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
