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 \
