💖 isa_bridge_find_early(9) 💖

okay so bestie, welcome to isa_bridge_find_early(9) from the Kernel API Manual ✨ this one is short and sweet: its whole job is to find and map the ISA IO space early, before main PCI discovery. No cap. It’s optionally called by the arch code when adding PCI PHBs, so the arch code can get early access to ISA IO ports 🫶.

🦋 SYNOPSIS 🦋
