+- 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
