[BUG] 'salt-call grains.item gpus:vendor' lists only a single GPU vendor

[rjc]

Description

All GPU vendors and GPU model names are visible when running:

# salt-call grains.item gpus
local:
    ----------
    gpus:
        |_
          ----------
          model:
              G200eR2
          vendor:
              matrox
        |_
          ----------
          model:
              GK110GL [Tesla K20m]
          vendor:
              nvidia

However, only a single one is shown when running:

# salt-call grains.item gpus:vendor
local:
    ----------
    gpus:vendor:
        matrox

On different machines, also with Matrox and Nvidia GPUs, the result will differ and the latter vendor is shown:

# salt-call grains.item gpus:vendor
local:
    ----------
    gpus:vendor:
        nvidia

The results are deterministic insofar as not to flip between vendors on the same machine but I can't seem to find the pattern why on some machines it is one and on other machines the other vendor is shown.

This makes it impossible to target machines using that particular grain, e.g.:

  'gpus:vendor:nvidia':
    - match: grain
    - foo

will only run/apply foo to machines which return nvidia as the first, and only, vendor.

Setup This can be observed without any specific Salt configuration in place.

Please be as specific as possible and give set-up details.

• [x] on-prem machine
• [ ] VM (Virtualbox, KVM, etc. please specify)
• [ ] VM running on a cloud service, please be explicit and add details
• [ ] container (Kubernetes, Docker, containerd, etc. please specify)
• [ ] or a combination, please be explicit
• [ ] jails if it is FreeBSD
• [x] classic packaging
• [ ] onedir packaging
• [ ] used bootstrap to install

Steps to Reproduce the behavior

Run salt-call grains.item gpus:vendor on any machine with GPUs from several vendors.

Expected behavior

Have all vendors returned like so:

# salt-call grains.item gpus:vendor
local:
    ----------
    gpus:vendor:
        - intel
        - matrox
        - nvidia

The same could be extended to gpus:model name:

# salt-call grains.item gpus:model
local:
    ----------
    gpus:model:
        - Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller
        - RV710/M92 [Mobility Radeon HD 4330/4350/4550]
        - GK180GL [Tesla K40c]

[OrangeDog]

Any grain with a list of dicts will have the same behaviour. So does pillar.get and config.get.

I think this has been reported before, but I can't find the issue.

I've run into this same issue. The "Expected Behavior" by @rjc is what I would expect
