e1000_write_smbus_addr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 e1000_write_smbus_addr — a page from the Kernel API Manual

okok so this is a whole manual page, bestie, and it's about exactly one tiny little function that does exactly one tiny little thing. it's giving "small but crucial," and honestly? we love that for it.

🌸 NAME

e1000_write_smbus_addr — write the SMBus address to the PHY, which is a thing you gotta do for Sx states. that's it, that's the job 🫶

✨ SYNOPSIS

s32 e1000_write_smbus_addr (struct e1000_hw *hw );

okay so it takes one thing and hands you back an s32, no cap ✨

🎀 ARGUMENTS

  • hw — pointer to the HW structure. that's your whole hardware world right there, bestie, you're passing the entire struct over and trusting it 🙈

🦋 DESCRIPTION

so the whole vibe of this function is that it assumes the semaphore has already been acquired — like, it is not gonna go grab the lock for you, it fully expects you to have handled that already. please do not show up un-sempahored 💀

also, per the NAME section, this is the "write SMBus address to PHY" move that's needed during Sx states. iconic behavior for a sleepy little network card 🌈

💖 SEE ALSO

the file it lives in, first of all:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/ich8lan.c

and then... the extended family 😭 like genuinely this is a huge family and everybody's getting a mention, so here's the full guest list, in order, exactly as it appears, no cuties left behind:

like I said. a whole family reunion 😭 every single one of them got an invite and yes I alphabetized nothing, this is the original order, we respect the order 🫶

lowkey reminder: this page only documents what's written up there — nothing more, nothing invented. if it's not on this page, I'm not making it up for you, bestie 💀

and that's the whole page! this came from ./drivers/net/ethernet/intel/e... and it's dated October 2026 — so like, future vibes, very main character energy 👑. go off and write that SMBus address, but only after you've handled the semaphore. periodt. 💖✨🎀
