💅 vcn_v4_0_5_set_clockgating_state(9) — aka the Kernel API Manual glow-up ✨

okay so bestie, welcome to the Kernel API Manual section 9, and today's main character is vcn_v4_0_5_set_clockgating_state(9). yes the name is a whole mouthful, no we're not shortening it, it's iconic and we respect it 🎀

✨ NAME ✨

vcn_v4_0_5_set_clockgating_state — sets the clockgating state of the VCN block. that's it, that's the whole vibe 🦋

🌸 SYNOPSIS 🌸

int vcn_v4_0_5_set_clockgating_state (struct amdgpu_ip_block *ip_block ,
enum amd_clockgating_state state );

literally just one function returning an int, taking two args, slaying quietly in the kernel 🫶

💜 ARGUMENTS 💜

  • ip_block — an amdgpu_ip_block pointer, i.e. the little handle that says "hi yes this is the IP block we're talking about" 💅
  • state — the clock gating state. that's the value telling the function what clockgating situation we're in ✨

🌈 DESCRIPTION 🌈

set the VCN block clockgating state. no cap, that's the description. it sets it. it's giving "short and confident" and honestly? obsessed 😌

lowkey the whole manpage is short — but every detail is here, fr fr, so don't come for me 💀
