emac_poll_controller(9)

💅 emac_poll_controller — a Kernel API Manual moment (section 9, bestie)

okay so welcome to the emac_poll_controller(9) page, she's short but she's iconic, and we're gonna get through her together 🎀

---

✨ NAME ✨

emac_poll_controller — the EMAC Poll controller function. that's it. that's her whole job title. lowkey the simplest NAME section on the whole system and honestly? respect. 👑

---

🌸 SYNOPSIS 🌸

void emac_poll_controller (struct net_device *ndev );

that's the whole signature, no cap — returns void, takes exactly one thing, and we're gonna talk about that thing right now 🦋

---

🧚 ARGUMENTS 🧚

• ndev — The DaVinci EMAC network adapter. that's your one and only input, bestie: a pointer to the actual network adapter, and she is specifically a DaVinci EMAC one. main character energy, but for network hardware 💖

---

🔥 DESCRIPTION 🔥

Polled functionality used by netconsole and others in non interrupt mode.

let me translate that vibe: this is the polled mode of doing things — like, instead of sitting around waiting for an interrupt to come knock on your door, you just keep checking yourself. and the crowd that shows up for that is netconsole plus other friends who live in non interrupt mode. so when interrupts are off the table, this is the function that carries the whole group chat 😭✨

ngl this description is short, but bestie, do not sleep on it — "non interrupt mode" is the whole point here, that's the vibe check that matters 💀
