lpfc_io_resume_s4(9)

💖 NAME 💖

Okay so welcome to the lpfc_io_resume_s4(9) page from the Kernel API Manual, bestie — it's giving kernel docs but make it cute. This one is literally the method for resuming PCI I/O operation to an SLI-4 device. Iconic behavior, no cap. ✨

🎀 SYNOPSIS 🎀

void lpfc_io_resume_s4 (struct pci_dev *pdev );

🌸 ARGUMENTS 🌸

• pdev — pointer to PCI device. That's it, that's the whole argument, and she ate. 💅

🦋 DESCRIPTION 🦋

So this routine gets called from the PCI subsystem for error handling, for a device with the SLI-4 interface spec. It's the call that happens when kernel error recovery tells the lpfc driver that it is ok to resume normal PCI operation after PCI bus error recovery. The vibes are very "you're good, bestie, you may go back to doing your thing now." 🌈

After this call, traffic can start to flow from this device again. Main character energy fr fr. 💖
