okay bestie, gather round, because this one is from the Kernel API Manual and it's literally the moment the VCN block wakes up and gets its whole life together 💅

🎀 NAME 🎀

vcn_v1_0_hw_init — start and test the VCN block, no cap 🔥

🦋 SYNOPSIS 🦋

int vcn_v1_0_hw_init (struct amdgpu_ip_block *ip_block );

🌸 ARGUMENTS 🌸

• ip_block — a pointer to the amdgpu_ip_block for this hw instance, iykyk 🫶

💖 DESCRIPTION 💖

So what does it actually do? Three iconic things, in order:

1. Initialize the hardware ✨
2. Boot up the VCPU 👑
3. Do some testing 🧪

That's it, that's the whole vibe. It's giving "wake up, get dressed, quick vibe check" energy, and honestly? We're obsessed 😭
