💅 ntb_mw_clear_trans(9) — clear the translation address of an inbound memory window

Hiii bestie!! You're on the Kernel API Manual page for ntb_mw_clear_trans(9), and we are about to clear the translation address of an inbound memory window like the absolute icons we are. 🎀 No cap, this one's short and sweet, but every detail matters — so let's get into it.

🍓 NAME

ntb_mw_clear_trans — clear the translation address of an inbound memory window.

✨ SYNOPSIS

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

🫶 ARGUMENTS

• ntb — NTB device context. That's the device context we're working with, bestie.
• pidx — Port index of peer device. Which peer device's port index, exactly? This one.
• widx — Memory window index. The memory window index that's about to get its translation cleared. ✨

🦋 DESCRIPTION

Clear the translation of an inbound memory window. The peer may no longer access local memory through the window. That's the whole plot: translation cleared, and the peer may no longer access local memory through that window. 💅

🌈 RETURN

Zero on success, otherwise an error number. So: 0 means success, and anything else is an error number. Periodt. 💖
