💅 ice_dpll_pin_phase_adjust_get(9) — Kernel API Manual realness 💅

okay bestie, settle in, because we're reading a manpage from the Kernel API Manual, page ice_dpll_pi...e_adjust_get(9) (yes the title got truncated, she's mysterious like that ✨). it's giving "small callback, big responsibilities" and honestly? obsessed.

✨ NAME ✨

ice_dpll_pin_phase_adjust_get — the callback that goes and gets the pin phase adjust value. that's it, that's the gig 🎀

🦋 SYNOPSIS 🦋

int ice_dpll_pin_phase_adjust_get (const struct dpll_pin *pin , void
*pin_priv , const struct dpll_device *dpll , void *dpll_priv , s32
*phase_adjust , struct netlink_ext_ack *extack );

look at her. six arguments, zero chill. copy it exactly, no cap 💅

🌸 ARGUMENTS 🌸

  • pin — pointer to a pin 🧚 like, the actual pin we're talking about here
  • pin_priv — the private data pointer that got passed on pin registration (she's been holding onto it this whole time)
  • dpll — the registered dpll pointer
  • dpll_priv — the private data pointer that got passed on dpll registration, same energy as above but for the dpll
  • phase_adjust — on success this bad girl holds the pin phase_adjust value 👑 (yes, that's how you get the answer out)
  • extack — error reporting, aka where the sad news goes when something breaks 😭

💖 DESCRIPTION 💖

so this is a dpll subsystem callback — main character energy in the networking clock world fr fr. it's the handler for getting the phase adjust value of a pin. someone asks "hey what's the phase adjust on this pin", and this function is the one who answers. periodt 💅

🔥 CONTEXT 🔥

lowkey important: this one acquires pf->dplls.lock 💀 so like, be aware of the lock situation, bestie. no funny business.

⭐ RETURN ⭐

  • 0 — success 🎉 slay, we got the value
  • negative — error 😭 something went sideways, check that extack

iykyk 🫶 that's the entire extended universe right there.

anyway, that's the page, bestie. huge shoutout to the source at ./drivers/net/ethernet/intel/ice, dated October 2026 — she's from the future and she's still explaining phase adjust values to us. iconic behavior, honestly 💜✨
