TL;DR: KernelCI must be configured for CIP SLTS so a new board, its compatible strings, and the matching scheduler and platform entries line up before automated boot testing can run on the intended device profile, according to Cybertrust Japan. The core issue is governance of test infrastructure and metadata, because mismatched platform definitions break coverage and weaken release confidence.

Key questions
Q: Why do KernelCI tests fail when board metadata and lab setup drift apart?
A: KernelCI depends on the platform definition, scheduler entry, and lab target all describing the same board.
Q: How should teams govern new board onboarding in KernelCI?
A: Treat board onboarding as a controlled configuration change.
Q: What breaks when a KernelCI platform is defined but never scheduled?
A: You get apparent coverage without executed coverage.
Practitioner guidance
- Audit board-to-lab mapping before enabling a new device Confirm that the platforms.yaml entry, compatible strings, and connected lava target all point to the same hardware profile before scheduling tests.
- Validate scheduler routing for every new KernelCI job Check that the job entry, runtime selection, and platform list produce a runnable path rather than a defined but inactive configuration.
- Compare extracted compatible strings with kernel source Use the compatible extraction workflow to verify that the platform definition matches the board files in the kernel tree you plan to test.
Bottom line: KernelCI board onboarding is a governance exercise as much as a build task, because the platform definition must match the lab target for results to mean anything.

Configuration integrity is the real control here: KernelCI board enablement only works when metadata, scheduler logic, and lab execution describe the same asset. A device profile that is technically valid but operationally mismatched creates coverage theatre, where tests appear to run but no longer validate the intended hardware. Practitioners should treat this as a control integrity problem, not a documentation task.
A question worth separating out:
Q: What is the difference between KernelCI platform metadata and scheduler configuration?
A: Platform metadata describes the device identity and compatibility, while scheduler configuration decides when and where the test runs. Both are required: one names the target, the other makes execution happen. If either side is wrong, automated validation loses reliability.
