I'm not sure, I'm hoping I might be pointing the devs in the right direction

I'm not sure if drmGetDeviceNameFromFd vs drmGetDeviceNameFromFd2 could cause
the issue too - I think it might

I found in the xserver:

hw/xfree86/dri2/dri2.c:    if (drmGetDevice(info->fd, &dev) || dev->bustype !=
DRM_BUS_PCI) {
hw/xfree86/drivers/modesetting/dri2.c:    info.deviceName =
drmGetDeviceNameFromFd(ms->fd);

drm/xf86drm.c:int drmGetDevices(drmDevicePtr devices[], int max_devices)

In the AMDGPU DDX:

src/amdgpu_dri2.c:      info->dri2.device_name =
drmGetDeviceNameFromFd(pAMDGPUEnt->fd);

And in libva:

va/drm/va_drm_utils.c:    name = drmGetDeviceNameFromFd(fd);

I notice in the old libva1 code there was no drmGetDevice stuff and it's only
in libva2 I could find the above reference
