ENUM UFSHCD_PMC_POLICY(9)

💅 enum ufshcd_pmc_policy(9) — the Kernel API Manual, bestie edition 🦋

Okay so this is a page straight out of the Kernel API Manual, and it's about enum ufshcd_pmc_policy — that's the Power Mode change policy situation. Yes, that's literally what the NAME section says, and no, I'm not going to pretend it's more complicated than that. It's an enum. It has two (2) members. It's giving minimal icon energy and honestly? Obsessed. ✨

🌸 NAME 🌸

enum ufshcd_pmc_policy — Power Mode change policy. That's the whole name, that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

Here's the shape of it, copied exactly so you can trust me fr fr:

enum ufshcd_pmc_policy {
    UFSHCD_PMC_POLICY_DONT_FORCE ,
    UFSHCD_PMC_POLICY_FORCE

};

Two constants, that's it, that's the lineup. 👑

🧚 Constants 🧚

• UFSHCD_PMC_POLICY_DONT_FORCE — Do not force a Power Mode change.</> Like, chill. Sit in whatever Power Mode you're already in. No pushing, no shoving, no drama. 🙈
• UFSHCD_PMC_POLICY_FORCE — Force a Power Mode change</> — and yes, even if the current Power Mode is the same as the target Power Mode. Same destination, still making the trip. Main character energy only. 💅🔥

Bestie note: the "even if it's the same" part is the whole point of FORCE. Don't skip it. That's the detail. 🫶
