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An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for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 Following up on the outdated write up, this is how its done today.

Let's start with the brief description of the projects mentioned in the post & extend them:

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

How to use this gist

You've got two main options:

Hyperv Linux Guest GPU PV

Create VM

$isopath = <iso location>
$vhdpath = <vhdx location>
$vmpath = <vm path>
$vmname = "Arch-dxgkrnl"
New-VM -Name $vmname -MemoryStartupBytes 8GB -BootDevice VHD -NewVHDPath $vhdpath -Path $vmpath -NewVHDSizeBytes 20GB -Generation 2 -Switch "Default Switch"

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
