💅 struct powercap_zone_constraint — Kernel API Manual, bestie edition ✨

okay so real talk, this is a page from the Kernel API Manual and it's genuinely short and sweet — it's just describing one lil struct. no cap, we can absolutely get this. 🫶

🌸 NAME 🌸

struct powercap_zone_constraint — Defines instance of a constraint

like, that's it, that's the whole name section. she's concise. she's iconic. periodt. 💅

✨ SYNOPSIS ✨

struct powercap_zone_constraint {
    int id;
    struct powercap_zone *power_zone;
    const struct powercap_zone_constraint_ops *ops;
 };

that's the whole shape of her, bestie. three members, no drama. 🎀

🧚 Members 🧚

• id — Instance Id of this constraint. yes literally just the number that tells you which constraint you're looking at. iykyk. ⭐
• power_zone — Pointer to the power zone for this constraint. so like, this constraint's home base, fr fr. 🏠
• ops — Pointer to the constraint callbacks. this is where the function pointers live and honestly that's the whole personality of this struct. 🔥

This defines a constraint instance.

that's the entire description. no lore, no backstory, no tragic third act — it defines a constraint instance and it's at peace with that. honestly? main character energy. 👑

lowkey a reminder: everything here came straight from ./include/linux and it's dated October 2026 — so when you cite this in your head, that's the vibe check. 🌸

okay bye bestie, go write some constraints, you're gonna slay 💜🦋🎀
