pci_prg_resp_pasid_required(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

pci_prg_resp_pasid_required — the little function that tells you the PRG Response PASID Required bit status, no cap 🎀

okay so this is from the Kernel API Manual, bestie, and it's honestly such a short little icon. Let's get into it 🫶

✨ SYNOPSIS ✨

int pci_prg_resp_pasid_required (struct pci_dev *pdev );

that's it. that's the whole vibe. one function, one argument, one int coming back at you 💅

🦋 ARGUMENTS 🦋

  • pdev — the PCI device structure 💻 like, the actual device you're asking about. she's the main character here.

🌸 DESCRIPTION 🌸

So what does she do? Bestie. She literally just tells you:

  • returns 1 if PASID is required in the PRG Response Message ✅
  • returns 0 otherwise 🙈

that's the entire personality. one bit of truth. no cap, it's giving "short and iconic" 💀✨

ngl, if you were hoping for a long lore drop, this is not that page. she says what she means and dips. periodt.

🔥 SEE ALSO 🔥

the whole friend group lives in the kernel file ./drivers/pci/ats.c — go say hi to the rest of the squad:

like, imagine the group chat. this function is in there, lowkey just answering one question and letting everyone else do the heavy lifting 🧚💜

and that's the tea! ☕ sign-off time: this page lives under the source path ./drivers/pci, dated October 2026, straight from the Kernel API Manual. mwah, go read the rest of the ATS/PRI/PASID girlies, they ate 💅👑
