💅 ice_dpll_init_direct_pins — Kernel API Manual, bestie edition

okay so bestie. this is ice_dpll_init_direct_pins(9) from the Kernel API Manual, and it is literally the glow-up function for the Intel ice driver's DPLL pins. she's giving "make the direct pins exist in the dpll subsystem" main character energy and we're gonna walk through her whole vibe. 🎀

✨ NAME

ice_dpll_init_direct_pins — initialize direct pins 💅

like, that's it. that's the whole job. initialize. direct pins. slay.

🦋 SYNOPSIS

int ice_dpll_init_direct_pins (struct ice_pf *pf , bool cgu , struct
ice_dpll_pin *pins , int start_idx , int count , const struct
dpll_pin_ops *ops , struct dpll_device *first , struct dpll_device
*second );

eight whole arguments, no cap. she's high-maintenance but worth it. 🔥

🌸 ARGUMENTS

  • pf — board private structure. the NIC's personal diary, basically 🫶
  • cgu — if cgu is present and controlled by this NIC. yes/no energy 💀
  • pins — pointer to the pins array. the whole friend group 🌈
  • start_idx — on which index shall allocation start in dpll subsystem 📍
  • count — number of pins. how many besties we bringing ✨
  • ops — callback ops registered with the pins. the little behavior menu 🎀
  • first — dpll device pointer 🌟
  • second — dpll device pointer (yes, a second one. she has two hands 🫶🫶)

💜 DESCRIPTION

okay so here's the tea. she allocates directly connected pins of a given array in the dpll subsystem. that's the whole assignment, no notes. 💅

and if cgu is owned, she registers the allocated pins with the given dplls. that's it. that's the function. iykyk. 🧚

👑 RETURN

  • ✅ 0 — success. ate. 🔥
  • ❌ negative — registration failure reason. not slay, but at least she tells you why 😭

okay bestie this list is long long, so buckle up, we're going shopping 🛍️ — starting with the kernel file herself:

bestie that was a lot of cross-references and we got through all of them together. proud of us fr fr 🫶
