pci_pwrctrl_...ce_set_ready(9)

💅 NAME 💅

pci_pwrctrl_device_set_ready — okay so this is the little function that taps the pwrctrl subsystem on the shoulder and is like "bestie, the PCI device is powered-up and ready to be detected" ✨

---

🎀 SYNOPSIS 🎀

int pci_pwrctrl_device_set_ready (struct pci_pwrctrl *pwrctrl );

---

🦋 ARGUMENTS 🦋

• pwrctrl — the PCI power control data, aka the whole vibe of this device's power situation 💜

---

🌸 RETURN 🌸

It hands you back 0 on success, or a negative error number if something went off the rails 😭 (negative = not slaying, basically).

---

⭐ NOTE ⭐

Heads up bestie, this one's important 👑

So like, getting a 0 back does not mean the device was detected. Not even close. It means the bus rescan was successfully started — that's it, that's the whole flex. The device will get bound to its PCI driver asynchronously, so it's giving main character energy doing its own thing on its own timeline, and you just gotta trust the process 🫶
