pci_devs_phb_init_dynamic(9)

okay so this is pci_devs_phb_init_dynamic(9) from the Kernel API Manual, and it's giving “kernel internals but make it make sense” energy 🧚✨. No cap, we're keeping every detail.

🌸 NAME 🌸

pci_devs_phb_init_dynamic — setup pci devices under this PHB phb: pci-to-host bridge (top-level bridge connecting to cpu). That's the whole vibe: PHB is the top-level bridge connecting to the cpu, iykyk 🫶.

🛠️ SYNOPSIS 🛠️

void pci_devs_phb_init_dynamic (struct pci_controller *phb );

🎀 ARGUMENTS 🎀

• phb — the original page literally says -- undescribed -- here 😭. So no invented lore, bestie: that's all it gives us.

💖 DESCRIPTION 💖

This routine is called both during boot, (before the memory subsystem is set up, before kmalloc is valid 😭) and during the dynamic lpar operation of adding a PHB to a running system. So it shows up in both of those moments — that's the tea, periodt 💅.

👀 SEE ALSO 👀

• Kernel file ./arch/powerpc/kernel/pci_dn.c
