psp_dev_create(9)

💅 psp_dev_create(9) — like, the Kernel API Manual, but make it make sense

okay so bestie, welcome to psp_dev_create from the Kernel API Manual ✨ this is the little function that literally births a PSP device and gets it registered — main character energy from the very first line, no cap 🎀

---

🌸 NAME 🌸

psp_dev_create — create and register a PSP device 🦋 (yes, that's the whole vibe: you make it, and it goes live)

---

✨ SYNOPSIS ✨

struct psp_dev * psp_dev_create (struct net_device *netdev , struct
psp_dev_ops *psd_ops , struct psp_dev_caps *psd_caps , void *priv_ptr );

so you call it and it hands you back a struct psp_dev * — that's it, that's the whole flex 💅

---

🫶 ARGUMENTS 🫶

four things, bestie, and each one matters, ok? don't skip any of them, this is not a vibe check you wanna fail 😭

• netdev — the main netdevice 👑 like, the actual netdev this whole party is attached to.
• psd_ops — the driver callbacks 🌈 your driver's little stack of "here's what to do when X happens" functions.
• psd_caps — the device capabilities ⭐ all the things this device can actually do. brag about it, it's allowed.
• priv_ptr — a back-pointer to the driver's private data 🔥 your own little stash of stuff, kept safe and pointed at.

---

💖 RETURN 💖

it returns a pointer to the allocated PSP device 🎀 — slay, iconic, exactly what you wanted.

or it returns ERR_PTR 💀 which is the "nope, something went wrong" pointer. so pls pls pls check it with IS_ERR() before you go dereferencing, i'm begging 🙈 that's not in the page, that's just me caring about you.

⚠️ fr fr: the return is either a valid pointer to the allocated PSP device or an ERR_PTR. it is not going to be NULL-and-chill, it's ERR_PTR. treat accordingly, bestie.
