pci_enable_wake(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so this is pci_enable_wake(9) from the Kernel API Manual — the function that changes wakeup settings for a PCI device ✨ bestie it literally just flips the "can this device wake me up" switch, no cap.

✨ SYNOPSIS ✨

int pci_enable_wake (struct pci_dev *pci_dev , pci_power_t state , bool
enable );

🎀 ARGUMENTS 🎀

  • pci_dev — the target device 💖 like, the actual piece of hardware we're talking about here.
  • state — the PCI state from which the device will issue wakeup events 🌸 so, which power state it's waking up from.
  • enable — whether or not to enable event generation ⭐ on or off, yes or no, the whole vibe check.

🦋 DESCRIPTION 🦋

so here's the tea ☕ — if enable is set, the function checks device_may_wakeup for the device before calling __pci_enable_wake for it. that's it, that's the whole move. it's giving gatekeeper energy and honestly? correct of it 💅

no cap though, that conditional is the entire behaviour described here — enable on = check first, then call. don't go adding lore that isn't in the source 🫶

🔥 SEE ALSO 🔥

Kernel file ./drivers/pci/pci.c — and like, an absolutely iconic amount of friends, bestie. we're talking main-character-adjacent at minimum, so buckle in 🎀

and that's the whole page bestie 🧚💜 source is ./drivers/pci, dated October 2026, living down there in the footer next to pci_enable_wake(9) — slay, go set some wakeup settings 💅⭐
