💅 host1x_device_exit(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, it's giving study date energy 🎀

---

✨ NAME ✨

host1x_device_exit — the lil function that uninitializes a host1x logical device 🧚

---

🌸 SYNOPSIS 🌸

int host1x_device_exit (struct host1x_device *device );

---

🦋 ARGUMENTS 🦋

• device — the host1x logical device, aka the main character of this whole page 👑

---

💖 DESCRIPTION 💖

so here's the vibe: when the driver for a host1x logical device gets unloaded, it can call this function to tear down each of its clients. like, all of them. every single one. no stragglers 🫶

typically you do this after a subsystem-specific data structure has already been removed and the functionality can no longer be used — so at that point there's literally nothing left to do except clean up, and that's exactly what this little icon does 💅
