💅 ice_dpll_pin_state_update(9) 💅

okay so this is straight out of the Kernel API Manual, bestie — like, the actual kernel docs, not some random blog post. sit down, grab a strawberry, we're learning ✨

🌸 NAME 🌸

ice_dpll_pin_state_update — bestie, it updates the pin's state. that's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

int ice_dpll_pin_state_update (struct ice_pf *pf , struct ice_dpll_pin
*pin , enum ice_dpll_pin_type pin_type , struct netlink_ext_ack *extack
);

like yes, it returns an int, and yes, that argument list is a whole friend group 🫶

👑 ARGUMENTS 👑

  • pf — the private board struct. it's giving "main character data structure energy", fr fr 💅
  • pin — the structure with pin attributes that are gonna get updated. it's getting a glow-up ✨
  • pin_type — which type of pin we're updating rn. iykyk 🦋
  • extack — error reporting. the one who tells you what went wrong, lowkey essential 😭

💖 DESCRIPTION 💖

so here's the tea: this figures out the pin's current state and its frequency, and then updates the struct that's holding all the pin info. no cap, that's it, that's the function 🎀

and because the details matter (they always do, bestie), here's the split: for input pins, states are separated for each dpll. for rclk pins, states are separated for each parent. like, different pins, different state groupings — periodt. 🔥

🔒 CONTEXT 🔒

called under pf->dplls.lock. so like… it's already holding the lock, don't go grabbing it again, that's not the move 🙈💀

⭐ RETURN ⭐

  • 0 — OK. slay, it worked, we ate 💅✨
  • negative — error. not the vibe, but at least you know 😭

🌈 SEE ALSO 🌈

okay this list is long long, but every single one of these is invited to the party, no plus-ones skipped 🫶

it all lives in the Kernel file ./drivers/net/ethernet/intel/ice/ice_dpll.c, plus this enum:

and that's the whole page, bestie 💜

this masterpiece lives at ./drivers/net/ethernet/intel/ice, it's dated October 2026, and it goes by ice_dpll_pin_state_update(9). mwah, go read the source, ily 🧚💖
