# Overview

This repository contains the code to reproduce experiments in [the paper][paper]:

* GPU.zip: On the Side-Channel Implications of Hardware-Based Graphical Data Lossless Compression

## Preliminaries

* Required tool: perf, stress-ng

* Required shared libraries: OpenGL library (-lgl, core profile 3.3), GLFW library (-lglfw).

* Python virtual environment and package installation:

```bash

virtualenv -p python3 venv

source venv/bin/activate

pip install numpy

pip install matplotlib

pip install py-cpuinfo

```

## High level summary

1. `01-leakage-channel` reproduces Table 2, and Figure 2 and 3 in the paper.

2. `02-memory-stressor` reproduces Figure 4 in the paper.

3. `03-llc` reproduces Figure 5 in the paper.

5. `04-chrome-poc` contains the two PoCs in Section 5 of the paper. Reproducing Figure 14 and 15 can be done by uprobing Chrome and then run the PoCs with scripts and driver code similar to the ones in `01-leakage-channel`.

6. `poc` contains a OpenGL workload that attempts to trigger iGPU graphical data compression.

7. `uprobe-chromium` attaches a uprobe to the `Math.sqrt()` function in Chrome.

8. `i915-tools` documents our reverse-engineered proprietary compression algorithms of Intel and AMD iGPUs.

## Tested machine

1. `01-leakage-channel` is tested on an Intel i7-8700 (Ubuntu 22.04), i5-1135G7 (Debian 11.6), i7-12700K (Ubuntu 22.04), and AMD Ryzen 7 4800U (Ubuntu 20.04).

2. `02-memory-stressor` and `03-llc` are tested on an Intel i7-8700 (Ubuntu 22.04).

3. `04-chrome-poc` is tested on machines in Table 3 of the paper.

All tested machines are bare-metal machines. Running the code on other CPUs will likely require modification to the code (e.g., hardware measurement methodology).
