igc_io_resume(9)

✨ igc_io_resume(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is the page for igc_io_resume, and it is literally the "we're so back" moment of the whole error-recovery saga 🎀

🌸 NAME 🌸

igc_io_resume — the callback that gets called when traffic can start to flow again 💅

🦋 SYNOPSIS 🦋

void igc_io_resume (struct pci_dev *pdev );

💖 ARGUMENTS 💖

• pdev — pointer to the PCI device 🫶 that's doing the whole "I'm fine now actually" thing.

👑 DESCRIPTION 👑

So here's the vibe: this callback gets called when the error recovery driver tells us that it's OK to resume normal operation ✨. Like, permission granted, go live your life, move those packets, main character energy only 🌈.

And plot twist — the implementation resembles the second-half of the __igc_resume routine. Not the whole thing. The second half. iykyk 🧚

ngl that's the entire page. it's a short one. but every single reference below is staying, because we do not skip lore on this blog 💀
