amdgpu_atif_...probe_handle(9)

💅 amdgpu_atif_pci_probe_handle — like, the whole vibe

okay so you're in the Kernel API Manual bestie, and this page is literally amdgpu_atif_...probe_handle(9) — say that five times fast, i can't 😭 anyway it's the ATIF handle looker-upper and it's giving "small function, big responsibility." let's get into it ✨

---

✨ NAME ✨

amdgpu_atif_pci_probe_handle — the girl whose whole job is looking up the ATIF handle 🔍💖

---

🦋 SYNOPSIS 🦋

bool amdgpu_atif_pci_probe_handle (struct pci_dev *pdev );

like, that's it. one argument, one bool. no cap, she's lowkey minimal 📦

---

🎀 ARGUMENTS 🎀

• pdev — the pci device. that's the whole description bestie, it's a pci device, she's a pci device, we move 💅

---

🌸 DESCRIPTION 🌸

so what does she actually do? she looks up the ATIF handles — for all asics, periodt, no exceptions 💯

and then she tells you how it went:

• returns true if the handle is found 👑
• returns false if not 🙈

that's the entire plot and honestly? iconic. main character energy from a function that returns a bool 🫶

mwah 💋 that's the page. she's short, she's sweet, she returns a bool.

this lil gem came from ./drivers/gpu/drm/amd/amdgpu and she's stamped October 2026 — bestie is from the future and she's still just looking up handles 💀✨ slay.
