ocxl_function_close(9)

okay so bestie, we're looking at ocxl_function_close(9) today — straight out of the Kernel API Manual, and it's literally the "bye bye" button for an OpenCAPI function 💅✨

🎀 NAME 🎀

ocxl_function_close — close an OpenCAPI function. It frees any AFUs you previously retrieved from the function, and detaches the associated contexts. Lowkey important: those contexts have to be freed by you, the caller. Not the function's job, yours 🫶

✨ SYNOPSIS ✨

void ocxl_function_close (struct ocxl_fn *fn );

🌸 ARGUMENTS 🌸

• fn — the OpenCAPI function you're closing. that's the one. the main character of this whole operation 👑

bestie reminder 💀 — the AFUs get freed for you, the contexts do not. free them yourself or they're just gonna sit there. no cap.
