Overview

RVVM - The RISC-V Virtual Machine

RISC-V Logo

RISC-V CPU & System software implementation written in С

What's working

  • OpenSBI, custom firmwares boot and execute properly
  • Linux kernel boots! Although, without clint & timer it does not run init

What's done so far

  • Feature-complete RV32I instruction set
  • C, M, A instruction extensions
  • Extendable and fast instruction decoder
  • Physical memory
  • Memory mapping unit (MMU) with SV32 virtual addressing
  • TLB address caching (greatly speeds up memory operations)
  • MMIO handlers
  • CSR operations
  • UART 16550a-compatible text console
  • Bootrom loading
  • DTB loading, passing to firmware/kernel
  • ELF kernel loading

Usage

Currently builds on *nix systems using GNU Make. Actual code however is cross-platform and more build targets are going to be supported, including Windows, or even embedded systems. The bootrom.bin file is a user-provided raw binary, loaded at 0x80000000 address where it starts execution, and device.dtb is a DTB file containing description of the machine.

git clone https://github.com/LekKit/RVVM
cd RVVM
make
cd release.linux.x86_64
./rvvm_x86_64 bootrom.bin -dtb=device.dtb

Our team

  • LekKit: Instruction decoding, RAM/MMU/TLB implementation, RV32ICA ISA, privileged ISA, lots of fixes
  • Mr0maks: Initial ideas, C/M extensions, VM debugger, CSR work
  • cerg2010cerg2010: ELF loading, important fixes and refactoring
  • Hoping to see more contributors here

TODO

  • Debug the available functionality and make sure it's conforming to the specs
  • Timer, CLINT
  • Successfully running Linux userspace software (currently hangs at "Freeing unused kernel memory; Run /init as init process")
  • Floating-point extensions
  • Refactor the code; Make internal APIs usable for both 32 & 64 bit VMs
  • Basic peripherals, some kind of storage
  • A lot more...
  • JIT? RV64? Userspace emulation?

  • Add Haiku host support

    Add Haiku host support

    I am an author of Haiku operating system RISC-V support and I am grad to see there are some interest in Haiku by RVVM developers.

    Test FreeBSD, HaikuOS (FreeBSD generic kernel boots but i have no idea how to mount rootfs, too lazy to look at Haiku)

    Some time ago I experimented in running Haiku in RVVM and got some results. First I made RVVM running on Haiku (patch is here). And then I try to adapt Haiku so it can run as guest in RVVM. Result can be seen in screenshot. It is not trivial to adapt Haiku guest for RVVM because Haiku ATA and PS/2 drivers code is very x86-centered, so patches are not yet upstreamed.

    Haiku is booted in RVVM by commad like this:

    rvvm -mem 512M -res 800x600 --rv64 \
-image haiku-minimum.image \
haiku_loader.riscv

    haiku_loader.riscv is Haiku boot loader for bare metal RISC-V virtual machines (TinyEMU and QEmu are currently fully supported). It is responsible for loading kernel, boot drivers, configuration and some hardware information.

    In this issue I only ask about Haiku host support, I think guest support should be done on Haiku side.

  • Absolute positioned input device support

    Absolute positioned input device support

    Currently RVVM support only relative-positioned PS/2 mouse emulation that require pointer capture. It is annoying and limiting because it do not work properly on touchscreens and tablets with digital pen. TinyEMU and QEmu supports absolute positioned pointer.

    It can be implemented with i2c HID or USB HID.

  • PLIC interrupts stop working after some time

    PLIC interrupts stop working after some time

    Tested on Haiku host and guest, no SMP guest.

  • Failed to build openSBI.

    Failed to build openSBI.

    Hi, I have built risc-v linux toolchain, linux kernel, and uBoot, and try to build openSBI. After generate fw_jump.bin in opensbi/build/platform/generic/firmware ./rvvm_riscv fw_jump.bin -kernel linux_Image -image rootfs.img -rv64 -mem 2G -smp 2 -res 1280x720 It will loop forever, like this OpenSBI

    Is this problem is caused by openSBI or RVMM and how can I successfully execute RVMM?

    many thanks!

    Hibernate / resume (and discussing other ideas)

    A neat feature that would probably be easier here than a real VM would be dumping memory and state to a hibernate file and allowing the VM to be resumed from that file. Would enable hot migrate of VMs, sleep/wake, etc.
