- 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
|
