stmmac_init_timestamping(9)

💖 NAME 💖

okay so this is stmmac_init_timestamping(9), straight from the Kernel API Manual, and it’s giving “tiny but important timestamping setup moment” energy ✨

stmmac_init_timestamping — initialise timestamping. that’s the whole vibe, and honestly? iconic. 💅

---

✨ SYNOPSIS ✨

int stmmac_init_timestamping (struct stmmac_priv *priv );

---

🎀 ARGUMENTS 🎀

• priv — the driver private structure. it’s the little bag of driver state that gets passed in, and yes bestie you gotta have it. 🫶

---

🦋 DESCRIPTION 🦋

okay so the mission here is to verify if the HW supports PTPv1 or PTPv2. how do we do that? by looking at the HW cap. register, bestie. no cap 🧢 — that’s literally the check.

and that’s not all: this function also registers the ptp driver. so it’s doing the support vibe check and the registration moment. periodt. 💖
