💖 phy_notify_state(9) 💖

okay so this is <hotpink>phy_notify_state</hotpink> from the Kernel API Manual, section 9 — yes bestie, section 9, the ~spicy driver-internals section. it's a little function whose whole job is telling your PHY "hey girl, something changed" ✨

🌸 NAME 🌸

phy_notify_state — phy state notification. that's it, that's the whole pitch. it notifies. it's about state. iconic behaviour honestly 💅

🦋 SYNOPSIS 🦋

int phy_notify_state (struct phy *phy , union phy_notify state );

look at her. returns an int, takes a struct phy * and a union phy_notify. clean, simple, no cap 🫶

🎀 ARGUMENTS 🎀

  • phy — the PHY returned by phy_get. like, the actual PHY object you already grabbed, not a fresh one. don't go making your own, that's not the vibe 🙈
  • state — the PHY state. it's a union phy_notify, so it's carrying the state info for you. this is the "what's the tea" parameter 🍓

⭐ DESCRIPTION ⭐

so basically: you call this to notify the PHY of a state transition. it's used to notify and configure the PHY accordingly — like, you tell it what just went down, and it sorts itself out to match. it's giving "texting your bestie the update and she immediately adjusts the plans" energy 💖

🌈 RETURN 🌈

  • 0 if successful 😌✨
  • a negative error code otherwise 😭 — so like, check it. fr fr. don't just ignore the return value, that's not main character energy, that's side-quest-failure energy 💀

👑 SEE ALSO 👑

everything else in the PHY cinematic universe, and also the kernel file ./drivers/phy/phy-core.c — that's where the lore lives, iykyk 🔥

like, the whole friend group 🫶 go read them, they're all slay in their own way.

and that's the page, bestie!! 🧚 this little gem lives under ./drivers/phy and the version stamp on it says October 2026 — so yeah, she's from the future, we stan a forward-thinking manpage 💜🎀
