okay so bestie, welcome to the kernel API manual for vcn_v4_0_5_hw_fini — yes that's a lot of underscores, no I will not be apologizing, and yes it's giving "my wifi password is a sentence" energy 💅. This is the ninth-section (kernel API) page for it, so like… driver-dev territory. Buckle up 🎀

🌸 NAME 🌸

vcn_v4_0_5_hw_fini — literally just stop the hardware block. That's the whole vibe. It shuts the thing down, periodt 🛑

✨ SYNOPSIS ✨

int vcn_v4_0_5_hw_fini (struct amdgpu_ip_block *ip_block );

yep, that's it, one argument, returns an int, we love a simple signature 🫶

🦋 ARGUMENTS 🦋

  • ip_block — a pointer to the amdgpu_ip_block for this hw instance. like, your specific block, not somebody else's, iykyk 👑

💖 DESCRIPTION 💖

So what does it actually do? It stops the VCN block 🛑 and marks the ring as not ready any more. That's the tea. No cap, that's the entire documented behaviour — stop the block, ring goes "nope, not ready," we move on ✨
