Add a label for CPU Manufacturer/Name

[zbintliff]

Tell us about your request

Similar to how you provide karpenter.k8s.aws/instance-gpu-manufacturer it would be great to have one for CPU manufacterer. We have a use case where workloads are using intel specific features and want to target i nodes vs a nodes. Right now the labels show they are just arch amd64 for both, which means we need to define specific instance types and update them as new generations come out.

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?

We have come workloads that only want to go on intel based instances. Right now we have our own metadata to add this type of information but would be great if it was "free".

Are you currently working around this issue?

During startup we parse the output of lscpu to determine amd vs intel

Although Karpenter could do the labelling, you could also have a Provisioner with an allow list of instance types (which is already supported) and then use node feature discovery to add the labels you want.
