okay so bestie, you're on the vcn_v4_0_en...power_gating(9) page from the Kernel API Manual, and the function at the center of the group chat is vcn_v4_0_enable_static_power_gating. It’s giving “enable VCN static power gating,” and we’re gonna keep every detail intact. 💅✨

💖 NAME 💖

vcn_v4_0_enable_static_power_gating — enable VCN static power gating. That’s the whole name, and yes, it ate. 👑

🌸 SYNOPSIS 🌸

       void vcn_v4_0_enable_static_power_gating (struct amdgpu_vcn_inst *vinst
       );

🦋 ARGUMENTS 🦋

• vinst — VCN instance. That’s the one and only argument, bestie: a VCN instance. No extra lore. 💜

✨ DESCRIPTION ✨

Enable static power gating for VCN block. That’s the vibe: turn on static power gating for the VCN block, periodt. It’s not deep, it’s just very cunty about doing exactly that. 💅
