dev_pm_skip_resume(9)

🌸 dev_pm_skip_resume(9) 🌸

okay bestie, welcome to the Kernel API Manual page for dev_pm_skip_resume(9) — like, the actual function, not a vibe. this one's a little optimization check for resuming devices system-wide, and honestly? she's iconic for it 💅

---

✨ NAME ✨

dev_pm_skip_resume — the system-wide device resume optimization check. yep, that's her whole job: deciding whether we can skip the resume for a device. lowkey important 🫶

---

🦋 SYNOPSIS 🦋

bool dev_pm_skip_resume (struct device *dev );

look at that signature. returns a bool, takes a struct device *. clean, simple, slay ✨

---

🎀 ARGUMENTS 🎀

• dev — the target device. like, the one you're asking about. that's it, that's the argument 💖

---

💀 RETURN 💀

so what does she actually hand back? depends on the transition, bestie — three whole cases, fr fr:

• false — returned if the transition under way is RESTORE. no skipping here, nope 🙈
• the return value of dev_pm_skip_suspend — returned if the transition under way is THAW. yes, we're borrowing her answer, iykyk 🔥
• the logical negation of power.must_resume — returned otherwise (that is, when the transition under way is RESUME). so if must_resume says yes, you get false; if it says no, you get true. logical negation, periodt 👑
