💅 igb_read_phy_reg_igp(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for igb_read_phy_reg_igp(9), and honestly it's giving "quiet little helper function that does one thing and does it well." main character energy, but make it subtle 🎀

🌸 NAME 🌸

igb_read_phy_reg_igp — read igp PHY register 🫶 that's it, that's the whole vibe.

✨ SYNOPSIS ✨

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

like, look at her. three params, one return, no drama 💅

🦋 ARGUMENTS 🦋

  • hw — pointer to the HW structure. it's the hardware bestie, the whole context, the main character of the story 🏠
  • offset — register offset to be read. literally which register we're peeking at 👀
  • data — pointer to the read data. this is where the tea gets stored, and yes it's a pointer to a u16 so the function can write back into it 💖

🌈 DESCRIPTION 🌈

so here's the whole plot: it acquires the semaphore, if necessary, and then reads the PHY register at offset, storing the retrieved information in data. 🍓

and then — the part I need you to not skip, bestie — it releases any acquired semaphores before exiting. like, it cleans up after itself. we love a function with manners 😭👑

fr fr though, the "if necessary" and the "any acquired" are doing real work there — the semaphore part is conditional, and the cleanup matches whatever it grabbed. no cap. 🧚

👑 SEE ALSO 👑

the kernel file lives at ./drivers/net/ethernet/intel/igb/e1000_phy.c 📁 — that's the home base, iykyk.

and now the whole friend group, because this function does NOT exist in a vacuum, she's got a whole extended family 💀:

like, forty-plus siblings. iconic. ate. periodt. 🔥

and that's the whole page, bestie 🫶 this one's stamped from ./drivers/net/ethernet/intel/igb and dated October 2026 — so like, future-coded but make it source tree. mwah 💋✨
