Hi!

I am trying to get L40S GPUs working on Proxmox 8. While they are working fine as passthrough, I would like vGPU support.

I think I am 90% there, and that the last piece in the puzzle is setting up the actual vGPU profiles using code similar to your vgpu_unlock_hooks.c | static vgpu_unlock_vgpu_t vgpu_unlock_vgpu[] function.

Using /usr/share/nvidia/vgpu/vgpuConfig.xml, I am able to find the dev_id and subsys_id. I can add the following line to the function:

VGPU(0x26b9, 0x188d, "NVIDIA L40S-2Q"),

and to vgpu_unlock_pci_devid_to_vgpu_capable I add:

	/* L40S */
	case 0x2601 ... 0x271D: 
		return 0x26b9; /* L40S */
	}

However, this does still result (after cargo build and reboot) in

root@pve:~# mdevctl types

root@pve:~# 

I think I did all the other steps correctly. Do I have to add additional lines to the vgpu_unlock_hooks code?
