| 1 | BOSC Xiangshan Kunminghu FPGA prototype platform (``xiangshan-kunminghu``) |
| 2 | ========================================================================== |
| 3 | The ``xiangshan-kunminghu`` machine is compatible with our FPGA prototype |
| 4 | platform. |
| 5 | |
| 6 | XiangShan is an open-source high-performance RISC-V processor project. |
| 7 | The third generation processor is called Kunminghu. Kunminghu is a 64-bit |
| 8 | RV64GCBSUHV processor core. More information can be found in our Github |

| 12 | Supported devices |
| 13 | ----------------- |
| 14 | The ``xiangshan-kunminghu`` machine supports the following devices: |
| 15 | |
| 16 | * Up to 16 xiangshan-kunminghu cores |
| 17 | * Core Local Interruptor (CLINT) |
| 18 | * Incoming MSI Controller (IMSIC) |
| 19 | * Advanced Platform-Level Interrupt Controller (APLIC) |
| 20 | * 1 UART |
| 21 | |
| 22 | Boot options |
| 23 | ------------ |
| 24 | The ``xiangshan-kunminghu`` machine can start using the standard ``-bios`` |
| 25 | functionality for loading the boot image. You need to compile and link |
| 26 | the firmware, kernel, and Device Tree (FDT) into a single binary file, |
| 27 | such as ``fw_payload.bin``. |
| 28 | |
| 29 | Running |
| 30 | ------- |
| 31 | Below is an example command line for running the ``xiangshan-kunminghu`` |
| 32 | machine: |
| 33 | |
| 34 | .. code-block:: bash |
| 35 | |
| 36 | $ qemu-system-riscv64 -machine xiangshan-kunminghu \ |
| 37 | -smp 16 -m 16G \ |
