💅 vcn_v4_0_5_hw_init — kernel API manual, but make it make sense

okay so bestie, welcome to the vcn_v4_0_5_hw_init(9) page ✨ this is a Linux kernel API manual entry, and it's literally all about the VCN block. no cap.

✨ NAME ✨

vcn_v4_0_5_hw_init — start and test the VCN block 🎀

like, that's the whole vibe. it starts it, and it tests it. main character energy fr fr.

🌸 SYNOPSIS 🌸

int vcn_v4_0_5_hw_init (struct amdgpu_ip_block *ip_block );

yep, that's it. one function, takes one pointer, gives you back an int. iconic.

🦋 ARGUMENTS 🦋

  • ip_block — a pointer to the amdgpu_ip_block for this hw instance. that's it, that's the whole argument list. she's low maintenance 💅

💜 DESCRIPTION 💜

so what does she actually do? three things, and they're honestly kinda big:

  1. initialize the hardware
  2. boot up the VCPU
  3. do some testing

that's literally the entire description. no elaboration, no extra tea. she initializes, she boots the VCPU, she tests. periodt. 👑

ngl the manpage doesn't say what the testing covers or what happens if it fails, so i'm not gonna make anything up. we don't do fanfic here 🫶

🔥 SEE ALSO 🔥
