i40e_ptp_set_pin_hw(9)

💅 i40e_ptp_set_pin_hw(9)

okay so bestie, welcome to the Kernel API Manual ✨ — today's episode is all about i40e_ptp_set_pin_hw(9), and honestly? she's a tiny little function but she does exactly one job and she does it flawlessly. no cap.

---

✨ NAME ✨

i40e_ptp_set_pin_hw — set the HW GPIO pin 🎀

like… that's it. that's the whole vibe. set the pin. slay.

---

🦋 SYNOPSIS 🦋

void i40e_ptp_set_pin_hw (struct i40e_hw *hw , unsigned int pin , enum
i40e_ptp_gpio_pin_state state );

she takes three things and returns nothing — a true void queen, void is literally her whole personality 💀

---

🌸 ARGUMENTS 🌸

• hw — pointer to the hardware structure. the main character here tbh, you gotta hand her the hardware or nothing happens 🫶
• pin — pin index. which pin are we talking about, bestie? specify. 🔥
• state — pin state. what state is that pin in. this is the whole point of the operation ngl.

---

💜 DESCRIPTION 💜

Set the status of the GPIO pin for external clock handling ⏰✨

that's literally the entire description, and honestly? iconic. she doesn't over-explain. she sets the GPIO pin status so external clock handling can do its thing, and then she leaves. no drama, no notes 👑

okay that's the page!! mwah 💋 this one came from ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's filed under i40e_ptp_set_pin_hw(9) — periodt. go set some pins bestie, ily 🧚💜
