radeon_acpi_init(9)

💖 NAME 💖

radeon_acpi_init — init driver acpi support 🎀✨

okay so this is the radeon_acpi_init(9) page, straight outta the Kernel API Manual, and it's giving very specific kernel-driver energy. periodt.

---

🌸 SYNOPSIS 🌸

int radeon_acpi_init (struct radeon_device *rdev );

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer, bestie. that's the whole argument, no cap 🫶

---

🦋 DESCRIPTION 🦋

so here's the vibe check: this function verifies the AMD ACPI interfaces and registers with the acpi notifier chain (all asics). lowkey iconic of it.

it returns 0 on success, and an error on failure. that's it, that's the whole plot 💅

no cap: success is 0, failure is an error — don't get it twisted 😭
