pcie_port_device_resume(9)

💅 pcie_port_device_resume(9) 💅

okay bestie, so this is a page straight out of the Kernel API Manual (that's the manual name, no cap) and it's all about pcie_port_device_resume. It lives under the name pcie_port_device_resume(9), which is the section 9 vibe — kernel internals, iykyk. 🧚

---

✨ NAME ✨

pcie_port_device_resume — resume the port services that are associated with a PCIe port 🦋

Like, the port woke up from its little nap and all its services are like "omg we're back." Main character energy fr.

---

🔥 SYNOPSIS 🔥

int pcie_port_device_resume (struct device *dev );

That's int coming back at you (the return type, bestie), and one single argument. Clean. Minimal. Iconic. 👑

---

🎀 ARGUMENTS 🎀

• dev — the PCI Express port you want to handle, like, that's the one. The port. The device. Your girl. Pass it in and let the function do its thing. 💖

---

🌈 SEE ALSO 🌈

okay this is the part where the kernel says "go read literally everything else too" and honestly? valid. Here's the whole squad:

• release_pcie_device(9)
• pcie_port_enable_irq_vec(9)
• pcie_init_service_irqs(9)
• get_port_device_capability(9)
• pcie_device_init(9)
• pcie_port_device_register(9)
• pcie_port_device_suspend(9)
• pcie_port_device_runtime_suspend(9)
• pcie_port_device_runtime_resume(9)
• pcie_port_find_device(9)
• pcie_port_device_remove(9)
• pcie_port_bus_probe(9)
• pcie_port_bus_remove(9)
• pcie_port_service_register(9)
• pcie_port_service_unregister(9)

and they all live in the kernel file ./drivers/pci/pcie/portdrv.c, so that's your reading list. 🫶

ngl bestie, the resume trio is right there — pcie_port_device_suspend(9), pcie_port_device_runtime_suspend(9) and pcie_port_device_runtime_resume(9) — so if you're doing suspend/resume brainrot, go click through all of them. 💀
