pci_configure_ari(9)

pci_configure_ari(9) 💅

okay bestie, welcome to the Kernel API Manual page for pci_configure_ari(9) — it's giving “tiny function, big ARI energy” ✨.

✨ NAME ✨

pci_configure_ari — enable or disable ARI forwarding 🎀

🌸 SYNOPSIS 🌸

void pci_configure_ari (struct pci_dev *dev );

🎀 ARGUMENTS 🎀

• dev — the PCI device 👑

🦋 DESCRIPTION 🦋

Okay so here's the whole vibe check: if dev and its upstream bridge both support ARI, this function enables ARI in the bridge. If that “both support ARI” condition is not met, it disables ARI in the bridge. That's the entire plot, no cap 😭.

💅 SEE ALSO 💅

Kernel file ./drivers/pci/pci.c is in the mix, and the SEE ALSO squad is literally enormous — like a group chat with every PCI bestie 💖:
