💅 zpci_scan_configured_device(9) 💅

okay bestie, welcome to the Kernel API Manual — this one is all about scanning a freshly configured zpci_dev, and yes it is giving low-level PCI energy ✨

🌸 NAME 🌸

zpci_scan_configured_device — scan a freshly configured zpci_dev 🫶

---

🛠️ SYNOPSIS 🛠️

int zpci_scan_configured_device (struct zpci_dev *zdev , u32 fh );

---

🎀 ARGUMENTS 🎀

• zdev — the zpci_dev to be configured, aka the main character of this function 💖
• fh — the general function handle supplied by the platform 🌟

---

🦋 DESCRIPTION 🦋

so basically: given a device in the configuration state Configured, this function enables it, scans it, and adds it to the common code PCI subsystem if possible. slay 💅

but bestie, listen — if any failure occurs, the zpci_dev is left disabled. no cap, that part matters 😭

fr fr: failure means the device stays disabled, so don’t expect it to magically show up all enabled and iconic.

⭐ RETURN ⭐

• 0 on success 🎉
• or an error code otherwise 🙈
