| - 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 | |
