ibm_slot_from_id(9)

okay bestie, welcome to ibm_slot_from_id(9) from the Kernel API Manual — it’s literally a workaround for bad ibm hardware, and it has main-character energy for such a tiny helper 💅✨

🌸 NAME 🌸

ibm_slot_from_id — workaround for bad ibm hardware 🫶

✨ SYNOPSIS ✨

union apci_descriptor * ibm_slot_from_id (int id );

🎀 ARGUMENTS 🎀

• id — the slot number that linux refers to the slot by. Like, this is the number Linux uses to point at the slot, no cap.

🦋 DESCRIPTION 🦋

Okay so this method returns the aCPI slot descriptor corresponding to the Linux slot number. That descriptor has info about the aPCI slot id and the attention status — it’s giving very “important little descriptor” energy, fr fr.

bestie, real talk: this descriptor must be freed using kfree when done. No cap, don’t ghost it, don’t leak it — free it when you’re done 💀
