amdgpu_devi..._gpu_info_fw(9)

📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_devi..._gpu_info_fw(9) — yes bestie, the header truncated it, the real one is amdgpu_device_parse_gpu_info_fw

okay so you're in the Kernel API Manual ✨ and this page is about one little function that does a genuinely huge job. yes the title up top gets chopped to amdgpu_devi..._gpu_info_fw(9) — that's just the header being dramatic, the actual name is in NAME below 👑

🌸 NAME 🌸

amdgpu_device_parse_gpu_info_fw — parse gpu info firmware. that's it, that's the vibe 🎀

🦋 SYNOPSIS 🦋

int amdgpu_device_parse_gpu_info_fw (struct amdgpu_device *adev );

like, one argument, one int back. lowkey elegant fr fr 💅

✨ ARGUMENTS ✨

  • adev — an amdgpu_device pointer. that's the whole thing. your GPU's whole identity, passed in as a pointer 🫶

🔥 DESCRIPTION 🔥

okay so here's what's actually happening: this function parses the asic configuration parameters that are specified in the gpu info firmware, and then it makes them available to the driver so the driver can use them when it's configuring the asic. the firmware says "here's what I am," this function reads it, and the driver gets to actually do something with that info. main character energy honestly 👑

and it returns 0 on success, and -EINVAL on failure. no cap, that's the return contract — memorize it, love it, respect it 💀

heads up bestie: failure means -EINVAL. that's the one you're checking for. don't go inventing other error codes, the page says -EINVAL periodt.

🌈 SEE ALSO 🌈

buckle up bestie, this list is long and every single one of these is invited to the party 🎉 first up, the actual kernel file this lives in:

  • Kernel file ./drivers/gpu/drm/amd/amdgpu/amdgpu_device.c

then the whole extended friend group, in exactly the order the manpage gives them:

like I said. a lot. slay that cross-reference game 💀✨

and that's the page, bestie 🫶 this one comes straight out of ./drivers/gpu/drm/amd/amdgpu and it's dated October 2026 — so yeah, future-coded manual page, iconic behavior honestly 💜🎀
