i40e_ptp_enable_pin(9)

💅 i40e_ptp_enable_pin — like, the manual page, bestie

okay so real talk: this is the i40e_ptp_enable_pin(9) page from the Kernel API Manual, and it's genuinely the shortest little icon in the i40e PTP saga, so we're gonna get through it together, no stress 🫶

✨ NAME ✨

i40e_ptp_enable_pin — bestie, it enables PINs. that's it. that's the whole vibe. 🔥

---

🌸 SYNOPSIS 🌸

int i40e_ptp_enable_pin (struct i40e_pf *pf , unsigned int chan , enum
ptp_pin_function func , int on );

look at her go, she's gorgeous, she returns an int 👑

---

🎀 ARGUMENTS 🎀

• pf — the private board structure 💖 like, the whole personality of the board lives in here
• chan — the channel 🌈 which one are we talking about, babes
• func — the PIN function 🦋 this is an enum ptp_pin_function, so it's giving very specific-choices energy
• on — the state ⭐ on or... not on. the duality of woman

---

🧚 DESCRIPTION 🧚

so the tea is: this function enables PTP pins for an external clock source. 🕰️✨ that's literally the job. main character behavior, no notes.

it returns 0 on success, or an error code on failure — so like, check it, bestie, don't just ghost the return value 😭

🔥 SEE ALSO 🔥

okay this list is long, but I refuse to skip a single one because every one of these deserves her moment. go read all of them, iykyk 💜

the kernel file herself: ./drivers/net/ethernet/intel/i40e/i40e_ptp.c

and now, the full roster, in the exact order the manpage gives them, because we do not shuffle the lineup:

and yes, i40_ptp_reset_timing_events(9) really does have that name up there — one e short of the party. don't @ me, that's literally what the page says, we're just reporting the facts 💀
