How about retry if get empty pci id.
For example:
lspci -nn | grep " VGA.*Gen .* Graphics" -i | grep "\[8086:.*\]" -o | awk -F :
'{print $2}' | awk -F ] '{print $1}'
if [ -z "$1" ]; then
lspci -nn | grep " VGA.*Intel .* Graphics" -i | grep "\[8086:.*\]" -o | awk
-F : '{print $2}' | awk -F ] '{print $1}'
fi
if [ -z "$1" ]; then
lspci -nn | grep " VGA.* Graphics.*8086" -i | grep "\[8086:.*\]" -o | awk -F
: '{print $2}' | awk -F ] '{print $1}'
fi

Subject: Re: [Beignet] [PATCH V2] gbe_bin_generater: fix two bugs.
Some PCI ID do not have Gen keyword, such as ruiling's IVBridge XXXXXX So need
to refine the command line
