eeh_reset_device(9)

💅 eeh_reset_device(9) 💅

okay bestie, this page is straight out of the Kernel API Manual, and it's all about actually resetting a PCI slot. no cap, it's a short one, but it matters. 🫶

---

🌸 NAME 🌸

eeh_reset_device — perform the actual reset of a PCI slot, periodt. ✨

---

🦋 SYNOPSIS 🦋

int eeh_reset_device (struct eeh_pe *pe , struct pci_bus *bus , struct eeh_rmv_data *rmv_data , bool driver_eeh_aware );

---

🎀 ARGUMENTS 🎀

• pe — the EEH PE. that's the whole vibe of what you're resetting. 💖
• bus — the PCI bus corresponding to the isolcated slot.
• rmv_data — optional, bestie. it's a list to record removed devices.
• driver_eeh_aware — answers the question: does the device's driver provide EEH support? 👀

---

🌈 DESCRIPTION 🌈

okay so this routine is literally the one you must call to do the reset on the indicated PE. no skipping it, no vibes-based workaround.

during the reset, udev might be invoked because those affected PCI devices will be removed and then added. so yeah, expect a little device-list shuffle. 🔥
