🌸 amdgpu_atombios_fini(9) 🌸

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a short one but it's kind of iconic. it's giving "last one to leave the party turns off the lights" energy 💡✨

✨ NAME ✨

amdgpu_atombios_fini — free the driver info and callbacks for atombios 🫶

like, it's the cleanup crew. the friend who helps you pack up after the function. we love her for it.

---

🎀 SYNOPSIS 🎀

void amdgpu_atombios_fini (struct amdgpu_device *adev );

no return value, bestie. she just does the thing and dips 💅

---

🦋 ARGUMENTS 🦋

• adev — amdgpu_device pointer 📍 that's it. that's the whole argument list. one (1) pointer, and she's the main character.

---

💖 DESCRIPTION 💖

so what does she actually do? she frees the driver info and register access callbacks for the ATOM interpreter (r4xx+). 🧹✨

basically all that ATOM interpreter setup — the driver info, the register access callbacks — gets released here. and when does this get called? at driver shutdown. 🚪🌙 literally the "ok we're done here, everybody out" moment for the driver.

lowkey important: this is the teardown counterpart. if amdgpu_atombios_init(9) is the glow-up, this is the... un-glow-up? the cleanup. the self-care of releasing your resources 💆‍♀️

💜 sign-off 💜

that's the whole page, bestie — short, sweet, and doing exactly one job 😭🫶 this came from the source over at ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and yes it's still filed under amdgpu_atombios_fini(9) because some things never change 💅 periodt.
