pci_dpc_recovered(9)

🦋 pci_dpc_recovered(9) 🦋

okay so bestie, you're in the Kernel API Manual and this is the page for pci_dpc_recovered — literally the little function that tells you whether DPC fired and then, like, actually got its life together 💅

---

✨ NAME ✨

pci_dpc_recovered — whether DPC triggered and has recovered successfully 👑

---

🌸 SYNOPSIS 🌸

bool pci_dpc_recovered (struct pci_dev *pdev );

---

🎀 ARGUMENTS 🎀

• pdev — a PCI device 🫶 (yes that's the whole description, she's lowkey mysterious)

---

💖 DESCRIPTION 💖

So here's the vibe: this returns true if DPC was triggered for pdev and it has recovered successfully. periodt ✨

If the recovery hasn't completed yet? It waits for it. no cutting the line, no skipping ahead, we sit there until it's done 😭

And why do we care? Because it's called from the PCIe hotplug driver, so it can recognize and ignore Link Down/Up events caused by DPC. it's giving "oh that? that's just DPC, ignore her" 🙈💀

🔥 SEE ALSO 🔥

• Kernel file ./drivers/pci/pcie/dpc.c — go read the source, iykyk 📖
