💅 pci_enable_pasid — it's giving "turn on the PASID" energy ✨

okay so this is pci_enable_pasid(9) from the Kernel API Manual, and honestly bestie, it's a little one but she's important 🎀

🌸 NAME 🌸

pci_enable_pasid — Enable the PASID capability. that's it, that's the vibe. she does exactly what it says on the tin, no cap 💖

✨ SYNOPSIS ✨

int pci_enable_pasid (struct pci_dev *pdev , int features );

literally just hand her the device and the features and she'll do her thing 🫶

🦋 ARGUMENTS 🦋

  • pdev — the PCI device structure. like, the device you're trying to enable PASID on. main character energy, she needs to know who she's working with 💜
  • features — the features to enable. yep. that's the list of what you want turned on 🔥

🌈 DESCRIPTION 🌈

okay so here's the tea: this function returns 0 on success, and a negative value on error. periodt ✨

and here's the part where she's lowkey a responsible queen 👑 — she actually checks whether the features are really supported by the device, and if they're not, she returns an error. no silently pretending it worked, no fake vibes, she does her homework first 📚💅

ngl that's the whole thing. short and iconic. not every function needs a whole essay 💀
