💖 eeh_dev_open(9) — Kernel API Manual 💖

okay bestie, welcome to the eeh_dev_open(9) page ✨ this is the kernel API manual moment where we bump a count for pass through devices tied to a PE, and every single detail is staying right here, no cap 🫶

🌸 NAME 🌸

eeh_dev_open — Increase count of pass through devices for PE 👑

✨ SYNOPSIS ✨

int eeh_dev_open (struct pci_dev *pdev );

🎀 ARGUMENTS 🎀

• pdev — PCI device 💻

🦋 DESCRIPTION 🦋

Increase count of passed through devices for the indicated PE. In the result, the EEH errors detected on the PE won't be reported. The PE owner will be responsible for detection and recovery. 👀

So the whole point is: the count goes up, EEH errors on that PE won't be reported, and the PE owner is the one doing detection and recovery. That's it, bestie 💅
