ENUM V4L2_ASYNC_MATCH_TYPE(9)

📦 version 7.3.1, in nixpkgs unstable

💅 enum v4l2_async_match_type 💅

okay bestie, welcome to the Kernel API Manual — section 9, no less ✨ this one's all about enum v4l2_async_match_type(9) and honestly it's a little icon of a header. it lives in the kernel world and it's not that deep, i promise 🫶

✨ NAME ✨

enum v4l2_async_match_type — it's the type of asynchronous subdevice logic you pick to actually identify a match 💫 like, which algorithm are we using to go "yes, that's the one" 👀

🦋 SYNOPSIS 🦋

enum v4l2_async_match_type {
    V4L2_ASYNC_MATCH_TYPE_I2C ,
    V4L2_ASYNC_MATCH_TYPE_FWNODE

};

that's it. two whole constants. tiny enum, main character energy 👑

🌸 Constants 🌸

  • V4L2_ASYNC_MATCH_TYPE_I2C — the match is gonna check the I2C adapter ID and the address, that's the whole vibe 🔍
  • V4L2_ASYNC_MATCH_TYPE_FWNODE — the match uses a firmware node instead, slay 🧚

💖 Description 💖

so the asynchronous connection logic uses this enum to define the algorithm that gets used to match an asynchronous device. that's literally it, that's the whole job — you're telling it how to match, not what to match 🎀

ngl this is the kind of enum you set once and never think about again, but it's doing important work backstage okay 😭
