amdgpu_acpi_get_node_id(9)

💅 amdgpu_acpi_get_node_id — a kernel API manual moment

okay so bestie, welcome to the amdgpu_acpi_get_node_id(9) page from the Kernel API Manual ✨ — it's short, it's sweet, and it's literally here to tell you which NUMA node your GPU lives in 🎀

---

🌸 NAME

amdgpu_acpi_get_node_id — obtain the NUMA node id for corresponding amdgpu acpi device handle

like, that's the whole gig. you hand it a handle, it hands you a node id. iykyk 🦋

---

✨ SYNOPSIS

acpi_status amdgpu_acpi_get_node_id (acpi_handle handle , struct
       amdgpu_numa_info **numa_info );

look at her. two arguments. zero drama. 💅

---

🫶 ARGUMENTS

• handle — the acpi handle 💖 that's your entry point, your little key to the ACPI world
• numa_info — an amdgpu_numa_info structure holding numa information 🌈 (yes, it's a double pointer, she's fancy like that)

---

👑 DESCRIPTION

So basically it queries the ACPI interface to fetch the corresponding NUMA Node ID for a given amdgpu acpi device 🔍✨ highkey useful.

Returns ACPI STATUS OK with the Node ID on success, or the corresponding failure reason 😭 — so if it doesn't slay, it at least tells you why it didn't slay. fr fr no guessing required.
