mlx4_en_phc_settime(9)

💖 NAME 💖

Okay bestie, this is mlx4_en_phc_settime(9) from the Kernel API Manual — the page about setting the current time on the hardware clock. It’s giving tiny-but-powerful timekeeper energy 👑⏰

✨ SYNOPSIS ✨

int mlx4_en_phc_settime (struct ptp_clock_info *ptp , const struct
       timespec64 *ts );

🎀 ARGUMENTS 🎀

• ptp — the ptp clock structure. That’s the main character here 💅
• ts — a timespec containing the new time for the cycle counter. Fresh time, freshly delivered 🕰️✨

🦋 DESCRIPTION 🦋

So the move is: reset the timecounter so it uses a new base value instead of the kernel wall timer value. That’s literally the whole vibe — new base value, not the kernel wall timer value. No cap, that’s the description fr fr 🌸
