ice_dpll_sw...requency_get(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

ice_dpll_sw_pin_frequency_get — the callback that goes and gets the frequency of a SW pin. Like, it fetches the number. That's the whole gig. 🎀

So this page lives in the Kernel API Manual, bestie, and it's all about one little callback in the Intel ice driver's DPLL corner of the world. Let's get into it. ✨

🌸 SYNOPSIS 🌸

int ice_dpll_sw_pin_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 );

Six arguments, one int coming back out. No cap. 💜

🦋 ARGUMENTS 🦋

Okay so every single one of these, in order, no skipping:

  • pin — pointer to a pin. Just a pin. Hi pin. 👋
  • pin_priv — the private data pointer that got passed on pin registration. It's the pin's lil secret stash. 🙈
  • dpll — pointer to dpll. Yep. That one. 💫
  • dpll_priv — the private data pointer that got passed on dpll registration. Same vibe, different struct. 🫶
  • frequency — on success this holds the pin's frequency. This is the good stuff, the actual answer. ✨
  • extack — error reporting. When things go sideways, this is who you tell. 😭

🧚 DESCRIPTION 🧚

It calls the get frequency command for the corresponding active input/output. That's it, that's the description. Short, sweet, gets the number. 🔥

👑 CONTEXT 👑

Little heads-up, bestie — this one calls a function which acquires and releases pf->dplls.lock. So like, the lock is handled for you, but also, the lock is happening. Know that. 💀

🌈 RETURN 🌈

  • 0 — success 🎉 slay
  • negative — error, pin not active or couldn't get from hw 😔
So real talk: if you get a negative number back, either the pin wasn't active or the hardware just wouldn't cough up the frequency. Not your fault, but also, do handle it.

⭐ SEE ALSO ⭐

Genuinely the longest list I've ever seen and I'm obsessed. It lives in the kernel file ./drivers/net/ethernet/intel/ice/ice_dpll.c 🍓, and also there's enum... and then all of these icons:

Like I said. Iconic. Periodt. 💅

And that's the whole page, bestie! 🫶 This lil masterpiece comes from ./drivers/net/ethernet/intel/ice, dated October 2026, and it's filed under ice_dpll_sw...requency_get(9) in the Kernel API Manual. Go forth and get those frequencies. 💖✨🎀
