💖 cavium_ptp_settime(9) 💖

okay so real talk, bestie — you're reading a page out of the Kernel API Manual, and it's all about cavium_ptp_settime. she's a little function with one job and she does it. let's get into it ✨

---

🌸 NAME 🌸

cavium_ptp_settime — Set hardware clock time. Reset adjustment 🕰️✨

like, she sets the hardware clock and resets the adjustment. two things. one function. main character energy fr fr 💅

---

🎀 SYNOPSIS 🎀

int cavium_ptp_settime (struct ptp_clock_info *ptp_info , const struct timespec64 *ts );

look at her go 🫶 returns an int, takes two pointers, zero drama.

---

🦋 ARGUMENTS 🦋

• ptp_info — PTP clock info 👑 this is the clock's little info card, she needs it to know who she is
• ts — timespec ⏱️ the actual time value you're handing over, no cap

ngl both of these are pointers and neither of them is optional in spirit, so don't be out here passing nonsense 🙈
