🎀 NAME 🎀

vcn_v2_0_early_init — sets up the function pointers and loads the microcode 🫶

---

🌸 SYNOPSIS 🌸

int vcn_v2_0_early_init (struct amdgpu_ip_block *ip_block );

like, that's the whole signature, no cap ✨

---

🦋 ARGUMENTS 🦋

• ip_block — a pointer to the amdgpu_ip_block for this hw instance. like specifically this one, not a vibe-adjacent one 💅

---

💜 DESCRIPTION 💜

okay so here's the tea 🍓 two things happen in here:

1. it sets the ring and irq function pointers
2. it loads the microcode from the filesystem

that's it, that's the whole job. lowkey efficient, highkey essential 🔥
