💅 vcn_v4_0_di...clock_gating(9) — Kernel API Manual ✨

okay so real talk, bestie, we're deep in the amdgpu source tree today and this tiny function is the whole entire moment. it lives in the Kernel API Manual, and yes, the header truncates the name with ... because even the docs ran out of room. iconic behavior honestly 🎀

🌸 NAME 🌸

vcn_v4_0_disable_clock_gating — literally just turns VCN clock gating off. that's it. that's the whole vibe. 💅

✨ SYNOPSIS ✨

void vcn_v4_0_disable_clock_gating (struct amdgpu_vcn_inst *vinst );

returns nothing (void, as in "no return value, don't @ me"), takes exactly one pointer, and gets straight to business. no cap. 🦋

🫶 ARGUMENTS 🫶

  • vinst — the VCN instance. that's the one and only thing you hand over. it's a struct amdgpu_vcn_inst *, and it's giving "main character pointer energy" because without it this function has nothing to work on 👑

💖 DESCRIPTION 💖

Disable clock gating for the VCN block. periodt. 🔥

like, the function's entire personality is: clock gating was happening, and now it is not. that's the tea. if you were expecting a novel, this is not that function — it's the "one job, done well" girlie of the vcn_v4_0.c file 🧚

ngl, this page is short, but the info is precious — every word here is load-bearing. don't skip the one-liner, bestie, it's literally the whole manpage 🌈
