amdgpu_devic...gating_state(9)

✨ NAME ✨

okay so bestie, this is a page from the Kernel API Manual (yes, that's the manual name, we're being fancy today 💅) and it's all about amdgpu_device_ip_set_clockgating_state — which is literally the function that sets the CG state 🔥

🌸 SYNOPSIS 🌸

int amdgpu_device_ip_set_clockgating_state (struct amdgpu_device *adev ,
enum amd_ip_block_type block_type , enum amd_clockgating_state state );

like, that's the whole signature, no cap — copy it exactly, she's iconic 🎀

---

🦋 ARGUMENTS 🦋

• adev — it's an amdgpu_device pointer. that's it, that's the whole vibe 🫶
• block_type — the type of hardware IP you're dealing with (SMU, GFX, UVD, etc.) — the "etc." is doing so much work here ngl
• state — the clockgating state, and your two moods are gate or ungate 🙈💀

---

⭐ DESCRIPTION ⭐

So what does she actually do? She sets the requested clockgating state for all instances of the hardware IP you specified. every single one. she's thorough like that 💅✨

And the return value? It's the error code from the last instance. not the first, not the best one — the last one. main character energy honestly 👑
