📘 Terraform - Infrastructure as Code (IaC)

---

🧩 What is Terraform?

Terraform is an open-source Infrastructure as Code (IaC) tool developed by HashiCorp that allows you to define, provision, and manage cloud infrastructure using a declarative configuration language known as HCL (HashiCorp Configuration Language).

Instead of manually creating AWS resources (like EC2 instances, S3 buckets, Lambda functions, etc.) through the AWS console, Terraform allows you to write .tf files and version control your infrastructure just like application code.

Perfetto for upstream kernel development

Perfetto is super useful for understanding interactions between the kernel and applications. Outside of Android and ChromeOS, though it's use isn't as common. This doc tries to provide a basic walk through to get started using perfetto for upstream kernel development with classic linux distros, potentially running under qemu.

Install perfetto

Grab the latest linux- tarball: https://github.com/google/perfetto/releases

Often the tests I’m tracing need to run as root, so because of this, I copied the binaries in the tarball to /usr/local/bin/ and chmod +x the binaries to make

Running Windows 10/11 Guest with GPU Passthrough using laptop running Fedora

Abstract

This is a full guide for people who wanted to set up Windows 10/11 VM with QEMU/KVM hypervisor enhancements for a laptop that is configured with hybrid graphics card like Intel/AMD + NVIDIA. This process will take about 1 to 2 hours, depending on your system's performance and your patience =)

There is another comprehensive guide you can follow here (shoutout to asus-linux team who made supergfxctl which is a very important tool for this guide). It is more up-to-date than mine. I would probably incorporate those information into my guide, but you are welcome to use this one as a reference!

Before we proceed:

• This guide is exclusively for Fedora users because this distro is quite different to set up than other distro such as Arch. I would say Arch is easier to setup than Fedora, but sometimes you like to use Fedora than Arc
