you cound introduce accessor macros for nvdev->mem_prop.mem_length and
nvdev->mem_prop.hpa

Accessors are not the usual style..

I meant something like

  #define nvgpu_mem_size(nvdev) (nvdev)->mem_prop.mem_length
  #define nvgpu_mem_pa_base(nvdev) (nvdev)->mem_prop.hpa

This is minor.


+static const struct pci_device_id nvgpu_vfio_pci_table[] = {
+	{ PCI_DRIVER_OVERRIDE_DEVICE_VFIO(PCI_VENDOR_ID_NVIDIA, 0x2342) },

It would be good to add definitions for the PCI IDs.

The common form these days is to have a comment with the marketing
name, we stopped putting constants for every device a while ago.

OK then.

Thanks,
