gpu-tlb

This repo contains the tools described in our paper "TunneLs for Bootlegging: Fully Reverse-Engineering GPU TLBs for Challenging Isolation Guarantees of NVIDIA MIG".

• dumper: This utility tool can dump the memory of GPUs from the Ampere series and earlier.
• extractor: This utility tool can extract the GPU page tables from a given GPU memory dump.
• modifier: This tool is used to update the PTE values in GPU memory.
• examples: We provide several examples illustrating how to use our tools to explore GPU TLB properties.
