+- Introduction
+
+ LoongArch is the general processor architecture of Loongson.
+
+ The following versions of the LoongArch core are supported
+ core: 3A5000
+ https://github.com/loongson/LoongArch-Documentation/releases/download/2021.08.17/LoongArch-Vol1-v1.00-EN.pdf
+
+ We can get the latest loongarch documents at https://github.com/loongson/LoongArch-Documentation/tags.
+
+
+- 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. Install LoongArch cross-tools on X86 machines.
+
+ Download cross-tools.
+
+ wget https://github.com/loongson/build-tools/releases/latest/download/loongarch64-clfs-20210831-cross-tools.tar.xz
+
+ tar -vxf loongarch64-clfs-20210831-cross-tools.tar.xz -C /opt
+
+ Config cross-tools env.
+
+ . setenv.sh
+
+ setenv.sh:
+
+ #!/bin/sh
+ set -x
+ CC_PREFIX=/opt/cross-tools
+
+ export PATH=$CC_PREFIX/bin:$PATH
+ export LD_LIBRARY_PATH=$CC_PREFIX/lib:$LD_LIBRARY_PATH
+ export LD_LIBRARY_PATH=$CC_PREFIX/loongarch64-unknown-linux-gnu/lib/:$LD_LIBRARY_PATH
+ set +x
+
+ 2. Test tests/tcg/multiarch.
+
+ ./configure --disable-rdma --disable-pvrdma --prefix=/usr \
+ --target-list="loongarch64-linux-user" \
+ --disable-libiscsi --disable-libnfs --disable-libpmem \
+ --disable-glusterfs --enable-libusb --enable-usb-redir \
+ --disable-opengl --disable-xen --enable-spice --disable-werror \
+ --enable-debug --disable-capstone --disable-kvm --enable-profiler
+
+ cd build/
+
+ make && make check-tcg
+
+ 3. Run LoongArch system basic command with loongarch-clfs-system.
+
+ Download clfs-system.
+
+ wget https://github.com/loongson/build-tools/releases/latest/download/loongarch64-clfs-system-2021-08-31.tar.bz2
+
+ tar -vxf loongarch64-clfs-system-2021-08-31.tar.bz2 -C /opt/clfs
+
+ Config env.
+
+ cp /opt/clfs/lib64/ld-linux-loongarch64.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
+ ...
+
+
+- Note.
+ We can get the latest LoongArch documents or LoongArch tools at https://github.com/loongson/
