amdgpu_acpi_init(9)

okay so bestie, this page is straight out of the Kernel API Manual, and it's giving “tiny but important init function” energy. let's get into it 💅✨

---

💖 NAME 💖

amdgpu_acpi_init — init driver acpi support. that's the whole vibe, no cap 🫶

🌸 SYNOPSIS 🌸

here's the signature, and yes, copy it exactly please:

int amdgpu_acpi_init (struct amdgpu_device *adev );

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. literally the device pointer you're handing over, bestie 🦋

✨ DESCRIPTION ✨

so this function verifies the AMD ACPI interfaces and registers with the acpi notifier chain — and yes, that's for all asics, periodt 💅🔥

it returns 0 on success, and an error on failure. iconic behavior, honestly 😭👑

no cap: success is 0, failure is an error. that's the whole return situation 🫶
