+- 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

+
+     - Run LoongArch system basic command.

+       ./qemu-loongarch64  /opt/clfs/usr/bin/bash
