+BOSC Xiangshan Kunminghu FPGA prototype platform (``xiangshan-kunminghu``)
+==========================================================================
+The ``xiangshan-kunminghu`` machine is compatible with our FPGA prototype
+platform.
+
+XiangShan is an open-source high-performance RISC-V processor project.
+The third generation processor is called Kunminghu. Kunminghu is a 64-bit
+RV64GCBSUHV processor core. More information can be found in our Github
+repository:
+https://github.com/OpenXiangShan/XiangShan
+
+Supported devices
+-----------------
+The ``xiangshan-kunminghu`` machine supports the following devices:
+
+* Up to 16 xiangshan-kunminghu cores
+* Core Local Interruptor (CLINT)
+* Incoming MSI Controller (IMSIC)
+* Advanced Platform-Level Interrupt Controller (APLIC)
+* 1 UART
+
+Boot options
+------------
+The ``xiangshan-kunminghu`` machine can start using the standard ``-bios``
+functionality for loading the boot image. You need to compile and link
+the firmware, kernel, and Device Tree (FDT) into a single binary file,
+such as ``fw_payload.bin``.
+
+Running
+-------
+Below is an example command line for running the ``xiangshan-kunminghu``
+machine:
+
+.. code-block:: bash
+
+   $ qemu-system-riscv64 -machine xiangshan-kunminghu \
+      -smp 16 -m 16G \
+      -bios path/to/opensbi/platform/generic/firmware/fw_payload.bin \
+      -nographic
