amdgpu_device_ip_early_init(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 amdgpu_device_ip_early_init — the kernel API manual, bestie edition 🎀

okay so you're reading the amdgpu_device_ip_early_init page from the Kernel API Manual, section 9. pull up a chair, we're doing this together 💖

✨ NAME ✨

amdgpu_device_ip_early_init — run early init for hardware IPs

like the name says, it's the early-init girlie for the hardware IPs. she goes first. she's the opening act 🎤

🌸 SYNOPSIS 🌸

int amdgpu_device_ip_early_init (struct amdgpu_device *adev );

that's the whole signature, no cap. one function, one argument, returns an int. iconic minimalism 💅

🦋 ARGUMENTS 🦋

  • adev — an amdgpu_device pointer. that's it, that's the argument. she's pointing at the device, she knows what to do with it ✨

💜 DESCRIPTION 💜

So this is the early initialization pass for the hardware IPs, and honestly? it's giving opening number energy 🔥

The hardware IPs that make up each asic are discovered, and then each IP's early_init callback is run. so: find all the IPs, then let each one do its little early-init thing 🧚

This is the first stage in initializing the asic — first stage only, don't get it twisted, there's more where this came from 👑

Return value vibes:

  • returns 0 on success 🎀
  • returns a negative error code on failure 😭
fr fr, if you get a negative number back, something went sideways. don't ignore it.
