📦 version 7.3.1, in nixpkgs unstable

💅 vcn_v1_0_early_init — the Kernel API Manual, but make it bestie ✨

okay so like, this is the manual page for vcn_v1_0_early_init(9), a kernel API function. yes bestie, we're doing kernel API today. main character energy fr fr. it lives in the AMD GPU driver and it's giving "let me set up your hardware before the real work starts" 💖

🎀 NAME 🎀

vcn_v1_0_early_init — set function pointers and load microcode

like literally, that's the whole vibe. it sets function pointers and loads microcode. both. at once. iconic.

✨ SYNOPSIS ✨

int vcn_v1_0_early_init (struct amdgpu_ip_block *ip_block );

so it takes one (1) argument and returns an int. cute, simple, no drama 🌸

🦋 ARGUMENTS 🦋

  • ip_block — Pointer to the amdgpu_ip_block for this hw instance. like, this is the specific hardware instance's little info block. don't lose it, it's important 🫶

💫 DESCRIPTION 💫

two jobs. that's it. two jobs and she ate:

  • Set ring and irq function pointers — yes, both the ring ones and the irq ones. no crumbs left.
  • Load microcode from filesystem — the microcode comes from a file on your filesystem, and this function goes and gets it. periodt.

👑 SEE ALSO 👑

the kernel file is ./drivers/gpu/drm/amd/amdgpu/vcn_v1_0.c and ngl there's a whole friend group of related functions, so let me introduce you:

and they all live over in ./drivers/gpu/drm/amd/amdgpu btw. iykyk 🌈

ok that's the whole page bestie. go set those function pointers. load that microcode. slay 💅✨
