usr  --disable-werror --target-list="loongarch64-linux-user" --enable-debug
28 
29      cd build
30 
31      make && make check-tcg
32 
33   3. Run LoongArch system basic command with loongarch-clfs-system.
34 
35      - Config clfs env.
36 
37        wget https://github.com/loongson/build-tools/releases/download/2022.05.29/loongarch64-clfs-system-5.0.tar.bz2
38 
39        tar -vxf loongarch64-clfs-system-5.0.tar.bz2 -C /opt/clfs
40 
41        cp /opt/clfs/lib64/ld-linux-loongarch-lp64d.so.1  /lib64
42 
43        export LD_LIBRARY_PATH="/opt/clfs/lib64"
44 
45      - Run LoongArch system basic command.
46 
47        ./qemu-loongarch64  /opt/clfs/usr/bin/bash
48        ./qemu-loongarch64  /opt/clfs/usr/bin/ls
49        ./qemu-loongarch64  /opt/clfs/usr/bin/pwd
