📦 version 7.3.1, in nixpkgs unstable

💅 i40e_ptp_get_rx_events 💅

okay so bestie, welcome to the Kernel API Manual ✨ — yes, that's the manual name, we're fancy here — and today's main character is i40e_ptp_get_rx_events(9). buckle up, this one's short but she matters 🎀

✨ NAME ✨

i40e_ptp_get_rx_events — read I40E_PRTTSYN_STAT_1 and latch events 💅 no cap, that's literally the whole job description

🌸 SYNOPSIS 🌸

u32 i40e_ptp_get_rx_events (struct i40e_pf *pf );

that's it. that's the whole vibe. one arg, one u32 coming back at you 🦋

🎀 ARGUMENTS 🎀

  • pf — the PF data structure 💖 (the driver's whole personality lives in there, so like, handle with care)

💖 DESCRIPTION 💖

so what she actually does: this function reads I40E_PRTTSYN_STAT_1 and updates the corresponding timers for any latch events she noticed 👀✨

and why do we care? because this lets the driver keep track of the first time a latch event was noticed — that timestamp is then used to help clear out Rx timestamps for packets that got dropped or lost 😭🫶 lowkey a cleanup queen

she also returns the current value of I40E_PRTTSYN_STAT_1 — that's the u32, that's the tea ☕

⚠️ important, bestie: this function is expected to be called only while under the ptp_rx_lock 🔒 like, no sneaking in without the lock, that's not the move. periodt.
