__e1000e_read_phy_reg_igp(9)

📦 version 7.3.1, in nixpkgs unstable

💅 __e1000e_read_phy_reg_igp(9) — like, the Kernel API Manual girlies know ✨

okay so bestie, welcome to the Kernel API Manual corner of the internet 🎀 this one is __e1000e_read_phy_reg_igp, and yes the double underscore is part of the name, it's giving "internal function, don't @ me" energy 💅

🌸 NAME 🌸

__e1000e_read_phy_reg_igp — read an igp PHY register 🦋 literally that's the whole vibe, it reads a register, slay

✨ SYNOPSIS ✨

s32 __e1000e_read_phy_reg_igp (struct e1000_hw *hw , u32 offset , u16
*data , bool locked );

look at her go 😭 returns an s32, takes four args, that's it, that's the whole function signature, no cap 🔥

🫶 ARGUMENTS 🫶

  • hw — pointer to the HW structure 💖 like, hand her the hardware struct and she'll know what to do with it
  • offset — register offset to be read 🌸 this is which register we're peeking at
  • data — pointer to the read data ⭐ she writes the stuff she read into here, so it better be a real pointer bestie
  • locked — semaphore has already been acquired or not 🎀 true means you already grabbed the semaphore, false means she's gotta grab it herself

👑 DESCRIPTION 👑

okay so here's the tea ☕ she acquires the semaphore, if necessary, then reads the PHY register at offset and stores the retrieved information in data. 🦋

and the way she's polite about it?? she releases any acquired semaphores before exiting 😭 like a good houseguest, she cleans up after herself, periodt 💅

no cap, that's the entire function. acquire if needed → read → store → release if you acquired. iconic, efficient, main character energy 👑

ngl bestie, the locked flag is doing the heavy lifting here — don't be out here telling her you already have the semaphore when you don't, that's a vibe check she will NOT pass 💀
