e1000_led_on(9)

💡 e1000_led_on(9) — the Kernel API Manual era ✨

ok so bestie, we're in the Kernel API Manual today and this one is genuinely so tiny it's giving palate cleanser 🫶 it's one function, three sections, and then a whole wall of SEE ALSO that you're gonna need a snack for. buckle up 💅

🌸 NAME

e1000_led_on — turns on the software controllable LED 💡✨

that's it. that's the whole job. she turns the LED on. main character energy, minimal lore, we respect it.

---

🦋 SYNOPSIS

s32 e1000_led_on (struct e1000_hw *hw );

look at her, so neat, so compact 🎀 verbatim, no notes.

---

🍓 ARGUMENTS

• hw — struct containing variables accessed by shared code. like, the whole e1000_hw struct, shared-code-access kind of situation, you get it 🫶

quick vibe check: e1000_led_off(9) is right there in the list too, so if you ever need the opposite energy, she exists 💅

aaand that's the page, bestie 🎀 take a bow, you learned a whole LED function 🌸 before you go — this cutie came from the source ./drivers/net/ethernet/intel/e... and she's dated October 2026, so go forth and glow ✨💜
