Deobfuscating / Unminifying Obfuscated Web App / JavaScript Code

Some notes and tools for reverse engineering / deobfuscating / unminifying obfuscated web app code.

VFIO

Not KVM bound. The VFIO API deconstructs a device into regions, irqs, etc. The userspace application (QEMU, cloud-hypervisor, etc..) is responsible for reconstructing it into a device for e.g. a guest VM to consume.

Boot with intel_iommu=on.

IOMMU groups

Devices are bound together for isolation, IOMMU capabilities and platform topology reasons. It is not configurable.

TDP and Turbo Parameter Modification with MSR on Non-Overclockable CPUs

Disclaimer

Modifying MSR may void your CPU's (or system board's) warranty. Proceed with caution. I am not responsible for any damage caused by this article.
MSR addresses vary significantly between CPUs. Check your CPU's MSR address using Intel's documentation.
This has only been tested on the Intel i7-8550U (Kaby Lake R).
This article is a translation of this article. If you can read Korean, I recommend reading that article instead.

Introduction

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
