get_slot_mapping(9)

🌸 NAME 🌸

okay so welcome to get_slot_mapping(9) from the Kernel API Manual, bestie 💖 this page is literally here to determine logical slot mapping for PCI device — yes, that's the whole vibe, and it ate ✨

✨ SYNOPSIS ✨

int get_slot_mapping (struct pci_bus *bus , u8 bus_num , u8 dev_num , u8
       *slot );

🎀 ARGUMENTS 🎀

• bus — pointer to the PCI bus structure, got it? 🫶
• bus_num — bus number of PCI device, no cap 🌈
• dev_num — device number of PCI device, periodt 💅
• slot — Pointer to u8 where slot number will be returned — that's where the answer lands, bestie 🎀

💅 DESCRIPTION 💅

okay so the big disclaimer: this won't work for more than one PCI-PCI bridge in a slot 😭 like, that's the caveat, bestie — no cap, it just won't.

Output: SUCCESS or FAILURE — those are literally the two outcomes, and yes you get one of them 💀✨
