ENUM DMXDEV_STATE(9)

💜 enum dmxdev_state(9) 💜

okay bestie so this is from the Kernel API Manual and honestly? it's giving "little state machine that could" ✨ we're talking about enum dmxdev_state here, and before you panic — it's literally just a list of vibes a dmxdev filter can be in at any given moment. no cap. 🦋

---

🌸 NAME 🌸

enum dmxdev_state — the state machine for the dmxdev. that's it, that's the whole job. she tracks where a filter is at in its little lifecycle and she does it flawlessly 💅

---

✨ SYNOPSIS ✨

here's the whole enum, looking exactly like this, don't touch:

enum dmxdev_state {
    DMXDEV_STATE_FREE ,
    DMXDEV_STATE_ALLOCATED ,
    DMXDEV_STATE_SET ,
    DMXDEV_STATE_GO ,
    DMXDEV_STATE_DONE ,
    DMXDEV_STATE_TIMEDOUT

};

---

🎀 Constants 🎀

okay so these are the six states and each one is a whole personality, let's go one by one 🫶

• DMXDEV_STATE_FREE — indicates that the filter is freed. she's out, she's done, she's not doing anything rn. free as in free, bestie 💀
• DMXDEV_STATE_ALLOCATED — indicates that the filter was allocated to be used. like she got picked for the group project — reserved and ready, no actual work done yet though 🙈
• DMXDEV_STATE_SET — indicates that the filter parameters are set. the settings are locked in, the configuration is chef's kiss, everything's configured 👑
• DMXDEV_STATE_GO — indicates that the filter is running. she's live, she's working, main character energy fr fr 🔥
• DMXDEV_STATE_DONE — indicates that a packet was already filtered and the filter is now disabled. set only if DMX_ONESHOT. see dmx_sct_filter_params. so like, she did the one thing she was born to do and then immediately retired 😭 iconic behaviour honestly
• DMXDEV_STATE_TIMEDOUT — Indicates a timeout condition. the clock ran out, she waited too long, it's giving "left on read" ⏰💀
