QEMU with VirtIO GPU Vulkan Support

With its latest reales qemu added the Venus patches so that virtio-gpu now support venus encapsulation for vulkan. This is one more piece to the puzzle towards full Vulkan support.

An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for VirtIO-GPU with a local development environment. Following up on the outdated write up, this is how its done today.

The original snippet no longer works!

On 02/09/2024 at around 8pm UTC, Discord flipped an experiment (2023-09_mobile_redesign_override_toggles) which ignores the layout toggle that this script relied on.

If you want to continue using the old layout, you can either use a modded mobile client (such as Vendetta) to disable that experiment, or downgrade to an old version of the app.

Method 1 - Downgrading (Android)

Tip

Use this one if you want a fast, beginner-friendly solution and don't mind using a version from November 2023

1. Download version 205.15 of Discord mobile app from ApkMirror

This is a mini-tutorial of sorts for getting started with gdb on the Switch, with the target audience being people who want to mod and/or reverse games, with no prerequisite knowledge of gdb. The goal will be to walk you through some of the basic workflows needed to use a debugger on the Switch, while being brief enough for skimming for when you forget things.

If some part is unclear, your OS doesn't have install instructions, or you feel part of your workflow should be added here, feel free to comment any additions.

Installing GDB

First off you'll need a version of GDB compatible with aarch64. This can be obtained via either a distribution of

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.
