For a GPU configured as passthrough , device plugin does not update the GPU count on the node when a GPU falls off the bus.
To reproduce follow the steps
Remove the GPU from the bus
echo "1" > /sys/bus/pci/devices/<gpu_pci_id>/removeValidated the GPU is no longer visible from the host using lspci
lspci -nnk -d 10de:The number of GPUs exposed on k8s node doesn't change.
Watching for iommu groups under
/dev/vfiocreates a fsnotify when the GPU falls off the bus
