💅 e1000e_igp3_phy_powerdown_workaround_ich8lan(9) — Kernel API Manual

okay so bestie, welcome to the Kernel API Manual ✨ you found the page for e1000e_igp3_phy_powerdown_workaround_ich8lan(9) and honestly? she's a niche icon but she works. let's get into it 🎀

🌸 NAME

e1000e_igp3_phy_powerdown_workaround_ich8lan — the power-down workaround on D3. literally her whole personality is "make the PHY behave when we put it to sleep" 💤

🦋 SYNOPSIS

void e1000e_igp3_phy_powerdown_workaround_ich8lan (struct e1000_hw *hw );

no return value, no drama, just vibes and a pointer 💅

✨ ARGUMENTS

  • hw — pointer to the HW structure 🫶 that's it, that's the whole arg list. she takes one (1) friend to the function.

🔥 DESCRIPTION

so the lore: this is a workaround for 82566 power-down on D3 entry. hardware being hardware, she doesn't just power down nicely on her own, so we do the lil ritual 👑

  1. disable gigabit link — bye bye gigabit, we're not taking you to sleep with us 💀
  2. write VR power-down enable — set the bit, manifest the power-down ✨
  3. read it back — and here's the plot twist: Continue if successful, else issue LCD reset and repeat 😭 if the read-back says "nope", we hit her with an LCD reset and run it back. again and again until she cooperates. it's giving perseverance, it's giving main character energy 🌈

no cap, it's a loop with feelings. and by feelings i mean a reset. 🔁
