amdgpu_acpi_...device_ready(9)

💅 amdgpu_acpi_pcie_notify_device_ready(9) — the Kernel API Manual, bestie edition 🎀

okay so this is a page straight out of the Kernel API Manual, and it's all about amdgpu_acpi_pcie_notify_device_ready. yes that's a long name. no we're not shortening it. it's giving "my mom named me after the whole family tree" energy and we respect it. 🦋

✨ NAME ✨

amdgpu_acpi_pcie_notify_device_ready — that's it, that's the name. the description slot is literally empty, and honestly? sometimes you just show up, say your name, and leave. main character energy fr fr. 👑

---

🌸 SYNOPSIS 🌸

int amdgpu_acpi_pcie_notify_device_ready (struct amdgpu_device *adev );

copy it. paste it. don't touch the spacing. 💅

---

🫶 ARGUMENTS 🫶

• adev — an amdgpu_device pointer. that's the whole mood. it's the GPU's little passport, and we're handing it over.

---

🔥 DESCRIPTION 🔥

so what does it actually do? it executes the PCIE_DEVICE_READY_NOTIFICATION method — on all asics, no exceptions, no faves. ⭐

and it's a real one about the return value, ngl:

• returns 0 on success 🎉
• returns an error on failure 😭

that's it. that's the function. it walks in, it screams "the device is READY" into the ACPI void, and it comes back with a status code. iconic behavior. ate and left no crumbs. 💀

ngl the whole atif / atcs / acpi cluster is a lot to hold in your head at once, but that's literally why manpages exist. you got this. 🍓
