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An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for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 Following up on the outdated write up, this is how its done today.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

Slack Tweaks

In Fall 2023, Slack introduced an updated client with some unpopular UI changes. The tweaks in this document can be used to revert to the old client or hide the new side bar. These will reset every time you fully close Slack but they are easy to re-apply once you get the hang of it.

(Cross Platform) Open Dev Tools [Preferred Option]

To run any of these scripts, you'll need to open the Dev Tools (or Console). You can do this by typing /slackdevtools in a Slack channel or direct message. These are the same Dev Tools you'd get in Chrome if you hit F12. Along the top are tabs for Elements, Console, Sources, Network, etc. You'll want to paste these scripts into the Console tab at the > prompt.

If Slack disables this command, then you can open Dev Tools by setting a system-wide environment variable and using a keyboard shortcut to open the console. If /slackdevtools worked for you then you can skip these next two sections.

(Mac OS) Enable Dev Mode

This is about running 8BitDo's Firmware Update tool for Windows in Wine. It can be used for updating newer 8BitDo devices that may not be supported by fwupd on Linux. This tool uses .NET Framework, so it will need Wine Mono to be installed (dotnet48 wintericks verb was tested to work as well).

This tool needs Segoe UI Symbol font, on Arch this font is provided by ttf-ms-win10-auto package. For other distributions there is install script.

You will have to let Wine access device's HID interface for updating the firmware. Most importantly it should be a boot HID interface (exposed when device is in bootloader mode, often referred to as "manual update mode" or "advanced mode"). It is also worth adding the Product IDs for HID interfaces that are exposed under different conditions (for example, Ultimate Bluetooth Controller's receiver exposes a HID interface when controller is not connected),

A guide to building and using the audio-enabled "Screamer" fork of PowerPC QEMU on macOS and Windows

Last updated: 2021/10/09 (QEMU-screamer version 6.1.50)

Here's a quickly-written guide describing how to build and use mcayland's excellent "Screamer" fork of QEMU which adds working audio support to QEMU for PowerPC guests!

Yes, this means working audio in PowerPC versions of OS X, Mac OS 9, and even Linux!

This guide isn't… quite up to my quality standards yet, but I figured I'd release it in this state regardless for anyone that might benefit from it, especially since I had to figure out quite a bit of this myself due to some of the existing documentation being somewhat outdated or incorrect.

Install Dafang Hacks on the Wyze Cam.

Once running and all is functional, continue. Set video bitrate to 1500, VBR, 30fps.
