pseries_eeh_init_edev(9)

💖 NAME 💖

okay so bestie, this is the pseries_eeh_init_edev(9) manual page — the kernel API function that initialises the eeh_dev and eeh_pe for a pci_dn. It’s giving serious powerpc PCI energy, no cap. ✨

🌸 SYNOPSIS 🌸

void pseries_eeh_init_edev (struct pci_dn *pdn );

🎀 ARGUMENTS 🎀

• pdn — PCI device node. That’s the one and only arg, bestie. 🫶

🦋 DESCRIPTION 🦋

So picture this: when we discover a new PCI device via the device-tree, we create a corresponding pci_dn, and we allocate — but don’t initialise — an eeh_dev. 👀

This function takes care of the initialisation and inserts the eeh_dev into the correct eeh_pe. And if no eeh_pe exists? We’ll allocate one. Periodt. 💅

Basically: the eeh_dev allocation already happened, and pseries_eeh_init_edev() is the main character that finishes the job — initialise, insert, and if needed, make a fresh eeh_pe. It’s giving setup-and-slot-in energy, fr fr. 🔥
