Thread 106588757

What's your opinion on VFIO/GPU passthrough? What are the benefits for you?

For me, it allows me to try a new OS as if it was bare metal.

>>106588757 (OP)
Are you using two separate gpus or doing a single passthrough?

>>106588757 (OP)
total miku love
total nvidia death (no sr-iov on consumer gpus)

Single. Will get a second GPU soon.

>>106588757 (OP)
VFIO lets me run Windows and still have some Linux utility on the side that would have been disallowed or needlessly complicated by the malicious retards working at Microsoft.
>>106589277
It's unfortunate that no one else is really picking up the slack properly.
AMD keeps releasing special snowflakes that need special configuration and Intel is dragging their feet.
Some Nvidia consumer GPUs can technically do sr-iov (vgpu-unlock), but then you'd still need to fuck with their enterprise drivers.

>>106591066
That's rough how though

>>106591503
Not really rough. Just making do with whatever I have rn. Plus it pushes me to use the VM.

>>106588757 (OP)
I used to run it but its just incredibly janky and fragile. gaming on linux is good enough now so I just got an AMD GPU, I dual boot if a game doesnt work. this is more comfy anyway because I get to use windows less

iv been roll playing as a boomer going into threads and screaming WAT! at people. they seem to think i want more information instead of just being deaf.

>>106592176
I agree. I have Nvidia Cheetos RTX 4060, yet games nice on Linux. I did VFIO to try Windows Server 2022. I also noticed that Linux Mint boots fine with secure boot on, even with Nvidia (open) drivers. Idk if Xorg werkz.

literally only intel provides sr-iov on igpus, at least passthrough works flawlessly on nvidia, unlike AMD.

>>106592483
OP here. I didn't do SR-IOV. Just used a script from GitHub to do GPU passthrough (admittedly though, I did change some stuff in the script)

>>106591450
Because it an enterprise-tier feature you dingus. It is artificially segmented. How else AMD and Nvidia are going to justify the premiums on their professional tier graphics SKUs?

>>106591918
How are you doing that

>>106588757 (OP)
I only have one GPU in my computer, and I want both OSs to be functional at the same time.
Messing with VMs is the only time I regret not going with a CPU with an iGPU.

>>106593082
depends how you define "functional". i've done single-gpu passthrough before (before i got another gpu). you can do it. it does mean completely unloading the gpu from linux before starting the vm. you can still access the linux host from the windows vm in other ways though, namely via ssh or vnc, it just won't have a gpu attached to it

It's great for gaymen. Otherwise I don't need it.

>>106593082
You could in theory expose a virtual display over rdp or vnc for example. Of course its software rendered, but it should still be usable if you're just looking to quickly access some programs or files on your host machine, assuming tty isn't enough.

I couldn't figure out how to set it up desu. I wanted to pass the igpu into the vm and leave the dedicated for the host but I couldn't figure it out on qemu

>>106588757 (OP)
i could never make it work on a ryzen igpu and nvidia gpu laptop

>>106594988
Passing the iGPU can be harder because it's not really an independent PCIe device. This is or used to be the case for Intel, at least.
>>106595842
This can also be tricky, especially if the GPU doesn't have its own video outputs. Nvidia started supporting it officially a few years ago. If it was a driver issue maybe try again.

>>106588757 (OP)
I set it up a long time ago back when it was the hot meme. I thought it was pretty clunky on its own, and barely an improvement over dual-booting unless you were just a schizo who didn't like the idea of Windows running on bare metal. The Looking Glass project was very promising, but it had a lot of limitations last time I used it (bandwidth constraints, needing a spare/dummy display output to work).

Doesn't really seem worth it for gaming anymore, now that pretty much everything runs on Linux through Proton (except for multiplayer games which also ban people for playing through VMs anyway).

>>106596326
I have dual boot too (Windows 11 instead of Server 2022). I play Valorant (shocker I know) every friday and saturday. I too play on Proton (other games).

>>106593025
There's a script that kills display manager and binds the gpu to VM. When you shut the VM down, the gpu binds back to host and starts the display manager.
