💅 ice_is_64b_phy_reg_eth56g — a Kernel API Manual moment (section 9, bestie)

okay so real talk: this is the ice_is_64b_phy_reg_eth56g(9) page from the Kernel API Manual, and it's honestly a little icon of a function. it does one job, it does it well, and it tells you the truth about whether the address you're holding is a big girl 64-bit PHY register. periodt. 💖

✨ NAME ✨

ice_is_64b_phy_reg_eth56g — literally just checks if this is a 64bit PHY register. that's it. that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

bool ice_is_64b_phy_reg_eth56g (u16 low_addr , u16 *high_addr );

she takes two things and gives you back a bool, no cap. 🦋

🫶 ARGUMENTS 🫶

  • low_addr — the low address you wanna check. like, the starting point, the main character of this whole operation. 👑
  • high_addr — on return, this holds the high address of the 64bit register. so she writes back into it — pointer energy fr fr. ✨

💅 DESCRIPTION 💅

Write the appropriate high register offset to use.

that's it. that's the description. the original manpage is out here giving minimal-effort queen behavior and honestly? respect. 😭 you call her, she figures out the high register offset, you go use it. iykyk. 💜

🔥 RETURN 🔥

  • true — the low address you handed over is one of the known 64bit PHY values represented as two 32bit registers. slay, it's a match. 🎉
  • false — it is not. no match, no drama, moving on. 🙈

🌈 SEE ALSO 🌈

first up, the actual kernel file this lives in:

  • Kernel file ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c

and then the entire extended friend group — every single one of these, bestie, all of them, no skipping:

okay that's the whole page, and yes i read every single one of those references so you didn't have to. 🧚

sign-off time, bestie: this little masterpiece lives in ./drivers/net/ethernet/intel/ice, it's dated October 2026, and its whole name-and-number is ice_is_64b_phy_reg_eth56g(9). screenshot it, memorize it, tell your friends. mwah. 💖✨🎀
