vcn_v3_0_mc_resume(9)

💖 NAME 💖

Okay bestie, welcome to the vcn_v3_0_mc_resume(9) page from the Kernel API Manual — manual name folded in right here because we're cute like that. The function is vcn_v3_0_mc_resume, and its whole thing is memory controller programming, VCN edition. Lowkey iconic. Not me being obsessed with a kernel function, but here we are 💅.

🌸 SYNOPSIS 🌸

void vcn_v3_0_mc_resume (struct amdgpu_vcn_inst *vinst );

That's the signature, fr fr. It returns void, so nothing comes back — the function just does its little memory-controller moment and dips. ✨

🎀 ARGUMENTS 🎀

• vinst — VCN instance. That's the one and only argument, no cap. One VCN instance, periodt.

💅 DESCRIPTION 💅

The description is literally: "Let the VCN memory controller know it's offsets". Yep, it's offsets, apostrophe included — we're keeping it exactly as the page says. So the vibe is: VCN memory controller gets clued in on it's offsets. That's the whole description, no extra lore, no secret bonus paragraphs. Highkey straightforward. 🎀
