# Hazelnut

A semi-prototype of CollabVM 3.0 agent functionality (specifically display).

Currently NVIDIA-specific (since we use NvFBC); support for DXGI duplication (for post Win7) should be added at some point.

The agent runs on Windows 7 x64 onwards. Lower (or x86) is currently not supported as a target.

The agent uses IVSHMEM to provide frames to the client in a low-latency fashion. 

Later on virtio-serial may be considered for low-bandwidth additional functionality, like input. For now, however, the agent is display only.

This repository contains:

- The agent. Written in C++20.
- Shared headers and utility code, used between the agent and the client. Written in C++20, mostly so it can be shared between the agent and client.
- A Rust crate for Hazelnut clients to use. Wraps the Shared code.
- A test client written in Rust which displays the framebuffer (in a quick-and-dirty fashion.).
