QEMU with VirtIO GPU Vulkan Support

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An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for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 Following up on the outdated write up, this is how its done today.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

Rem This may mess up Linux GRUB. You might need to reinstall GRUB afterwards.
Rem Open Diskpart
diskpart
Rem Select your disk number, in my case #0
list disk
sel disk 0
Rem Select your disk number, in my case #2, you should recognize it by its size and by the filesystem (FAT32)

Recently, we've been working on extracting Ember conventions from applications we're working on into the framework. Our goal is to make it clearer how the parts of an Ember application work together, and how to organize and bootstrap your objects.

Routing

Routing is an important part of web applications. It allows your users to share the URL they see in their browser, and have the same things appear when their friends click on the link.

The Ember.js ecosystem has several great solutions for routing. But, since it is such an important part of most web applications, we've decided to build it right into the framework.

If you have already modeled your application state using Ember.StateManager, there are a few changes you'll need to make to enable routing. Once you've made those changes, you'll notice the browser's address bar spring to life as you start using your app—just by moving between states, Ember.js will update the URL automatically.
