pci_std_enable_acs(9)

💖 pci_std_enable_acs 💖

okay so bestie, welcome to the Kernel API Manual entry for pci_std_enable_acs ✨ this one is short and sweet and it's giving "small function, big responsibility" energy 🎀

---

🌸 NAME 🌸

pci_std_enable_acs — enable ACS on devices using standard ACS capabilities 💅

---

🦋 SYNOPSIS 🦋

void pci_std_enable_acs (struct pci_dev *dev , struct pci_acs *caps );

no cap, that's the whole signature 🫶

---

🌈 ARGUMENTS 🌈

• dev — the PCI device 🖥️ like, the actual device we're doing this to
• caps — default ACS controls ⚙️ the baseline knobs, if you will
