virtio-gpu-gl-device doesn't boot, and virtio-gpu-gl-pci fails after guest reaches gpu #3084

Describe the issue The newly added GL support in 2.2.2 beta is not working properly. virtio-gpu-gl-device gets stuck at a black screen before even reaching firmware. virtio-gpu-gl-pci runs really slowly, as if each individual GL draw operation is gated by a vsync or flip operation, then eventually errors out when the guest reaches the GPU state. virtio-ramfb seems to run as if its "accelerated" GL is actually a softgpu.

Configuration

UTM Version: 2.2.2
OS Version: macOS Big Sur 11.5.2
Intel or Apple Silicon? Apple Silicon

Crash log Ah, there is a crash: QEMULauncher_2021-09-03-184719_Christophers-Mac-mini.crash.zip QEMULauncher_2021-09-05-134849_Christophers-Mac-mini.crash.zip

Debug log [missing]

Upload VM Here is the config file for the VM: config.plist.zip

@kode54 What are you trying to run? If possible can you upload the .utm?

kode54 commented 3 years ago

Just trying to run Ubuntu Server 21.04 that has been configured to enable ubuntu-desktop. ARM version, on an M1 Mac mini. The problem with the cookie error doesn't happen very often now, but the performance of the virgl is atrocious, getting just over 106fps in non-vsync-constrained glxgears.

osy commented 3 years ago

What do you expect the performance to be? What do you get with QEMU?

kode54 commented 3 years ago

I guess if I want Linux to run with gaming level performance on ARM hardware, I should buy a Linux specific ARM machine.

I could not reproduce a crash, but I do see the slow drawing of the console before graphics mode starts. When I use that display driver it has buttery smooth graphics (I only played a music video, no gaming). Here are some details about my setup. Maybe we can track down differences.

UTM: Version 2.2.4 (36) OS: 11.5.2 (20G95) Apple Silicon

My guest is Debian Buster installed on UTM (not converted from another virtualization program) Now some supporting documentation

Debug log: debug.log

UTM vm config config.plist.txt

I doubt this is a UTM issue though.

kode54 commented 3 years ago

Nope, I've gathered that virgl is not really all that performant. I've found it to actually be less performant at anything GPU heavy than llvmpipe.

I changed my Display to virtio-ramfb and that fixed it.

v 4.1 Updates in the Note Section

Newly created Linux VMs will now use virtio-gpu-gl-pci by default. It is recommended that you change the display card of existing QEMU backend Linux VMs to this card in order to take advantage of the improved renderer backend. This should result in improved performance in GUI rendering. Note that some applications (particularly 3D applications) may lock up or crash UTM and if you are experiencing issues, you can go back to virtio-ramfb or virtio-vga.
