💅 radeon_atif_verify_interface(9) — Kernel API Manual, bestie ✨

okay so this is a page from the Kernel API Manual, and the star of the show is radeon_atif_verify_interface(9). like yes the header got chopped up into radeon_atif_...fy_interface(9) because man page headers are dramatic like that, but we know who she is 💖

✨ NAME ✨

radeon_atif_verify_interface — verify ATIF 🫶

---

🌸 SYNOPSIS 🌸

int radeon_atif_verify_interface (acpi_handle handle , struct
radeon_atif *atif );

that's the whole signature, no cap, copy it exactly 😌

---

🎀 ARGUMENTS 🎀

• handle — the acpi handle 💫 like, that's the thing you hand over
• atif — the radeon_atif struct 🌈 your little bundle of ATIF data

---

🦋 DESCRIPTION 🦋

okay so what she does: she executes the ATIF_FUNCTION_VERIFY_INTERFACE ATIF function to initialize ATIF and figure out what features are supported — and this happens on all asics, periodt 💅 every single one, no exceptions.

and the tea on return values ☕ she returns 0 on success, and an error on failure. that's it, that's the vibe check 😭
