✨ e1000e_phc_get_syncdevicetime ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one is a callback — yes, a callback, main character energy fr — living in the e1000e driver, and it's the little guy the timekeeping code calls when it wants to know what time it is on both sides at once. 🕰️✨

---

🌸 NAME 🌸

e1000e_phc_get_syncdevicetime — the callback you hand to the timekeeping code so it can read the system/device registers. that's it, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

int e1000e_phc_get_syncdevicetime (ktime_t *device , struct system_counterval_t *system , void *ctx );

---

🎀 ARGUMENTS 🎀

• device — the current device time, no cap. this is where the device's clock value goes 🫶
• system — the system counter value read synchronously with device time. the whole point is that these two get read together, iykyk ⏱️
• ctx — the context provided by timekeeping code. it's not yours, it's handed to you, just pass it along bestie 🙈

---

⭐ DESCRIPTION ⭐

so what does it actually do? it reads the device clock and the system (ART) clock simultaneously — like, at the same time, together, holding hands 🤝 — and then returns the corrected clock values in ns (nanoseconds, the tiny tiny units 💫).

that's the tea. simultaneous read, corrected values, nanoseconds. periodt. 👑
