Wrong GPU info after upgrading from 0.12.0 to 0.16.0

[atosahatos]

Hello,

I have the following code to get GPU info and print all detected cards:

func detectGPU() error {
	gpu, err := ghw.GPU()
	if err != nil {
		fmt.Printf("Error getting GPU info: %s\n", err)
		return err
	}
	for _, card := range gpu.GraphicsCards {
		fmt.Println("Card:", card)
	}
}

On the same hardware (containing 2 NVIDIA cards) with the different versions of GHW I got the following outputs.

0.13.0:
Card: card #0 [affined to NUMA node 0]@0000:01:00.1 -> driver: 'mgag200' class: 'Display controller' vendor: 'Matrox Electronics Systems Ltd.' product: 'MGA G200eH3'
Card: card #1 [affined to NUMA node 0]@0000:26:00.0 -> driver: 'nvidia' class: 'Display controller' vendor: 'NVIDIA Corporation' product: 'GA102GL [RTX A5000]'
Card: card #2 [affined to NUMA node 1]@0000:8a:00.0 -> driver: 'nvidia' class: 'Display controller' vendor: 'NVIDIA Corporation' product: 'GA102GL [RTX A5000]'

0.14.0:
Card: card #0 [affined to NUMA node 0]@0000:01:00.1 -> driver: 'mgag200' class: 'Display controller' vendor: 'Matrox Electronics Systems Ltd.' product: 'MGA G200eH3'
Card: card #1 [affined to NUMA node 0]@0000:25:01.0 -> driver: 'pcieport' class: 'Bridge' vendor: 'Intel Corporation' product: 'unknown'
Card: card #2 [affined to NUMA node 1]@0000:89:01.0 -> driver: 'pcieport' class: 'Bridge' vendor: 'Intel Corporation' product: 'unknown'

0.15.0 and 0.16.0:
Card: card #0 [affined to NUMA node 0]@0000:01:00.1 -> driver: 'mgag200' class: 'Display controller' vendor: 'Matrox Electronics Systems Ltd.' product: 'MGA G200eH3'
Card: card #1 [affined to NUMA node 0]@0000:26:00.0 -> driver: 'nvidia' class: 'Display controller' vendor: 'NVIDIA Corporation' product: 'GA102GL [RTX A5000]'
Card: card #2 [affined to NUMA node 1]@0000:89:01.0 -> driver: 'pcieport' class: 'Bridge' vendor: 'Intel Corporation' product: 'unknown'

It seems 0.13.0 returned the correct info.
In 0.14.0 the returned information is wrong for both cards.
In 0.15.0 and 0.16.0 GHW gives a mixed result for the two cards.

Thank you for any help / fix on this problem.

Thank you for the bug report @atosahatos! I will look into this as soon as possible (currently out in London for KubeConEU so might be a bit before I can get to this)

Please confirm that you on a Linux system and if you wouldn't mind, please paste the output of the following:

lsb_release -a
uname -r
ls -al /sys/class/drm/card[0-2]

Yes, this is SLES 15.6:
