💅 pci_ari_enabled(9) — a Kernel API Manual moment

Okay bestie, welcome to the pci_ari_enabled(9) page, straight out of the Kernel API Manual. It's a lil' one, but it's iconic in its own way 🎀

✨ NAME ✨

pci_ari_enabled — query ARI forwarding status 👑

Yeah. That's the whole gig. We're checking on ARI forwarding. Main character behavior fr fr.

---

🌸 SYNOPSIS 🌸

bool pci_ari_enabled (struct pci_bus *bus );

It takes a struct pci_bus *bus and hands you back a bool. Simple. Elegant. Ate. 💖

---

🦋 ARGUMENTS 🦋

• bus — the PCI bus 🌈 (that's it, that's the whole argument, she's lowkey undemanding)

---

💫 DESCRIPTION 💫

So here's the tea ☕ — this function returns true if ARI forwarding is enabled. That's literally the entire description, no cap. If it's on, you get true; if it's not, you don't. Vibe check complete ✅

Ngl bestie, that's all the manpage gives us, so we're not gonna invent extra lore. The facts are the facts, periodt. 💅
