ntb_transport_max_size(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to ntb_transport_max_size(9) from the Kernel API Manual 🎀 this one is short and sweet: it’s the little query that tells you the biggest payload a queue can handle. no cap.

💖 NAME 💖

ntb_transport_max_size — query the max payload size of a qp 💅

✨ SYNOPSIS ✨

unsigned int ntb_transport_max_size (struct ntb_transport_qp *qp );

that’s the whole signature, character for character — it returns an unsigned int and takes a struct ntb_transport_qp * named qp ✨

🌸 ARGUMENTS 🌸

  • qp — the NTB transport layer queue to be queried, bestie. like, this is the queue you’re asking about 🫶

🦋 DESCRIPTION 🦋

Query the maximum payload size permissible on the given qp 🌈

so you hand over the qp, and this function is basically doing the vibe check: what’s the maximum payload size allowed on this queue? that’s the whole mood. it’s giving “ask and receive,” not “guess and stress” 💅

⭐ RETURN ⭐

the max payload size of a qp 👑

that’s the answer it hands back. periodt.
