💅 igb_write_phy_reg_igp(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the igb_write_phy_reg_igp page from the Kernel API Manual 🎀 this one's short and sweet and honestly kind of iconic for it.

🌸 NAME 🌸

igb_write_phy_reg_igp — write an igp PHY register 💖

✨ SYNOPSIS ✨

s32 igb_write_phy_reg_igp (struct e1000_hw *hw , u32 offset , u16 data
);

like, that's the whole signature. no notes. she's tidy 🫶

🦋 ARGUMENTS 🦋

  • hw — pointer to the HW structure 💅 that's your hardware context right there, the main character of this whole operation
  • offset — register offset to write to ⭐ literally which register you're sliding into
  • data — data to write at register offset 🌸 the actual payload, the moment, the reason we're all here

🌈 DESCRIPTION 🌈

okay so here's the vibe: she acquires the semaphore first — but only if necessary, no cap 🙈 — and then she writes the data to the PHY register at the offset. super straightforward, does exactly what it says on the tin 💜

and then, bestie, listen: she releases any acquired semaphores before exiting 👑 not me being obsessed with proper cleanup. she does NOT leave a semaphore held on her way out. that's called manners and she has them fr fr ✨
