pseries_eeh...ev_recursive(9)

okay so bestie, welcome to the Kernel API Manual page for pseries_eeh...ev_recursive(9) ✨ — aka the little spotlight for pseries_eeh_init_edev_recursive. It’s short, it’s specific, and it’s giving “I have one job and I do it.” 💅

✨ NAME ✨

• pseries_eeh_init_edev_recursive — Enable EEH for the indicated device 🫶

📜 SYNOPSIS 📜

void pseries_eeh_init_edev_recursive (struct pci_dn *pdn );

🎀 ARGUMENTS 🎀

• pdn — the PCI device node 🦋

💖 DESCRIPTION 💖

This routine has one very specific job, and bestie, it is not optional: it must be used to perform EEH initialization for the indicated PCI device that was added after system boot (e.g. hotplug, dlpar). So if a device showed up post-boot and needs its EEH situation handled, this is the routine you use for it. Periodt. ✨
