vcn_v1_0_mc_resume_spg_mode(9)

✨ NAME ✨

vcn_v1_0_mc_resume_spg_mode — it's the one that does the memory controller programming, bestie 💅

This lil page lives in the Kernel API Manual, and honestly? She's iconic in her own quiet way 🎀

---

🌸 SYNOPSIS 🌸

void vcn_v1_0_mc_resume_spg_mode (struct amdgpu_vcn_inst *vinst );

Like, that's the whole signature. No return value, no drama. void queen behavior 👑

---

🦋 ARGUMENTS 🦋

• vinst — the VCN instance 🫶 that's it, that's the whole argument. She just wants her instance and she's good to go.

---

💖 DESCRIPTION 💖

Okay so picture this: this function's whole job is literally just letting the VCN memory controller know its offsets. That's the flex. She walks in, tells the memory controller where its stuff lives, and dips ✨ no cap, that's the entire plot.
