| 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 \ |
