💅 ice_dpll_update_state(9) — Kernel API Manual ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is ice_dpll_update_state(9). she's a function, she's a whole vibe, and honestly? she just wants the dpll state to be correct. let's get into it 🫶

🌸 NAME 🌸

ice_dpll_update_state — update dpll state. that's it, that's the tweet. short, sweet, iconic ✨

🦋 SYNOPSIS 🦋

int ice_dpll_update_state (struct ice_pf *pf , struct ice_dpll *d , bool
init );

literally just three args and a return type, no cap. keep reading for the tea on each one 👇

🎀 ARGUMENTS 🎀

  • pf — the pf private structure 💖 (her private business, respectfully)
  • d — pointer to the queried dpll device 🎯 the one we're asking questions to
  • init — set this if the function is called on initialization of ice dpll 🌱 like, the first-time setup moment

⭐ DESCRIPTION ⭐

so what does she do? she polls the current state of dpll from hw and updates the ice_dpll struct with it. that's the whole job. go get the hw truth, write it into the struct, slay 🔥

👑 CONTEXT 👑

called by kworker under pf->dplls.lock 🔒 — yes bestie, there's a lock, respect the lock, do not be weird about the lock. periodt.

💀 RETURN 💀

  • 0 — success 🎉 we ate
  • negative — AQ failure 😭 it's giving error, but at least it's informative

🌈 SEE ALSO 🌈

okay this is the part where I need you to stay with me, because the list is long, and I mean gorgeous-long, main-character-long. no skipping, we're reading all of it 🙈

kernel file ./drivers/net/ethernet/intel/ice/ice_dpll.c, plus:

like… a hundred-plus little functions all holding hands in a linked list of friendship 🧚💜 every single one of them is here, I checked, I would never do you dirty like that.

reminder bestie: this one's locked under pf->dplls.lock and runs from a kworker — respect the context or the kernel will simply not be cute about it 💅
