💅 faux_device_create(9) — from the Kernel API Manual, bestie

okay so this is faux_device_create(9), and before you even ask — yes, the whole page lives under ./drivers/base, and yes it's dated October 2026. we'll get to the cute sign-off at the end, don't rush me 🎀

✨ NAME ✨

faux_device_create — the function that creates a faux device and registers it with the driver core, in one glorious little move 🦋

---

🌸 SYNOPSIS 🌸

struct faux_device * faux_device_create (const char *name , struct
device *parent , const struct faux_device_ops *faux_ops );

literally just three things and you get a device back, iykyk 💅

---

🎀 ARGUMENTS 🎀

• name — the name of the device we're adding. heads up: it must be unique for all faux devices. no duplicates, no "wait I thought that was mine", periodt 💀
• parent — a pointer to a potential parent struct device. if you set it to NULL, the device gets created in the "root" of the faux device tree in sysfs. main character device energy, no parent, living in the root directory 🌈
• faux_ops — the struct faux_device_ops that the new device will call back into. it can be NULL if you're not about that callback life 🙈

---

🔥 DESCRIPTION 🔥

so basically: create a new faux device, then register it in the driver core properly. slay, we love a correct registration 🫶

if present, the callbacks in faux_ops will be called with the device, so the caller can do something with it at the proper time given the device's lifecycle. it's giving ✨managed✨

⚠️ okay bestie, listen — when this function is called, the functions specified in struct faux_ops can be called before the function returns. so be prepared for everything to be properly initialized before that point in time. no cap, don't assume you get to finish your setup first 😭

---

👑 RETURN 👑

• NULL if an error happened with creating the device 💀
• a pointer to a valid struct faux_device that's registered with sysfs ✨
