ice_dpll_ou...requency_set(9)

💅 ice_dpll_output_frequency_set — like, the output pin callback for setting frequency ✨

okay so this is a page straight out of the Kernel API Manual (yes, that's the manual name, we're fancy here 🎀) and it's about ice_dpll_output_frequency_set(9). Grab a snack, bestie, we're getting into it 💖

---

🌸 NAME

ice_dpll_output_frequency_set — the output pin callback that handles set frequency. That's literally the whole vibe. It's the thing that gets called when someone wants a pin's frequency changed 🦋

---

✨ SYNOPSIS

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

---

💜 ARGUMENTS

Six args, no skips, we love a full roster 👑

• pin — a pointer to a pin. yeah, that pin 🎀
• pin_priv — the private data pointer that got passed in when the pin was registered. it's giving "you left your stuff at my place" energy 🔥
• dpll — a pointer to the dpll ✨
• dpll_priv — the private data pointer passed on dpll registration. matching set with pin_priv, iykyk 🫶
• frequency — the frequency that's about to be set. like, u64, so it can go big 💀
• extack — error reporting. the little messenger that tells userspace what went wrong 😭

---

🦋 DESCRIPTION

It wraps the internal set frequency command on a pin. That's it, that's the function — a cute little wrapper doing its one job and doing it well 💅

---

🌈 CONTEXT

Heads up bestie: this calls a function which acquires pf->dplls.lock. so like, mind your locking manners, okay? 🔒

---

⭐ RETURN

• 0 — success! slay, the frequency got set 🎉
• negative — error: either the pin wasn't found, or it couldn't set it in hw. not iconic, but it happens 😭

okay this list is long bestie, but we do not skip entries in this house. every single one, in order, no cap 🫡
