💅 ntb_peer_mw_clear_trans — bestie's guide to clearing that outbound window ✨

okay so real talk, this is a page straight out of the Kernel API Manual, section 9, and it's about ntb_peer_mw_clear_trans. yes the name is a whole mouthful, no we're not changing it, that's her name and it's iconic 🎀

🌸 NAME 🌸

ntb_peer_mw_clear_trans — clear the translation address of an outbound memory window 💫

like literally, you're undoing the translation on an outbound memory window. that's the whole vibe check.

✨ SYNOPSIS ✨

int ntb_peer_mw_clear_trans (struct ntb_dev *ntb , int pidx , int widx );

she takes three args and returns an int. short and sweet, we love a low-maintenance signature 🫶

🦋 ARGUMENTS 🦋

  • ntb — the NTB device context. like, which device are we even talking to bestie 💀
  • pidx — the port index of the peer device. gotta know which peer, iykyk 🌈
  • widx — the memory window index. which window we clearing, bestie? window widx, obviously 👑

💖 DESCRIPTION 💖

so what she does is clear the translation of an outbound memory window. after that, the local device may no longer access a shared memory through the window. it's giving closure, it's giving moving on 😭🦋

heads up! this method may not be implemented — it's hardware specific, because of course the memory windows interface varies per hardware. so if it's not there, that's a hardware thing, not a you thing 💅

🔥 RETURN 🔥

Zero on success 🎉 otherwise an error number, and honestly? same.
