💤 igb_ptp_suspend — the igb_ptp_suspend(9) manual page, bestie edition

okay so this is the kernel API manual page for igb_ptp_suspend, from the <pink>9</pink> section (that's kernel API docs, iykyk), and honestly? It's a little one but it's a crucial one. Let's get into it 🫶

✨ NAME ✨

igb_ptp_suspend — Disable PTP work items and prepare for suspend 💤

Like the name literally says the whole thing. It turns off the PTP work stuff and gets the device ready to go night-night. No cap.

🦋 SYNOPSIS 🦋

void igb_ptp_suspend (struct igb_adapter *adapter );

That's it. That's the whole signature. Returns void, so it gives you nothing back except peace of mind ✨ (and honestly, sometimes that's enough).

🎀 ARGUMENTS 🎀

  • adapter — Board private structure. This is your board's own private little structure, the main character of the whole operation 👑

🌸 DESCRIPTION 🌸

Okay so here's what this function actually does, and it's giving responsible adult energy:

  • it stops the overflow check work 💅
  • it stops the PTP Tx timestamp work 🔥
  • and it prepares the device for OS suspend 😴

That's the whole vibe check. Everything's wrapped up, work items are cancelled, device is ready for the OS to hit that suspend. Periodt. 🎀

ngl this is one of those functions you don't think about until you have to think about it, and then you're very glad it exists 🙈
