From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm sorry, I'm quite inexperienced when it comes to virtualisation. Can you please explain what you mean? Thanks.

I think they're referring to SR-IOV support (Single Root Input/Output Virtualization). It's a technology that allows a single hardware device, like a GPU, to be shared across multiple virtual machines (VMs) with minimal overhead. In short, it lets you split your GPU into smaller GPUs that you can then distribute to VMs. This, historically, has been the domain of enterprise and industrial applications, but that's changing. With Linux gaming on the rise, and more tech enthusiasts then ever, more and more people are trying virtualization and more and more consumers feel the need for SR-IOV. Right now, only a handful of expensive, enterprise-tier AMD GPUs have SR-IOV support. I believe it's the same situation with nVidia, but you can unlock the feature on their consumer GPUs with some third-party tool (AFAIK).

Oh yeah I heard about this and saw that mutahar (some ordinary gamers) was doing it once on windows with a 4090. I would love to do that on my GPU and then split it between my host and my VM

You summed it up better than I ever could. I'd give you lemmy gold if that was a thing.
