Passthrough gpu with kvm

General infos

Using iommu technology to give a vm direct access to the gpu.

Crackq is an online distributed GPU-accelerated password cracker designed to help penetration testers and network auditors check for weak passwords. It supports a number of hash types and we are actively adding new algorithms.

This document describes a method of reading and displaying previously used framebuffers from a variety of popular graphics cards. In all 4 tested laptops the content of the VRAM was not erased upon reboot. It is also possible to show that the content of the host VRAM can be accessed from a VirtualBox guest, thereby leaking possibly confidential information from a trusted host into an untrusted guest machine.

Programming today exercises our symbolic reasoning. We write code—a sequence of symbols—in a text editor.

But when we explain ideas to colleagues, we don’t just speak words, we draw diagrams and gesture with our hands. We augment the symbolic channel with a spatial channel.

How can we communicate programs to a computer over a spatial channel?

Shadershop is an interface for programming GPU shaders in the mode of a direct manipulation image editor like Photoshop. It is an experiment in leveraging the programmer’s spatial reasoning the way that coding today leverages the programmer’s symbolic reasoning.

The evolution of the modern graphics processor begins with the introduction of the first 3D add-in cards in 1995, followed by the widespread adoption of the 32-bit operating systems and the affordable personal computer.

The graphics industry that existed before that largely consisted of a more prosaic 2D, non-PC architecture, with graphics boards better known by their chip’s alphanumeric naming conventions and their huge price tags. 3D gaming and virtualization PC graphics eventually coalesced from sources as diverse as arcade and console gaming, military, robotics and space simulators, as well as medical imaging.
