hiii bestie, welcome to the Kernel API Manual page for eeh_probe_device — the routine that handles EEH initialization for the indicated pci device. it's giving kernel plumbing, but make it cute ✨

✨ NAME ✨

eeh_probe_device — Perform EEH initialization for the indicated pci device 💖

🌸 SYNOPSIS 🌸

okay so the signature is literally:

void eeh_probe_device (struct pci_dev *dev );

🎀 ARGUMENTS 🎀

• dev — pci device for which to set up EEH 🫶

💅 DESCRIPTION 💅

okay so listen: this routine must be used to complete EEH initialization for PCI devices that were added after system boot — yes, we're talking e.g. hotplug, dlpar, that whole late-arrival situation 😭. if a PCI device showed up post-boot, this is the completion step, no cap ✨.
