💅 ice_dpll_init_ref_sync_inputs — NAME ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is ice_dpll_in..._sync_inputs(9). the actual function name is ice_dpll_init_ref_sync_inputs and its whole thing is: initialize reference sync pin pairs 🎀

🌸 SYNOPSIS 🌸

int ice_dpll_init_ref_sync_inputs (struct ice_pf *pf );

like… that's it. that's the whole vibe. one arg, one int coming back. slay 🫶

🦋 ARGUMENTS 🦋

  • pf — the pf private structure. that's your whole context babe, hand it over 💜

✨ DESCRIPTION ✨

so what does it do? it reads the DPLL TLV capabilities and then initializes the reference sync pin pairs over in the dpll subsystem. literally that's the job. read the caps, set up the pins, done. no cap 💅

🔥 RETURN 🔥

  • 0 — success 🎉 or nothing to do (and "nothing to do" here means there are no ref-sync tlv present, so don't come for her, she did her best)
  • negative — AQ failure 😭 that's the sad path, it's giving error
fr fr check that return value. negative = something went sideways with the AQ and you're gonna have a bad time.

👑 SEE ALSO 👑

the source of truth is the kernel file ./drivers/net/ethernet/intel/ice/ice_dpll.c — and bestie there are so many siblings, i'm listing every single one because i would never do them dirty like that 🧚

and that's the whole page bestie 💖 this one lives in ./drivers/net/ethernet/intel/ice, dated October 2026, and it's ice_dpll_in..._sync_inputs(9) forever and always. mwah 🎀✨
