pcie_pme_mark_devices(9)

🎀 pcie_pme_mark_devices — the Kernel API Manual page, bestie 🎀

Okay so this is the pcie_pme_mark_devices(9) page, and it’s basically about giving devices below a PCIe port their little “yes, I can wake things up at run-time” flag. Slay.

---

✨ NAME ✨

pcie_pme_mark_devices — set the wakeup flag for devices below a port. No cap, that’s the whole vibe.

---

🌸 SYNOPSIS 🌸

void pcie_pme_mark_devices (struct pci_dev *port );

---

🦋 ARGUMENTS 🦋

• port — the PCIe root port or event collector to handle. That’s the main character here.

---

💖 DESCRIPTION 💖

For each device below the given root port — and yes, including the port itself — this sets the flag that says it can signal run-time wake-up events.

If port is a root complex event collector, then it does this for each root complex integrated endpoint instead. Periodt.
