do_unregister_con_driver(9)

💖 do_unregister_con_driver(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's all about politely ✨leaving✨ the console layer. it's do_unregister_con_driver, and yeah it's giving "cleanup era" 🧹

---

✨ NAME ✨

do_unregister_con_driver — unregister console driver from console layer 🎀

✨ SYNOPSIS ✨

int do_unregister_con_driver (const struct consw *csw );

✨ ARGUMENTS ✨

• csw — the console driver 👑 (that's it, that's the whole argument, she's lowkey simple like that)

✨ DESCRIPTION ✨

okay so listen up, this is important fr fr 🫶

All drivers that registers to the console layer must call this function upon exit — like, must, no cap. it's not optional, it's not a vibe, it's a requirement 💅

and it's also the move if the console driver ends up in a state where it won't be able to handle console services 😭 — the manpage gives a very specific example: such as the framebuffer console without loaded framebuffer drivers. so if your framebuffer console ain't got her framebuffer drivers loaded, she can't serve, and it's time to unregister. periodt.

⚠️ ok and here's the rule that matters: The driver must unbind first prior to unregistration. unbind first, then unregister. do not skip this. do not do it backwards. the order is the whole point 🚨
