💅 radeon_acpi_...device_ready(9) 💅

okay so bestie, welcome to the Kernel API Manual 🎀 — yes this is a real kernel function name and yes the ... in the middle is genuinely how it's printed, we don't make the rules, we just slay within them ✨

🌸 NAME 🌸

radeon_acpi_pcie_notify_device_ready — literally the whole entry, that's it, that's the name, no trailing description because the manpage said so and we respect the source 🙈

---

✨ SYNOPSIS ✨

int radeon_acpi_pcie_notify_device_ready (struct radeon_device *rdev );

that's the whole vibe right there 🔥

---

🦋 ARGUMENTS 🦋

• rdev — a radeon_device pointer, bestie 💖 that's the one and only thing it takes

---

👑 DESCRIPTION 👑

so what does it do, you ask? 💅

It executes the PCIE_DEVICE_READY_NOTIFICATION method — and yeah, that applies to all asics (all of them, no exceptions, every single one 🫶).

It returns 0 on success, and an error on failure — so lowkey just check the return value and you're golden ngl ⭐

no cap: 0 = slay, error = not slay, that's the whole mood 💀
