e1000_id_led_init_pchlan(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to e1000_id_led_init_pchlan(9) from the Kernel API Manual — this is the LED-config page and it's lowkey iconic 💅✨

🌸 NAME 🌸

e1000_id_led_init_pchlan — store LED configurations 💡🎀

✨ SYNOPSIS ✨

the signature is giving exactly this, no edits:

s32 e1000_id_led_init_pchlan (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure 🫶

💖 DESCRIPTION 💖

okay so here's the tea: PCH does not control LEDs via the LEDCTL register. nope! it uses the PHY LED configuration register instead 💡✨

and PCH also does not have an "always on" or "always off" mode, which lowkey complicates the ID feature 😭💅

so instead of using the "on" mode to indicate in ledctl_mode2 the LEDs to use for ID (see e1000e_id_led_init_generic), you use link_up mode 👑✨

and bestie, the LEDs will still ID on request if there is no link, based on the logic in e1000_led_[on|off]_pchlan. periodt 💅🔥
