📦 version 7.3.1, in nixpkgs unstable

💅 e1000_write_flash_byte_ich8lan(9) — from the Kernel API Manual

okay so bestie, welcome to the Kernel API Manual entry for e1000_write_flash_byte_ich8lan(9). yes the header is long, yes it got truncated to e1000_write_...byte_ich8lan(9) up top, that's just how the man page wears its name. we move 💖

✨ NAME ✨

e1000_write_flash_byte_ich8lan — write a single byte to NVM. one byte. that's the whole assignment. iconic minimalism 🎀

🌸 SYNOPSIS 🌸

s32 e1000_write_flash_byte_ich8lan (struct e1000_hw *hw , u32 offset ,
u8 data );

literally the whole signature, no cap. it hands you back an s32 🫶

🦋 ARGUMENTS 🦋

  • hw — pointer to the HW structure. the main character of this whole file, fr fr 👑
  • offset — The index of the byte to read. (yes, it says read, that's what the manual says, don't come for me 😭 — this is the offset you're handing over)
  • data — The byte to write to the NVM. this is the actual payload, the lil guy going into storage 🍓

🔥 DESCRIPTION 🔥

Writes a single byte to the NVM using the flash access registers. that's it, that's the vibe check — one byte in, via the flash access registers, and you're done ✨

not me being obsessed with how simple this is. highkey a one-job function and it does its job 💅

🌈 SEE ALSO 🌈

the bestie list is long, so buckle up — every single sibling function is down here, plus the source file itself. no gatekeeping 🫶

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

and the whole friend group:

go read all ninety-four of them. i'll wait 💜

ngl the source line at the bottom is cut off at ./drivers/net/ethernet/intel/e... — that's the source/version stamp, dated October 2026, and the page footer repeats e1000_write_...byte_ich8lan(9) right back at you. so yeah, ./drivers/net/ethernet/intel/e... + October 2026 + that gloriously abbreviated title — mwah, that's the sign-off bestie, slay your day 💖🎀🦋
