✨ NAME ✨

pci_disable_pasid — turns OFF the PASID capability. yeah. that's it. that's the whole vibe. it disables it. 🔥

---

🌸 SYNOPSIS 🌸

void pci_disable_pasid (struct pci_dev *pdev );

literally just one function, one argument, returns nothing (void, she gives nothing back and that's iconic of her). ✨

---

🎀 ARGUMENTS 🎀

• pdev — the PCI device structure 💖 like, the actual device you're doing this to. that's the one you hand over.

no cap, that's the only argument. one (1) argument. she's lowkey minimalist.

• pci_enable_ats(9)
• pci_disable_ats(9)
• pci_ats_queue_depth(9)
• pci_ats_page_aligned(9)

• pci_enable_pasid(9)
• pci_restore_pasid_state(9)
• pci_pasid_features(9)
• pci_max_pasids(9)

like... she knows EVERYONE. the whole ats.c friend group fr fr 🧚 and yes pci_enable_pasid(9) is right there — that's her twin, the "turn it back on" one, iykyk 👑
