This looks like a lot of heavily LLM-assisted effort. Please review the relevant documentation, starting here: https://docs.kernel.org/process/submitting-patches.html#using-assisted-by I feel the testing strategy is pretty questionable. Any invariant violation is possible with that type of meddling. I was interested in whether you drove the interrupt sequence via emulated hardware. I asked because upstream qemu doesn't currently support the snoop device. In v3 you said: The issue was observed on physical AST2600 (dual-core Cortex-A7) in production under heavy POST code traffic during concurrent userspace reads. https://lore.kernel.org/all/[email protected]/ Is this true? What platform did you test with? Andrew
