💅 amdgpu_irq_add_domain(9) — the Kernel API Manual of it all

okay so this is amdgpu_irq_add_domain(9) from the Kernel API Manual, and bestie, it's shorter than your attention span during a lecture but it still slays. it's a kernel function, it does one thing, and it does it well. periodt. 💖

✨ NAME ✨

amdgpu_irq_add_domain — literally creates a linear IRQ domain. that's the whole job. iconic honestly.

🦋 SYNOPSIS 🦋

int amdgpu_irq_add_domain (struct amdgpu_device *adev );

ok so you pass in the device pointer and it hands you back an int. we love a simple signature. no cap.

🎀 ARGUMENTS 🎀

  • adev — this is your amdgpu device pointer, the main character of the whole amdgpu situation. you give it the device, it gives you (hopefully) zero. 🤝

🌸 DESCRIPTION 🌸

so what it does is it creates an IRQ domain for GPU interrupt sources that might be driven by another driver. yes, another one. like ACP for example — it's giving "i can't do this alone and that's okay". 🫶

the way this thing exists is to be the shared hallway where the amdgpu interrupts and some other driver's interrupts can both live. mutual cooperation. networking. a little collab. 💅

🌈 RETURN 🌈

  • 0 on success ✨ (the best number, the only number we stan)
  • an error code otherwise 😭 (boo, but at least it tells you)

🔥 SEE ALSO 🔥

okay this list is long because the amdgpu IRQ code is a whole friend group, and honestly we respect that.

the kernel file lives at ./drivers/gpu/drm/amd/amdgpu/amdgpu_irq.c — that's the home base, the group chat where all of these hang out:

yeah. that's the whole crew. go read them, iykyk. 📚

quick vibe check: this domain is for GPU interrupt sources that may be driven by another driver — so if you're wondering why amdgpu is sharing its toys, that's why. sharing is caring, bestie. 🧚

and that's the page, fr fr. brought to you by the source at ./drivers/gpu/drm/amd/amdgpu, dated October 2026, version amdgpu_irq_add_domain(9) 🍓 — stay hydrated, read your kernel docs, and remember: zero on success is the only number we accept. 👑💜
