vcn_v4_0_set...gating_state(9)

✨ vcn_v4_0_set_clockgating_state ✨

okay bestie, we're diving into the kernel today and honestly? this function is lowkey iconic. it's living in the manual named vcn_v4_0_set...gating_state(9) (the name's a little mysterious but we love that for her).

---

🌸 NAME 🌸

vcn_v4_0_set_clockgating_state — literally just sets the clockgating state for the VCN block. that's it. that's the whole vibe. 🎀

---

💅 SYNOPSIS 💅

int vcn_v4_0_set_clockgating_state (struct amdgpu_ip_block *ip_block ,
enum amd_clockgating_state state );

---

🦋 ARGUMENTS 🦋

• ip_block — an amdgpu_ip_block pointer. yeah she's a pointer. she points. iconic behavior honestly 💖
• state — the clock gating state (an enum amd_clockgating_state). this is the mood you're setting, the vibe you're choosing ✨

---

🌈 DESCRIPTION 🌈

so like. what does she do? she sets the VCN block clockgating state. periodt. no cap, no extra lore, just pure function. main character energy but make it clocks. 💀

okay and before i go — huge shoutout to ./drivers/gpu/drm/amd/amdgpu, dated October 2026, for hosting this whole slay. and to the vcn_v4_0_set...gating_state(9) manual (Kernel API Manual, same energy). we stan. 🫶✨💅
