📦 version 7.3.1, in nixpkgs unstable

💖 igc_ptp_systim_to_hwtstamp(9) — the kernel API manual, but make it cute 🎀

okay so bestie, welcome to the igc_ptp_systim_to_hwtstamp page from the Kernel API Manual ✨ this one's a little function with a big job and honestly? it ate. let's get into it 💅

✨ NAME ✨

igc_ptp_systim_to_hwtstamp — literally converts a system time value into a HW timestamp 🕰️✨

🌸 SYNOPSIS 🌸

int igc_ptp_systim_to_hwtstamp (struct igc_adapter *adapter , struct
       skb_shared_hwtstamps *hwtstamps , u64 systim );

that's it, that's the whole vibe. three args, one int return, no cap 🫶

🦋 ARGUMENTS 🦋

  • adapter — the board private structure 👑 like, the whole adapter's personal business
  • hwtstamps — the timestamp structure you're updating 💖 she gets written to, she's the main character
  • systim — an unsigned 64bit system time value 🔥 sixty-four whole bits of it

💀 DESCRIPTION 💀

so here's the situation bestie: we have a system time value chillin' in the RX/TXSTMP registers, and it's giving raw. we need to convert that value into a hwtstamp — one that the upper level timestamping functions can actually use 😭🙈

it's a glow-up. register value in, usable hwtstamp out. iconic behavior honestly.

returns 0 on success ✅ that's the good ending, we love a zero return
