💅 cxgb4_ptp_settime — like, the Kernel API Manual page, bestie 🎀

okay so first things first: this whole thing lives in the Kernel API Manual (section 9), and the star of the show is cxgb4_ptp_settime(9). she sets the current time on the hardware clock. that's the vibe. ✨

✨ NAME ✨

cxgb4_ptp_settime — Set the current time on the hardware clock 🕰️

---

🌸 SYNOPSIS 🌸

int cxgb4_ptp_settime (struct ptp_clock_info *ptp , const struct
       timespec64 *ts );

like yes that's the whole signature, no cap 💅

---

🎀 ARGUMENTS 🎀

• ptp — the ptp clock structure. that's her. the main character 🫶
• ts — a timespec containing the new time for the cycle counter ⏱️

---

🦋 DESCRIPTION 🦋

okay so what she does is: reset value to new base value instead of the kernel wall timer value. literally that. she does not care about the kernel wall timer, she's doing her own thing. iconic behavior honestly 💀
