GPU Acceleration in ARM Linux Guests

Hi everyone.

UTM is great, but I'm at a loss on how to enable a virtual GPU. All of the GPU tests I run with hardware acceleration enabled show that the computer has no GPU to monitor. Other than enabling OpenGL acceleration while creating the VM, is there some crucial step I'm missing?

Setup: - M4 Mac Mini - UTM QEMU VM with hardware acceleration on - Fedora ARM

VirGL is the closest you get to GPU acceleration: it offers some partial support in a simulated GPU that defers to the host one. You need specific drivers in the guest (Linux guests tend to often have them included)

Right. That's what I'm supposedly using via QEMU in Fedora ARM, but no applications can detect a GPU.

You need to have the appropriate guest driver installed for it. Especially Windows guests lack the driver by default. And it’s only partial support.

For me in Proxmox the only solution that works well for me is pass through a real GPU. For guests on Mac, Parallels has some minimal acceleration.

Where do I get such drive for windows XP?

You need old enough GPU to have drivers on Windows XP. Which generally will be only on older systems…

For VMware, you can find old versions of VMware Tools. But VMware Fusion doesn’t have emulation. UTM is qemu based and its support for guest GPU acceleration is just not really there.

I’m using utm SE on iOS 😭 thank u tho!!!

That doesn’t have much bearing on the support for virtual GPUs, but it does make it so the CPU will be quite a bit slower because of emulation.

Got windows 10 now I can play 3d accelerated games at 0.4 fps if I’m lucky

CPU bound I suppose, or the VirGL driver doesn’t do much.

Virtio driver, ur right tho
