#virgl — Public Fediverse posts

I figured I'd dump this into the void, but has anyone out there successfully done 3d accelerated virtio graphics with a NixOS host?

So … while this is obviously nice for virtualized gaming, what about video decode/encode acceleration?

Is there a way to give a #Linux guest access to the host #GPU's video codec acceleration without GPU passthrough?

Just like it's possible to pass /dev/dri into a container, can I do a similar thing with a #QEMU / #KVM virtual machine?

Notes on Setting up Xrdp PulseAudio on Fedora Silverblue

I’ve been playing with Bazzite inside Proxmox, and that led me to try and set up xrdp with glamor and pulseaudio on a new, headless Fedora Silverblue VM that I intend to use as a ML sandbox.(...)

Sooo, does #VirGL support routing the video output of a #vm to a monitor on the same machine? Or is it only to use a #gpu in the vm? I may have my understanding wrong. All I want to do is get #Proxmox to share it's video card (whichever I have two) with a VM so I can use it on a real screen. If I told you how many hours I spent on this already... 😢

So, it appears that virgl acceleration with virt-manager is broken on hosts running X11. But my favorite Desktop Manager doesn't come in Wayland flavor! #X11 #Wayland #virgl #virtio

Not sure what your screen size limits are but I think that #virgl can output up to 4k. However it looks like only some VM's have out of box support for hardware acceleration (Fedora had it, but Ubuntu doesn't seem to have it). You could probably get it going by installing the right guest drivers though

Drag and drop works out of the box for me. It's actually quite beautiful. This is all with the flatpak build which makes it really accessible

Step by step. First I've work in the continuous integration of #virgl and after some time work also in the CI of #mesa. Due to the work made and to do, I gained the developer chevron in mesa a few weeks a go. Now it is time to explore the #kernel used by #mesa. I'll do my best to make it easy to be as upstream as possible

Coming up on day 2 of #LinaroConnect, Gert Wollny presents "De-mystifying GFX-virtualization with VirGL"! Join us at 9:00 UTC! https://connect.linaro.org #LVC21F #Linux #Virtualization #VirGL #OpenGL

And we're off! September's busy conference schedule kicks off next week with Linaro Virtual Connect. Join us as we look at how to master your #PipeWire streams with #WirePlumber and de-mystify GFX virtualization with #VirGL! Registration is free! https://col.la/lvcf21 #LVC21F

Collabora has been investing into #Perfetto to enable driver authors and users to get deep insights into driver internals & GPU performance. Here's how we applied this work to study workloads on the virtualized #VirGL implementation. https://col.la/o3dvg #virglrenderer #opengl

Recently, we have been using #Perfetto to successfully profile Apitrace traces in #crosvm through #VirGL renderer. The tools provided by Perfetto can be very effective for profiling virtualised GPU acceleration. Antonio Caggiano explains how: https://col.la/virglperfetto #virglrenderer #gpu #opengl #opensourcesoftware

I made a quick demo video of #virgl under #qemu #tcg emulation of #arm64. Command line in the description: https://www.youtube.com/watch?v=WagWiCBuVB0
