📦 version 7.3.1, in nixpkgs unstable

💅 e1000_resum...ounds_pchlan — the Kernel API Manual page, but make it make sense

okay so before we even get into it — this page lives in the Kernel API Manual, bestie. That's the manual name. Say hi 👋

✨ NAME ✨

e1000_resume_workarounds_pchlan — the workarounds you need during Sx->S0 🌀 (yes, waking up is hard for everyone, even NICs)

🫶 SYNOPSIS 🫶

void e1000_resume_workarounds_pchlan (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. that's the whole vibe, she's just a pointer to the hardware struct, no cap 💅

🌸 DESCRIPTION 🌸

okay so picture this: you're going from Sx to S0. During those transitions — on non-managed devices, or on managed devices where PHY resets are not blocked — sometimes the PHY registers just... won't be accessed properly by the s/w 😭 and when that happens, the move is to toggle the LANPHYPC value to power cycle the PHY. literally pulling the plug and replugging on a tiny scale. iconic honestly.

and if you're on i217? you also set up Intel Rapid Start Technology. that's it, that's the job 🫶

ok real talk, this is a workaround function. she is doing workaround things. treat the hardware gently, the PHY resets and power cycles here are load-bearing ✨

🦋 SEE ALSO 🦋

the whole group chat, fr fr — every single one of these is worth a look 👑

also like, the actual kernel file this lives in, in case you wanna read the source like the main character you are:

./drivers/net/ethernet/intel/e1000e/ich8lan.c

and that's the page 🎀 mwah 💋

source + version + date energy: this one's served up from ./drivers/net/ethernet/intel/e..., dated October 2026, and the footer reads e1000_resum...ounds_pchlan(9) — yeah they truncated the title twice, we love a consistent aesthetic ✨ go touch some registers bestie 🦋
