e1000_write_reg_io(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

e1000_write_reg_io(9) — okay bestie, this is the e1000_write_reg_io(9) page from the Kernel API Manual. The source NAME line is literally e1000_write_reg_io - with nothing after the dash. Minimalist queen behavior, no cap. We are not inventing a description that isn't there.

✨ SYNOPSIS

void e1000_write_reg_io (struct e1000_hw *hw , u32 offset , u32 value );

🎀 ARGUMENTS

  • hw — the struct containing variables accessed by shared code.
  • offset — the offset to write to.
  • value — the value to write.

🦋 DESCRIPTION

Writes a value to one of the device's registers using port I/O (as opposed to memory mapped I/O). Port I/O is the whole vibe here, bestie.

⚠️ Compatibility check, periodt: only 82544 and newer devices support port I/O. So yeah, that's the hardware cutoff.

Cute sign-off time: source/version stamp is ./drivers/net/ethernet/intel/e..., dated October 2026, and this is the e1000_write_reg_io(9) manual page. Bye bestie, go write that register 💅🫶
