ENUM DIM_STATE(9)

💅 enum dim_state — the DIM algorithm states, bestie

okay so this is enum dim_state(9) from the Kernel API Manual and honestly? it's giving state-machine realness. it's a tiny enum, it's iconic, it tells the DIM algorithm whether it's valid to start an iteration. periodt. ✨

---

🌸 SYNOPSIS 🌸

enum dim_state {
    DIM_START_MEASURE ,
    DIM_MEASURE_IN_PROGRESS ,
    DIM_APPLY_NEW_PROFILE

};

three constants, no cap. let's meet them 🫶

---

🎀 Constants 🎀

• DIM_START_MEASURE — this is the first iteration. that's it, that's the vibe. also the state you land in after applying a new profile, so it's lowkey the "fresh start" era 💖
• DIM_MEASURE_IN_PROGRESS — the algorithm is already in progress, bestie. so check if you need to perform an action. don't just barge in 🙈
• DIM_APPLY_NEW_PROFILE — the DIM consumer is currently applying a profile, so there is literally no need to measure rn. read the room 💀

---

✨ Description ✨

these states determine if the algorithm is in a valid state to start an iteration. that's the whole gig. vibe check, then iterate 🌈

okay bye ily, this page lives in ./include/linux, dated October 2026, and it's part of the Kernel API Manual — mwah, slay, see you in the next manpage 💜🎀
