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

12Supported devices
13-----------------
14The ``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
22Boot options
23------------
24The ``xiangshan-kunminghu`` machine can start using the standard ``-bios``
25functionality for loading the boot image. You need to compile and link
26the firmware, kernel, and Device Tree (FDT) into a single binary file,
27such as ``fw_payload.bin``.
