🌸 e1000e_update_phy_task(9) — the Kernel API Manual, bestie edition 🌸

Okay so we're in the <pink>Kernel API Manual</pink> today, and the function we're stanning is e1000e_update_phy_task 💅 yes, the (9) is part of the name, that's just how kernel docs roll, iykyk.

✨ NAME ✨

e1000e_update_phy_task — the work thread that updates the phy 🧚‍♀️ like, that's literally her whole job.

🦋 SYNOPSIS 🦋

void e1000e_update_phy_task (struct work_struct *work );

🎀 ARGUMENTS 🎀

  • work — pointer to our work struct 🫶 that's it, that's the whole argument, she's lowkey not complicated.

💖 DESCRIPTION 💖

so here's the tea, bestie ☕ this worker thread exists because we must acquire a semaphore to read the phy, which we could msleep while waiting for it, and we can't msleep in a timer. no cap, that's the entire reason she was born — timer context says no sleeping, so the work thread handles it instead 🔥

🌈 SEE ALSO 🌈

Kernel file ./drivers/net/ethernet/intel/e1000e/netdev.c — the source file, go read her 📖

and now the whole friend group, in order, every single one, because we do not leave anyone out at this party 💜

and that's the page, bestie 🫶

shoutout to the source, <purple>./drivers/net/ethernet/intel/e...</purple>, dated <mint>October 2026</mint> — that's the version and date, and yes I truncated it exactly like the original did, don't come for me 🙈

stay hydrated, don't msleep in a timer, and slay your phy reads 💅✨ 🍓
