Kernel and embedded Linux engineers often need to reproduce a build or test from someone else. In practice this is still harder than it should be.
A kernel may be built with one toolchain. The rootfs may come from a local build. Firmware may have changed. A model may need specific variables. Continuous Integration (CI) and lab runs may hide setup steps in scripts or jobs.
Then someone asks:
Can I reproduce this?
Too often the answer is: not easily.
This talk shows a practical way to make this better with modern open source tooling, and to show useful workflows that kernel and embedded engineers may not know about yet.
We show how to build the kernel in a repeatable way, provide a known rootfs, boot the target, run tests, and collect logs.
Then we use two Arm examples. One is an OP-TEE flow, where TF-A, U-Boot, and OP-TEE are part of the setup. The other is a CCA flow on QEMU-arm64 and FVP-aemva, where the model setup and software stack also matter.
We use open source tools from the TuxSuite ecosystem, but the focus is the workflow. The same workflow can run on a laptop, in CI, in lab infrastructure, or at scale.
Anders Roxell is a Linux kernel engineer at Linaro, focused on testing and platform validation. He's a KernelCI and TuxSuite contributor, and works currently on the Linux kernel builds and tests workflows.
