+# LoongArch QEMU virt platform
+
+## Overview
+
+  LoongArch QEMU virt is a generic platform that dose not require any actual hardware.
+  The minimum required QEMU version is [8.1](https://gitlab.com/qemu-project/qemu/-/tags), the minimum required GCC version is [GCC13](https://gcc.gnu.org/gcc-13/), the minimum required Binutils version is [2.40](https://ftp.gnu.org/gnu/binutils/).
+
+## Prepare (X86 Linux Environment)
+
+### Fedora39
+Install LoongArch64 cross compiler, LoongArch system QEMU.
+
+    yum install gcc-loongarch64-linux-gnu
+    yum install qemu-system-loongarch64
+
+### Others X86 OS ENV
+#### Configure cross-tools
+
+**Download:**
+
+    wget https://github.com/loongson/build-tools/releases/download/2023.08.08/x86_64-cross-tools-loongarch64-binutils_2.41-gcc_13.2.0.tar.xz
+
+**Configure the cross-tools environment:**
+
+    mkdir /opt/loongarch64_cross-toolchain/
+    tar -vxf x86_64-cross-tools-loongarch64-binutils_2.41-gcc_13.2.0.tar.xz -C /opt/loongarch64_cross-toolchain/
+    export PATH=/opt/loongarch64_cross-toolchain/cross-tools/bin:$PATH
+
+Note: Please obtain [the latest cross-compilation](https://github.com/loongson/build-tools) toolchains.
+
+#### Build QEMU
