How can I make a lock free queue without OS support, ESP32?

I'd ask your friendly neighborhood LLM for design advice, but off the top of my head, so long as `static_assert(std::atomic<whatever>::is_lock_free)` passes, you could build a lock-free SPSC queue with just plain ol' std::atomics and probably liberal use of `alignas()` calls

  • Most local LLMs I've used are not particularly great with the advice unfortunately, probably because I haven't spent thousands of dollars on new hardware recently

    • Edited my comment for clarity. I meant "friendly local" as a euphemism, like "neighborhood pub".

      Anyways. Ask Claude.
