📦 version 7.3.1, in nixpkgs unstable

💅 ice_ptp_cfg_phy_interrupt(9) — like, the PHY interrupt glow-up page

Hey bestie, welcome to the Kernel API Manual section 9 entry for ice_ptp_cfg_phy_interrupt. Yes it's a nine, yes it's kernel-internal, and yes I'm gonna make it make sense. 🫶

✨ NAME ✨

ice_ptp_cfg_phy_interrupt — the function that handles Configure PHY interrupt settings. That's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

int ice_ptp_cfg_phy_interrupt (struct ice_pf *pf , bool ena , u32
threshold );

Like — it returns an int, sits on a struct ice_pf *pf, and takes a bool plus a u32. Iconic signature, no notes. 💅

🦋 ARGUMENTS 🦋

  • pf — the PF private structure. Your whole personality lives in here. 👑
  • ena — a bool value that enables or disables the interrupt. On or off, babe. That's it. ✨
  • threshold — the minimum number of packets at which the interrupt gets triggered. So it's giving "don't @ me until you've got enough packets". 🌈

💖 DESCRIPTION 💖

Okay so this is a utility function, right? Its whole job is to configure all the PHY interrupt settings — like, every single one — and that includes two big things:

  • whether the PHY interrupt is enabled (ena, bestie 🌸)
  • what threshold to use (threshold, obviously 💅)

And there's a bonus move: it also configures The E82X timestamp owner to react to interrupts from all PHYs. Note the capital T in "The" — that's how you know it's important, no cap. 👑

⭐ RETURN ⭐

  • 0 — on success. Slay. We love a zero. 🎉
  • -EOPNOTSUPP — when the PHY model is incorrect. 🙈 Wrong PHY, wrong party.
  • other error codes — when it failed to configure the PHY interrupt for E82X. 😭

🔥 SEE ALSO 🔥

So there are, like, a LOT of siblings. Family reunion time, iykyk. Also go read the kernel file ./drivers/net/ethernet/intel/ice/ice_ptp.c — that's the source of truth, bestie. 🧚

Bestie heads-up: that -EOPNOTSUPP is not a vibe, it means the PHY model is straight-up incorrect, so don't go blaming yourself. 💀

Okay that's the whole page, mwah. 😘 This came to you from the kernel source tree at ./drivers/net/ethernet/intel/ice, dated October 2026, in the Kernel API Manual, page ice_ptp_cfg_phy_interrupt(9) — go forth and configure those PHY interrupts, you absolute main character. 🦋💜 🌈
