💅 idpf_ptp_update_tstamp_tracker — Kernel API Manual, section 9 ✨

okay bestie, gather round, because this is a little kernel helper from the Kernel API Manual (section 9, the fun one) and honestly? it's giving very specific, very niche, very iconic 🎀

🌸 NAME 🌸

idpf_ptp_update_tstamp_tracker — updates the Tx timestamp tracker based on the skb compatibility, no cap 💖

✨ SYNOPSIS ✨

bool idpf_ptp_update_tstamp_tracker (struct
       idpf_ptp_vport_tx_tstamp_caps *caps , struct sk_buff *skb , enum
       idpf_ptp_tx_tstamp_state current_state , enum idpf_ptp_tx_tstamp_state
       expected_state );

she returns a bool, she takes four arguments, she's booked and busy 🫶

🦋 ARGUMENTS 🦋

  • caps — the Tx timestamp capabilities; these are the ones monitoring the latch status. think of them as the little clipboard-holder keeping an eye on things 👀
  • skb — the skb whose tstamp value gets returned via virtchnl message. yes, that skb. the main character of this whole operation 💅
  • current_state — the current state of the Tx timestamp latch, aka where we're at right now, fr fr
  • expected_state — the expected state of the Tx timestamp latch, aka where we're supposed to be. the vibe check target 🌈

🔥 DESCRIPTION 🔥

so what she does is: find a proper skb tracker — one that the Tx timestamp is actually received for — and then change the state to the expected value. that's it. that's the whole job. lowkey elegant, highkey essential ⭐

like, she's matching up trackers and flipping states, and honestly? obsessed with her focus 🧚

👑 RETURN 👑

returns true if the tracker has been found and updated — slay, she ate 💖

returns false otherwise — not me crying, it's fine, we move 😭

💀 real talk though: this page is straight from ./drivers/net/ethernet/intel/idpf, dated October 2026, section 9. that's the whole receipt, iykyk 🧾✨

k bye, go update some trackers, ily, don't forget to close your brackets 🫶💅🎀
