What is yocto-kernel-bsp?

A documentation-first guide for Yocto Linux kernel and BSP work. Yocto is a system for building customized Linux distributions, and a BSP contains hardware-specific support.

It is for integrating vendor kernels, changing kernel configuration, editing device trees and machine settings, resolving boot handoffs, and building or deploying kernel changes.

It helps agents edit the correct machine settings, kernel recipes, configuration files, device trees, and BSP layers while checking the result with BitBake.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00093	$0.00577
Opus 5.5	$0.00037	$0.00231
Sonnet 5.5	$0.00019	$0.00115
Haiku 4.5	$0.00009	$0.00058

Security

Grade A, and why

yocto-kernel-bsp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/yocto_kernel_doc_router.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Yocto Kernel BSP

Core Workflow

Identify the Yocto release, MACHINE, BSP layer, kernel provider, and kernel recipe before editing.
Inspect existing machine configuration, kernel recipe, .bbappend, device tree, defconfig, and config fragments.
Prefer the product BSP layer for local changes. Avoid editing upstream poky, meta, meta-yocto, OE-Core, or vendor layers unless preparing an upstreamable patch.
Separate concerns:
- Machine selection belongs in conf/machine/*.conf.
- Kernel source/provider policy belongs in distro or machine config only when locally justified.
- Kernel config belongs in fragments or defconfig according to the project's existing style.
- Device tree changes belong near existing DTS/DTSI structure or in a layer-local patch.
Validate with BitBake and kernel tasks before claiming success.

Commands

bitbake-layers show-recipes virtual/kernel
bitbake-layers show-appends
bitbake -e virtual/kernel
bitbake virtual/kernel
bitbake -c menuconfig virtual/kernel
bitbake -c diffconfig virtual/kernel
bitbake -c deploy virtual/kernel

Use yocto_kernel_doc_router.py with a topic name for official documentation links.

device-tree-checklist.md: DTB selection, DTS/DTSI origin, patch workflow, and deploy checks.
machine-config-checklist.md: machine variables, provider policy, overrides, and board variants.

Guardrails

Do not assume linux-yocto behavior applies to vendor kernels without checking the recipe/classes.
Do not mix board variants that have different RAM, boot media, storage, or DTBs.
Do not change PREFERRED_PROVIDER_virtual/kernel, KERNEL_DEVICETREE, or COMPATIBLE_MACHINE globally unless the blast radius is understood.
Do not hand-edit generated kernel build output as a permanent fix; add patches, fragments, or metadata in the owning layer.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
