vcn_v2_5_hw_init(9)

💖 NAME 💖

vcn_v2_5_hw_init — bestie, this is the one that starts and tests the VCN block ✨

So this page is from the Kernel API Manual, section 9, and the star of the show is vcn_v2_5_hw_init. Obsessed already.

---

🌸 SYNOPSIS 🌸

int vcn_v2_5_hw_init (struct amdgpu_ip_block *ip_block );

That's the whole vibe: you hand it an ip_block and it gives you back an int. Simple. Iconic. 🎀

---

🦋 ARGUMENTS 🦋

• ip_block — a pointer to the amdgpu_ip_block for this hw instance. Like, this specific one, not a random one, okay? iykyk 💅

---

✨ DESCRIPTION ✨

Okay 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 it. That's the whole job. Hardware up, VCPU awake, and then a vibe check to make sure nothing's being weird. Slay. 💜
