💖 tb_domain_di...domain_paths(9) 💖

okay so this is from the Kernel API Manual, and bestie, we're looking at tb_domain_disconnect_xdomain_paths — it's highkey giving "turn off the DMA paths for XDomain" energy. No cap, every deet is here. 🦋

✨ NAME ✨

tb_domain_disconnect_xdomain_paths — Disable DMA paths for XDomain 💅

🌸 SYNOPSIS 🌸

int tb_domain_disconnect_xdomain_paths (struct tb *tb , struct
       tb_xdomain *xd , int transmit_path , int transmit_ring , int
       receive_path , int receive_ring );

🎀 ARGUMENTS 🎀

Here's the cast, okay? no skipping:

• tb — the domain disabling the DMA paths.
• xd — the XDomain whose DMA paths are disconnected.
• transmit_path — the HopID we are using to send out packets.
• transmit_ring — the DMA ring used to send out packets.
• receive_path — the HopID the other end is using to send packets to us.
• receive_ring — the DMA ring used to receive packets from receive_path.

💅 DESCRIPTION 💅

the way that it calls the connection manager specific method to disconnect DMA paths to the XDomain in question. That's the whole plot. Periodt. ✨

🫶 RETURN 🫶

• 0 — on success, slay.
• -ENOTSUPP — if the connection manager implementation does not support XDomains. 😭
• Negative errno — an error occurred. 💀
