ice_ptp_release(9)

💖 NAME 💖

welcome to the Kernel API Manual, section 9 — today's main character is ice_ptp_release, and she is here to disable the driver/HW support and unregister the clock. periodt. 💅

✨ SYNOPSIS ✨

void ice_ptp_release (struct ice_pf *pf );

🎀 ARGUMENTS 🎀

• pf — board private structure. that's the whole description and honestly she's serving mystery. no cap. 😌

🌸 DESCRIPTION 🌸

okay so bestie, ice_ptp_release() handles the cleanup work required from the initialization. the way it does that is by clearing out the important information and unregistering the clock. it's giving "pack up your stuff, unregister the clock, and go" energy. the return type is void, so nothing comes back — she just does the cleanup and exits. 🫶✨

🦋 SEE ALSO 🦋

first, the kernel file itself is at ./drivers/net/ethernet/intel/ice/ice_ptp.c — go read it, it's iconic. 🔥

okay bestie, that's the page. this one comes from the ./drivers/net/ethernet/intel/ice source — that's the source/version situation — and it's dated October 2026. mwah, now go read the source and slay 💋🌈
