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.

Those who custom configure their kernel: what did you gain? (lemmy.ml)

Curious to know the coolest things you achieved by configuring your kernel. I know kernel config can be boring, but I'm hoping someone will have an impressive answer.

For me I have a very lightweight kernel that runs wayland on nvidia without any issues to date.

Hows the perf in the VM?

Amazing, basically native speeds,
currently playing Horizon Forbidden West with maxed out graphics and DRS disabled at a steady 60-80 FPS.

Previously I also played Horizon Zero Dawn in it, also maxed out graphics, steady locked 100 FPS,
below is a benchmark comparison of HZD in the Linux host OS and the Windows KVM guest OS:

Has this gotten any easier to do? I set it up a few years ago, it was painful to do and maintain so I let it slide. You were writing all sorts of scripts to specify the passthrough devices and then they'd stop working so you had to track down what was failing and update. Then there was iommu so you had to be careful which groups you added devices to.

Gotta admit, it was very hard to setup initially.
However it's been working perfectly ever since I did.
Been using it for about a year or 2 now.

Also when I linked the Arch wiki,
I noticed in it's article that there's now a gpu-passthrough-manager,
which will likely make the process of setting up a little bit easier.

Amazing. Does Photoshop work ?

Yush, it does under the KVM :)

Is there an easy way to run this for photoshop? GUI if possible

[–] [email protected] 1 points 7 months ago

No easy way to set it up I'm afraid.

But if you're interested,
I posted all the bookmarks I made, with tutorials and tools, when I set mine up here:
