💖 pci_target_state(9) 💖

okay bestie, we’re in the Kernel API Manual, and this page is pci_target_state(9) — the function that finds an appropriate low power state for a given PCI dev. It’s giving “pick the right nap mode” energy, no cap. ✨

🌸 NAME 🌸

pci_target_state — find an appropriate low power state for a given PCI dev. That’s the whole assignment, and it ate. 💅

✨ SYNOPSIS ✨

pci_power_t pci_target_state (struct pci_dev *dev , bool wakeup );

🎀 ARGUMENTS 🎀

okay so there are two inputs, bestie:

  • dev — the PCI device. Literally the device in question. 🫶
  • wakeup — tells the function whether or not wakeup functionality will be enabled for the device. Important vibe check, fr fr.

🦋 DESCRIPTION 🦋

Here’s the tea ☕: this function uses underlying platform code to find a supported low power state for dev. It’s not out here freelancing — it’s relying on the platform, iykyk.

If the platform can’t manage dev, it returns the deepest state from which it can generate wake events, based on any available PME info. That part matters, bestie: deepest state, wake events, available PME info. Periodt. 🌈
