Graphical acceleration in AVF Linux VMs

[NateyB]

I installed an Arch ARM64 VM using the Apple Virtualization Framework. In this case, UTM attaches a VZVirtioGraphicsDeviceConfiguration to the VM.

Graphics work, and I can see from the output of lspci that a VirtIO GPU is attached. I've installed mesa, but glxinfo | grep OpenGL shows that llvmpipe is still being used. Is this because of a lack of driver support on the Linux side for supporting Apple's virtualized GPU?

I took a look at the VirtIO section on GPUs, and it only requires a 2D mode... Do you know of any easy way to query the device for feature bits, to see if VIRTIO_GPU_F_VIRGL is enabled or disabled?

There is no VirGL in Apple's VF. This is something you can file a feedback for with them.
