💖 idpf_ptp_set_dev_clk_time(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a little function with big "let me just set the clock real quick" energy, and honestly? iconic.

---

🌸 NAME 🌸

idpf_ptp_set_dev_clk_time — it sends the virtchnl set device time message 🕐💌 like it's dropping a very official text to the hardware being like "here's the time bestie, sync up"

---

🎀 SYNOPSIS 🎀

int idpf_ptp_set_dev_clk_time (struct idpf_adapter *adapter , u64 time );

---

🦋 ARGUMENTS 🦋

• adapter — the driver specific private structure 💅 this is the main character struct, the one holding all the driver's secrets
• time — the new time value ⏰ a u64, so it's a whole lot of time, no decimals needed

---

✨ DESCRIPTION ✨

So what it does is: send the virtchnl set time message 📨 so the clock's time actually gets set. that's it, that's the whole vibe. not me expecting some huge dramatic backstory 😭 it just sets the clock.

---

🔥 RETURN 🔥

• 0 on success 🎉 slay, everything worked
• -errno otherwise 💀 yeah, something went sideways and you get the usual negated errno treatment
