eVisor is a light-weight Bare Metal Hypervisor (Type 1) written in C++. This project is aimed for embedded use (ARM64 devices) and educational purposes.
eVisor demo video @ Youtube - NuttX runs on Raspberry Pi4
- Raspberry Pi 4 Model B (BCM2711 / aarch64 only)
- QEMU (ARM64)
- Switch to clang/llvm from gcc
- Support multi CPU cores
- Fix temporary implementation of memory management APIs like kmm_malloc
- Add Hypervisor system call APIs like KVM
- Full support for vCPU interrupts
- Support GIC version 3 and 4
- Improve scheduling algorithm
- Improve mmc device driver (SD data transfer speed)
- Support Linux OS
- Restructuring / refactoring source code
