Execution engine review: this one is long because ELF loading, WASM runtime behavior, binary loading, JIT paths, traps, and portability can introduce a lot of subtle kernel bugs.

This post looks at what still needs to be implemented before the execution engine should be pushed through the final dev cycle, after the architecture and abstraction layer.

How do you handle portability testing near the end of an OS dev cycle?

Launching my blog with a walkthrough of virtme-ng: boot your kernel in QEMU, try cross-arch builds, run kselftests, and offload compilation to a remote machine. I'll be using virtme-ng on future posts.

A recent LKML patch used a tool called kconfirm to find Kconfig "dead code." The tool is so obscure that even Andrew Morton was puzzled, replying:

"OK, I give up. Where do I learn about kconfirm?"

It’s refreshing to see the person overseeing the kernel’s most critical code have a "no idea what this is" moment! Like Andrew, I’m dying to know—where DO we learn about this? Haha! 😂
