💅 amdgpu_acpi_...shift_update(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual for amdgpu_acpi_...shift_update(9) — yes that name is a whole keyboard smash, but it's iconic and we're gonna get through it together 🫶

---

✨ NAME ✨

amdgpu_acpi_smart_shift_update — literally just updates the dGPU device state over to SBIOS 💫

---

🌸 SYNOPSIS 🌸

int amdgpu_acpi_smart_shift_update (struct amdgpu_device *adev , enum
       amdgpu_ss ss_state );

that's the whole vibe check right there — one function, two args, int out the front 🎀

---

🎯 ARGUMENTS 🎯

• adev — your amdgpu device pointer bestie, the main character of this call 💅
• ss_state — the current smart shift event, i.e. the moment we're living in right now ✨

---

🔥 DESCRIPTION 🔥

so what does it actually do?? it returns 0 on success 🎉 — and if things go sideways, it returns an error number instead. that's it, that's the whole story. no cap. 💀
