💅 ice_ptp_write_direct_phc_time_e830(9) — Kernel API Manual 💅

okay so bestie, this one's from the Kernel API Manual and it's all about setting up the PHY port clock time before the driver actually commits it. buckle up 🎀

🌸 NAME 🌸

ice_ptp_write_direct_phc_time_e830 — prepare the PHY port with its initial time, that's the whole vibe ✨

🦋 SYNOPSIS 🦋

void ice_ptp_write_direct_phc_time_e830 (const struct ice_hw *hw , u64 time );

no return value, it's a void function, she just does the thing and leaves 💅

🍓 ARGUMENTS 🍓

  • hw — the board private structure, aka the main character struct 🫶
  • time — the time you want to initialize the PHY port clock to ⏰

💜 DESCRIPTION 💜

So here's the tea: this function programs the PHY port ETH_GLTSYN_SHTIME registers, and it's doing that in preparation for setting the initial clock time — like setting the table before the guests arrive, yknow? 🎀

lowkey the biggest thing to know: the time will not actually be programmed until the driver issues an ICE_PTP_INIT_TIME command. so this is the setup, not the finale. periodt. 🫶

And about that time value — it's the upper 32 bits of the PHY timer, usually in units of nominal nanoseconds. iykyk, that upper-half detail matters 💅✨

🔥 SEE ALSO 🔥

okay this is where it gets iconic — the whole ice PTP extended family shows up. the kernel file itself lives at ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c, and then, in order, no cap, every single one:

like… that's the entire friend group, no one got left out 🫶✨

that's the whole page bestie — go set some timestamps responsibly 💅

later, legend 🦋 — this one's straight out of ./drivers/net/ethernet/intel/ice, dated October 2026, filed under ice_ptp_writ...hc_time_e830(9). mwah 💖
