The Kubernetes add-on Node Feature Discovery is enhanced with a new coprocessor feature and support for detecting the NX-GZIP on Power 10. This work supports the use of libnxz/power-gzip feature.
We setup Kubernetes 1.25 on a Power10 RHEL 9.1 PowerVM. We built the feature and submitted the PR on behalf of IBM. You’ll need RHEL 9.1 as an operating system on Power 10.
When the Worker or Control Plane node has Node Feature Discovery enabled on a Power 10 PowerVM with Red Hat Enterprise Linux 9.1 or higher, the label coprocessor.nx_gzip is present on the node. You can see more details in the PR 956
