💖 uvd_v7_0_hw_init — a kernel API manual moment ✨

okay so bestie, welcome to the uvd_v7_0_hw_init(9) page, straight out of the Kernel API Manual. this is the glow-up guide for the UVD block and ngl it's a short one but it ate. let's get into it 🎀

---

✨ NAME ✨

uvd_v7_0_hw_init — start and test the UVD block, no cap 🫶

---

🌸 SYNOPSIS 🌸

int uvd_v7_0_hw_init (struct amdgpu_ip_block *ip_block );

that's it, that's the signature. returns an int because obviously we gotta know if it slayed or flopped 💅

---

🦋 ARGUMENTS 🦋

• ip_block — Pointer to the amdgpu_ip_block for this hw instance. literally just the handle for the hardware instance we're working with, mwah 💜

---

🧚 DESCRIPTION 🧚

so what does it actually do? three things, and they're all main character energy:

1. Initialize the hardware 🔥
2. Boot up the VCPU 👑
3. Do some testing ⭐

that's the whole vibe check. it starts the block up and pokes at it to make sure it's alive. periodt.
