Move the previously-protobuf-only internal "feature api" over to the
public "nfd api" package. This is in preparation for introducing a new
CRD API for communicating features.
This patch carries no functional changes. Just moving code around.
Refactor the code, moving the hostpath helper functionality to new
"pkg/utils/hostpath" package. This breaks odd-ish dependency
"pkg/utils" -> "source".
Discover "iommu/intel-iommu/version" sysfs attribute for pci devices.
This information is available for custom label rules.
An example custom rule:
- name: "iommu version rule"
labels:
iommu.version_1: "true"
matchFeatures:
- feature: pci.device
matchExpressions:
"iommu/intel-iommu/version": {op: In, value: ["1:0"]}
Add "iommu_group/type" to the list of PCI device attributes that are
discovered. The value is the raw value from sysfs (i.e DMA, DMA-FQ or
identity).
No built-in (automatic) labels are generated based on this, but, the
attribute is available for custom label rules to use. Examples of custom
rules:
- name: "iommu enabled rule"
labels:
iommu.enabled: "true"
matchFeatures:
- feature: pci.device
matchExpressions:
"iommu_group/type": {op: NotIn, value: ["unknown"]}
- name: "iommu passthrough rule"
labels:
iommu.passthrough: "true"
matchFeatures:
- feature: pci.device
matchExpressions:
"iommu_group/type": {op: In, value: ["identity"]}
Separate feature discovery and creation of feature labels in the pci
source.
Move pci_utils from source/internal to the source/pci package. Change
the implementation of the PciID custom rule to utilize the FeatureSource
interface of the pci source.
Also, add minimalist unit test.
