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An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for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 Following up on the outdated write up, this is how its done today.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

Forenote: Most of the following is simply my point of view as an emulator developer. Various names are omitted for privacy reasons.

I usually write blog posts aimed at developers, but I'd like to make an exception just this once. For a lot of game consoles you have likely noticed that there's multiple emulators for said console. Even for more modern systems like the Nintendo 3DS, you've got several active emulators such as Citra, Mikage and Panda3DS, and some less active ones at the moment such as Corgi3DS. This has made many people in the emulation community ask "Why do emulator developers not simply collaborate"? Thus, I'd like to dedicate this post to answering this question as an emulator developer myself.

1) We actually do collaborate!

Even when we're working on different emulators, we very often collaborate and help each other. A lot of people don't know, since it usually happens ov

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

Patching the Youtube App

In short

Extract the main NSO
Convert it into an ELF (to strip header/hashes)
Load it into Ida, find the function and patch the bytes back into the binary
Convert the ELF back into NSO
Use the nso as exefs patch or re-import it into the NCA/NSP

This downloads standalone MSVC compiler, linker & other tools, also headers/libraries from Windows SDK into portable folder, without installing Visual Studio. Has bare minimum components - no UWP/Store/WindowsRT stuff, just files & tools for native desktop app development.

Run py.exe portable-msvc.py and it will download output into msvc folder. By default it will download latest available MSVC & Windows SDK - currently v14.40.33807 and v10.0.26100.0.

You can list available versions with py.exe portable-msvc.py --show-versions and then pass versions you want with --msvc-version and --sdk-version arguments.

To use cl.exe/link.exe first run setup_TARGET.bat - after that PATH/INCLUDE/LIB env variables will be updated to use all the tools as usual. You can also use clang-cl.exe with these includes & libraries.

To use clang-cl.exe without running setup.bat, pass extra /winsysroot msvc argument (msvc is folder name where output is stored).
