STRUCT PWRSEQ_DESC(9)

💅 struct pwrseq_desc(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for struct pwrseq_desc, and it's genuinely such a clean little design. What it does? It wraps access to the pwrseq_device and makes sure that one user can't break the reference counting for everybody else. like, it's the responsible friend holding the group's stuff so nobody double-frees the vibes 💖

✨ NAME ✨

struct pwrseq_desc — wraps access to the pwrseq_device and ensures that one user cannot break the reference counting for others. no cap, that's the whole job and it does it flawlessly 🫶

🦋 SYNOPSIS 🦋

struct pwrseq_desc {
    struct pwrseq_device *pwrseq;
    struct pwrseq_target *target;
    bool powered_on;
 };

🎀 Members 🎀

• pwrseq — the reference to the power sequencing device itself. your main character pointer, honestly 💅
• target — a reference to the target that this descriptor allows you to control. it's giving "this is my lane" energy ✨
• powered_on — the power state set by the holder of the descriptor. and bestie, read this carefully: it does not necessarily correspond to the actual power state of the device. it's what you said, not what the hardware's doing 🙈

aaaand that's the whole page, bestie — short, sweet, and iconic 👑 this came out of ./drivers/power/sequencing in October 2026, so like… remember that date for the exam 💀 ily, go read pwrseq_get(9) next 🍓💜
