How to identify individual GPUs in Linux

[CCaves]

I am trying to figure out a way to identify individual GPUs on a linux system. From what I understand I should be able to do this using atiflash -isr should allow me to do this easily. However, the command doesn't seem to work, I am not sure if I am misinterpreting the command or if it is simply no longer supported or what's going on.

Anyone got any suggestions?

looking through dmesg should give you the ability to see something identifying. "dmesg | grep nvidia" or amd should work. Otherwise if they are nvidia cards with Nvidia drivers nvidia-smi will work.

I tried dmesg and couldn't find anything that was unique other than PCIE slots. Perhaps I should have been more clear, I am trying to give each GPU a unique ID so I can track them through a large system. For instance, I need to be able to track them when I move them between motherboards etc.

What linux are you using?

ubuntu

ubuntu

That's good to know, I usually at work deals with Centos and FreeBSD at work, but try: lspci | grep -E 'VGA|Display' or lspci -nn |egrep "VGA|Display" in the terminal that should be enough.

If you want to use dmesg like @therealmeep says I think it's dmesg |grep -i agp not a 110% sure if I am way off haven't used Ubuntu for years I am usually a Windows person

As I don't have access right now (Thanksgiving) I will try that and reply asap. Just for the record what would I be looking for? Will this give me access to the SN or something?

lspci | grep -E 'VGA|Display' should show info like this: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP] (This is just an example)

lspci -nn |egrep "VGA|Display" should show info like this: 00:02.0 VGA compatible controller [0300]: Intel Corporation 4 Series Chipset Integrated Graphics Controller [8086:2e32] (rev 03) (This is just an example)

They should both be listing all the graphic cards installed in the pc if this doesn't work what about lspci | grep VGA this should just list the gpu model. Again sorry if I am wrong I do not have Ubuntu and I am a Windows person but I do pick up things and remember them when I need them

Ok, I suspect you might be misunderstanding what I am asking.

I need a way to track individual GPUs through a large system many of which are the same make and model. Thus what I need is a unique identifier for each GPU such as a serial number or Mac Address. This is why I started with the -isr command in atiflash. That said the number given by ispci -nn |egrep (8086:2e32), I am assuming that this is not a Serial Number but rather a BIOS hash or something since that is what it is with dmesg | grep amd which is what I have already tried. Correct me if I am wrong?
