The RISC-V Server Platform specification[1] defines a standardized set
of hardware and software capabilities, that portable system software,
such as OS and hypervisors can rely on being present in a RISC-V server
platform.
A corresponding Qemu RISC-V server platform reference (rvsp-ref for
short) machine type is added to provide a environment for firmware/OS
development and testing. The main features included in rvsp-ref are:
- Based on riscv virt machine type
- A new memory map as close as virt machine as possible
- A new virt CPU type rvsp-ref-cpu for server platform compliance
- AIA
- PCIe AHCI
- PCIe NIC
- No virtio device
- No fw_cfg device
- No ACPI table provided
- Only minimal device tree nodes
