ice_dpll_hw_input_prio_set(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_dpll_hw_input_prio_set — like, the Kernel API Manual page, bestie 💖

okay so picture this: you're deep in the kernel, you've got a DPLL, you've got pins, and you need the hardware itself to know which input actually matters. That's this function. Welcome to the Kernel API Manual entry for ice_dpll_hw_input_prio_set(9) — buckle up, it's giving "small function, big responsibilities" ✨

🌸 NAME 🌸

ice_dpll_hw_input_prio_set — set the input priority value in hardware 🎀 no cap, that's literally the whole job.

⭐ SYNOPSIS ⭐

int ice_dpll_hw_input_prio_set (struct ice_pf *pf , struct ice_dpll
*dpll , struct ice_dpll_pin *pin , const u32 prio , struct
netlink_ext_ack *extack );

🦋 ARGUMENTS 🦋

  • pf — the board private structure 🫶 your whole device's personal lore lives in here
  • dpll — the ice dpll pointer 💫 yes, that dpll
  • pin — the ice pin pointer 📍 the specific pin we're doing this to
  • prio — the priority value being set on a dpll 👑 a const u32, so treat it with respect
  • extack — error reporting 😭 because when things go wrong, someone's gotta tell the netlink girlies about it

💜 DESCRIPTION 💜

It's an internal wrapper for setting the priority in the hardware. That's it, that's the vibe — a neat little internal wrapper so the rest of the driver doesn't have to rawdog the hardware call directly 🔥

🔒 CONTEXT 🔒

Called under pf->dplls.lock. so like… the lock is held when you call this. Do not come in here uninvited, bestie 🙈

✨ RETURN ✨

  • 0 — success 🎉 slay, it worked
  • negative — failure 💀 it did not work, and it's telling you so

🌈 SEE ALSO 🌈

okay so this section is huge, and honestly? iconic. The whole ice_dpll cinematic universe lives in the kernel file ./drivers/net/ethernet/intel/ice/ice_dpll.c, plus enum ice_dpll_pin_type(9) and everyone else in the family 💅

fr fr, if you're setting a priority without peeking at ice_dpll_input_prio_get(9) and friends first, you're doing main character energy wrong 👑

that's the whole page, bestie 🎀 this lore drop lives in ./drivers/net/ethernet/intel/ice, dated October 2026, and it's the ice_dpll_hw_input_prio_set(9) girl herself — go set some priorities, you've got this 💖✨🦋
