🌸 radeon_atcs_verify_interface(9) 🌸

okay so bestie, welcome to the kernel API manual for radeon_atcs_verify_interface — yes that's the whole name, she's long but she's iconic 💅 this is a section 9 page, kernel API vibes only, and we're gonna get through it together, no cap.

✨ NAME ✨

radeon_atcs_verify_interface — verify ATCS 🦋

Like, literally the whole job is verification. She checks the vibes. She confirms the interface. Main character energy fr.

---

✨ SYNOPSIS ✨

int radeon_atcs_verify_interface (acpi_handle handle , struct
radeon_atcs *atcs );

so she's an int function, she takes two things, that's it, that's the whole signature 🎀

---

✨ ARGUMENTS ✨

• handle — the acpi handle 💖 lowkey just an ACPI handle, you know how it is
• atcs — the radeon atcs struct 🌸 your struct radeon_atcs *, handed over and ready to be worked on

---

✨ DESCRIPTION ✨

okay so here's the tea ☕ she executes the ATCS_FUNCTION_VERIFY_INTERFACE ATCS function — yes, that exact function — to initialize ATCS and figure out which features are supported. and like, on all asics, no exceptions bestie 🫶

then she returns 0 on success, and an error on failure. that's it. that's the whole deal. simple, clean, ate 💀✨

ngl bestie, that's a whole friend group of ACPI functions and they all live together in ./drivers/gpu/drm/radeon — go say hi 👑

mwah 💋 that's the page! this little gift came from the ./drivers/gpu/drm/radeon source, dated October 2026, and she's filed under radeon_atcs_...fy_interface(9) in the Kernel API Manual — go forth and verify those interfaces, bestie, you're gonna slay 🎀💖✨
