ice_dpll_ou...requency_get(9)

✨ ice_dpll_output_frequency_get — the getter that spills the tea on your pin's frequency ✨

okay so bestie, this is a Kernel API Manual page, section 9 of the manual, and the star of the show is ice_dpll_output_frequency_get — the output pin callback for get frequency. it's in the kernel file ./drivers/net/ethernet/intel/ice/ice_dpll.c and honestly? she's giving "small function, big responsibilities" 💅

---

🌸 NAME 🌸

ice_dpll_output_frequency_get — output pin callback for get frequency. that's it, that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

int ice_dpll_output_frequency_get (const struct dpll_pin *pin , void
*pin_priv , const struct dpll_device *dpll , void *dpll_priv , u64
*frequency , struct netlink_ext_ack *extack );

---

💖 ARGUMENTS 💖

like six whole parameters, no cap, let's go through them one by one:

• pin — pointer to a pin 🎯 like, the pin in question, the main character herself
• pin_priv — the private data pointer that got passed on pin registration. she's been waiting there this whole time
• dpll — pointer to dpll. yes, another pointer, we love a pointer
• dpll_priv — the private data pointer that got passed on dpll registration. the dpll cousin of pin_priv fr fr
• frequency — on success this one holds the pin's frequency ✨ the whole point tbh
• extack — error reporting. the messenger when things go sideways 😭

---

🌈 DESCRIPTION 🌈

she wraps the internal get frequency command of a pin. that's the whole assignment. a dainty little wrapper, doing her job, unbothered 🫶

---

🔥 CONTEXT 🔥

heads up bestie: this one calls a function which acquires pf->dplls.lock — so mind your locking, she's locking things in there 👑

---

⭐ RETURN ⭐

• 0 — success, we ate 💅
• negative — error: pin not found, or it couldn't get from hw 💀 (yes, both of those, it's an either/or situation)
