e1000e_read_phy_reg_bm(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… e1000e_read_phy_reg_bm β€” from the Kernel API Manual, bestie edition ✨

okay so you opened the Kernel API Manual page for e1000e_read_phy_reg_bm and it's giving "dry technical document" energy, but don't worry, I'm gonna translate it for you 🫢


✨ NAME ✨

e1000e_read_phy_reg_bm β€” literally just "Read BM PHY register" πŸŽ€ that's the whole vibe, no cap.


🌸 SYNOPSIS 🌸

s32 e1000e_read_phy_reg_bm (struct e1000_hw *hw , u32 offset , u16 *data
);

look at that signature. she's iconic. she returns an s32, she takes your hw, your offset, your data pointer, and she gets stuff done πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • hw β€” pointer to the HW structure ✨ your hardware's little passport, basically. everything starts here.
  • offset β€” register offset to be read πŸ“ the exact spot in PHY-land you're trying to peek at.
  • data β€” pointer to the read data πŸ“ this is where the good stuff lands. it's a pointer, so like... it's writing through it, iykyk.

πŸ’– DESCRIPTION πŸ’–

so here's the tea: this function acquires the semaphore, if necessary, then reads the PHY register at offset and stores the retrieved information in data. πŸ”₯

and then β€” and this is the respectful part β€” it releases any acquired semaphores before exiting. periodt. no lock left behind, no drama, main character energy but make it polite πŸ’œ

fr fr though, if you were worried about leaked semaphores: she cleans up before she leaves. that's the whole point. 🧚

first up, the source file, because we love a primary source:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/phy.c πŸ“

and now... the friend group. the whole squad. every single one. I'm not skipping a single bestie, that would be disrespectful πŸ™ˆ

like, that's the whole roster. imagine being in that group chat. πŸ’€ anyway, all of them are family, go read their pages too 🌈


and that's the page!! πŸŽ€ source/version situation is ./drivers/net/ethernet/intel/e... and the date on the tin says October 2026, so yeah β€” bookmark it, cite it, love it. slay πŸ’…βœ¨
