📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_atpx_verify_interface(9) — from the Kernel API Manual, bestie

okay so first things first, the full name is amdgpu_atpx_verify_interface — the header up top gets all truncate-y and shows it as amdgpu_atpx_...fy_interface(9), but that's just the manpage being dramatic and hiding letters. we know who she is. 💖

✨ NAME ✨

amdgpu_atpx_verify_interface — verify ATPX, that's it, that's the whole job 🫶

🌸 SYNOPSIS 🌸

int amdgpu_atpx_verify_interface (struct amdgpu_atpx *atpx );

🎀 ARGUMENTS 🎀

  • atpx — the amdgpu atpx struct, literally the thing we're poking at 💅

🦋 DESCRIPTION 🦋

so what this does is it runs the ATPX_FUNCTION_VERIFY_INTERFACE ATPX function, which initializes ATPX and figures out which features are actually supported — and yes, that applies to all asics, no exceptions, everyone gets the vibe check ✨

it returns 0 on success and an error on failure. no cap. that's the whole tea. 🍵

ngl, if it errors, something is off with the ATPX situation — the return value is your girl telling you it didn't work out. 😭

🌈 SEE ALSO 🌈

the kernel file lives right here, go look:

./drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c

and then the whole friend group of related functions, all of them, in order, because we don't leave anyone out 👑

like, read them, they're all iconic in their own way, iykyk 💜

and that's the page!! sign-off time: this little number comes from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and the manual name at the footer is that same truncated amdgpu_atpx_...fy_interface(9) — slay, go forth and verify that interface bestie 💅✨🎀
