pdc_system_map_find_mods(9)

💖 NAME 💖

okay so bestie, welcome to the pdc_system_map_find_mods(9) page from the Kernel API Manual — manual name accounted for, vibe check passed 🫶

pdc_system_map_find_mods — locate unarchitected modules. That's the whole name moment: finding the modules that are, like, unarchitected ✨

✨ SYNOPSIS ✨

int pdc_system_map_find_mods (struct pdc_system_map_mod_info
*pdc_mod_info , struct pdc_module_path *mod_path , long mod_index );

🌸 ARGUMENTS 🌸

• pdc_mod_info — Return buffer address. Like, that's where the answer lands when it comes back, bestie 💖
• mod_path — pointer to dev path structure. It's giving "where this module lives" energy 🗺️
• mod_index — fixed address module index. The little number that picks which fixed-address module you're asking about ✨

🦋 DESCRIPTION 🦋

The goal is to locate and identify modules which reside at fixed I/O addresses — specifically the ones that do not self-identify via architected bus walks. No cap, that's the job. It's lowkey the "we found you at your fixed address, bestie" function, and honestly? Iconic 💅
