pci_dev_complete_resume(9)

💅 pci_dev_complete_resume — like, the Kernel API Manual page, bestie ✨

okay so this is pci_dev_complete_resume(9) from the Kernel API Manual, and honestly? she's a lil one-function wonder and I'm obsessed 🎀

---

🌸 NAME 🌸

pci_dev_complete_resume — Finalize resume from system sleep for a device. that's it. that's the whole job. iconic behavior fr 💖

---

✨ SYNOPSIS ✨

void pci_dev_complete_resume (struct pci_dev *pci_dev );

periodt. no return value, no drama, just vibes and a pointer 💅

---

🦋 ARGUMENTS 🦋

• pci_dev — Device to handle. that's the one, that's the device you're handling, she's the main character here 👑

---

🌈 DESCRIPTION 🌈

okay so here's the tea 🍓 — if the device is runtime suspended and it's wakeup-capable, you enable PME for it.

and why, you ask? because PME might have been disabled during the prepare phase of system suspend — specifically if the device was not configured for system wakeup at that point. so we're putting it back, no cap 😭✨

it's giving "cleanup era" and honestly good for her.

💜 SEE ALSO 💜

bestie. buckle up. the SEE ALSO section is LONG long, like a group chat that never sleeps 💀 the kernel file lives at ./drivers/pci/pci.c, and here's every single sibling in the family — all of them, no skips, no cuts 🫶

🧚 lil reminder bestie: everything above is straight from the source — don't invent behavior, just call the function and let the kernel do her thing 💖

and that's a wrap, bestie 🎀 this page lives in ./drivers/pci, dated October 2026, and it's filed under pci_dev_complete_resume(9) — go forth and resume, you've got this ⭐🌈💜
