ice_ptp_pre...cval_ll_e810(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to ice_ptp_prep_phy_incval_ll_e810(9) from the Kernel API Manual 💖 — this is the glow-up version of the page, but every technical deet is still here, fr fr. ✨

🌸 NAME

ice_ptp_prep_phy_incval_ll_e810 — prep PHY ports increment value change 🎀

✨ SYNOPSIS

the signature is literally this, no cap:

int ice_ptp_prep_phy_incval_ll_e810 (struct ice_hw *hw , u64 incval );

🎀 ARGUMENTS

two args, bestie:

  • hw — pointer to HW struct
  • incval — The new 40bit increment value to prepare

🦋 DESCRIPTION

okay so this one uses the low latency firmware interface to program the PHY time increment value for all PHY ports — all of them. it’s giving “one incval to rule all PHY ports” energy, and honestly? iconic. 👑💅

🌈 RETURN

0 on success, -EBUSY on timeout. so if the vibe check times out, you get -EBUSY, bestie 😭

💜 SEE ALSO

the kernel file is literally ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c — that’s the main character. then the see-also friend group is huge and I’m obsessed; every single one is below, no cap:

signing off from the Kernel API Manual 💖 — source/version is ./drivers/net/ethernet/intel/ice, date is October 2026, and the page title is ice_ptp_pre...cval_ll_e810(9). bye bestie, go program those PHY ports 🫶✨
