RVVM – RISC-V virtual machine

RVVM is a virtual machine / emulator for RISC-V guests, which emphasizes on performance, security, lean code and portability.

It already runs a lot of guest operating systems, including Linux, Haiku, FreeBSD, OpenBSD, etc. It also aims to run RISC-V applications on a foreign-arch host without full OS guest & isolation (Userland emulation).

This is free and open source software.

Key Features

• Fully spec-compliant rv64imafdcb instruction set, Zkr/Zicbom/Zicboz/Sstc extensions.
• Tracing JIT with x86_64, ARM64, RISC-V backends – Faster than QEMU TCG.
• Working OpenSBI & U-Boot, Linux, FreeBSD, OpenBSD, Haiku guests.
• Framebuffer display, HID mouse & keyboard, UART terminal.
• NVMe storage drives, TRIM support (Deallocate space on host), fast multi-threaded IO.
• Networking userland stack (Works on any host OS).
• VFIO PCIe passthrough (For GPUs, etc).
• Kernel-level isolation to prevent and contain vulnerability exploitation.
• Library API (librvvm) for machine/userland emulation, implementing new devices.
• Userland emulation (WIP).
• Shadow pagetable acceleration (WIP).
