vcn_set_powergating_state(9)

💖 vcn_set_powergating_state 💖

okay bestie, so this little gem lives in the Kernel API Manual — it's vcn_set_powergating_state(9), and honestly? the name is doing a lot of the work for us here. it's a function that sets the VCN block's powergating state. that's the whole vibe. but let's actually break it down so you can flex on people at parties 🎀

✨ NAME ✨

vcn_set_powergating_state — set VCN block powergating state

like… yes, the name is literally the description. iconic of it. 👑

---

🌸 SYNOPSIS 🌸

int vcn_set_powergating_state (struct amdgpu_ip_block *ip_block , enum
amd_powergating_state state );

so it returns an int (the classic "did it work or not" integer moment), takes a struct amdgpu_ip_block * named ip_block, and an enum amd_powergating_state named state. copy it exactly if you're writing it out, bestie, no creative liberties 💅

---

🦋 ARGUMENTS 🦋

• ip_block — an amdgpu_ip_block pointer. that's the block you're pointing at. it's a pointer. to an amdgpu_ip_block. we love a self-explanatory parameter 🫶
• state — the power gating state. the state. of the power gating. that's it, that's the whole parameter 😭

---

⭐ DESCRIPTION ⭐

Set VCN block powergating state.

that's genuinely the entire description, and honestly? respect. no filler, no 40-line lore dump, just the facts delivered with main character energy. you hand it the block, you hand it the state, it sets the powergating state of the VCN block. periodt. 🔥

🌈 SEE ALSO 🌈

• the kernel file ./drivers/gpu/drm/amd/amdgpu/amdgpu_vcn.c — go read the source if you want the real tea 🍓
• amdgpu_vcn_ring_reset(9) — its little friend, definitely worth a vibe check ✨

---

ok so lowkey the whole page is like four lines long and I'm obsessed with it. no warnings, no deprecated behaviour, no footguns listed — just a clean little setter. ngl, that's the dream 💀💖

and that's the tea, bestie 🧚 this one ships out of ./drivers/gpu/drm/amd/amdgpu, dated October 2026, straight from the Kernel API Manual — vcn_set_powergating_state(9), slaying in a terminal near you 👑💜
