Provide Neuron kmods by piyush-jena · Pull Request #407 · bottlerocket-os/bottlerocket-kernel-kit

piyush-jena · 2026-04-16T01:15:03Z

Description of changes:
This series of changes provides the neuron driver as a standalone kmod package. We are doing this to ensure that the kernel module compilation does not accidentally interfere with or modify the existing kernel build artifacts.

Testing done:

Both x86_64 and aarch64 hosts boot
Tested inf1 and inf2 instance with each kind of kernel and made sure the driver was loaded

^ Force pushes fixes the following:

I had removed latest-kernel-srpm-url.sh for in kernel-6.1 by mistake. I put it back.
I had forgotten removing the references for neuron kmods in Cargo.toml in kernel-6.1. I removed them.

piyush-jena · 2026-04-23T20:56:08Z

^ The force push above addresses the following:

Separate out the leftover EFA related CMakeLists to a separate commit
Add additional kmods - separate latest, inf1 and extras package. This will allow us to have correct versioning in the RPM packages.
Add end of support BRSA for kernel-{kmajor}-modules-neuron because we will no longer be shipping that sub-package.
