✨ vcn_v4_0_start_dpg_mode ✨

okay bestie, buckle up 💖 this one's from the Kernel API Manual and it's literally all about kicking off the VCN block in dpg mode. yes i said dpg mode. no i will not be explaining what the letters stand for, the manpage doesn't, and we do not invent lore here 🫶

🌸 NAME 🌸

vcn_v4_0_start_dpg_mode — VCN start with dpg mode. that's the whole vibe. short, sweet, iconic 👑

---

int vcn_v4_0_start_dpg_mode (struct amdgpu_vcn_inst *vinst , bool indirect );

she takes two things and returns an int, periodt 💅

---

🦋 ARGUMENTS 🦋

• vinst — the VCN instance. like, which one. the main character of this function call 🌟
• indirect — a bool, and it means "indirectly write sram". so like, write the sram, but make it indirect ✨

💜 DESCRIPTION 💜

Start VCN block with dpg mode. that's it. that's the description. no cap, the manpage is out here giving minimal effort and honestly? we respect the confidence 😭

so yeah — you call this and you're starting up the VCN block, and the mode is dpg mode. if you came here looking for a novel, bestie, the kernel docs said "no thoughts, head empty" 🙈
