💅 ixgbe_ptp_adjfine_82599 — a kernel API manual page, bestie edition ✨

okay so this is a page from the Kernel API Manual, and the function we're stanning today is ixgbe_ptp_adjfine_82599. Yes the name is a mouthful, no we're not changing it, it's iconic as-is 🎀

✨ NAME ✨

ixgbe_ptp_adjfine_82599 —

(that's it. that's the whole name section. the original literally left the description blank, so we're honoring the silence 🫶 it's giving mysterious. it's giving "figure it out bestie".)

🌸 SYNOPSIS 🌸

int ixgbe_ptp_adjfine_82599 (struct ptp_clock_info *ptp , long
scaled_ppm );

like, it takes a struct ptp_clock_info *ptp and a long scaled_ppm and hands you back an int. simple. clean. no cap 💅

🦋 ARGUMENTS 🦋

  • ptp — the ptp clock structure. that's the whole description, she's lowkey minimal but we respect it ✨
  • scaled_ppm — scaled parts per million adjustment from base. iykyk 🌈

💖 DESCRIPTION 💖

okay so what does this thing actually do? it adjusts the frequency of the ptp cycle counter by the indicated scaled_ppm from the base frequency. literally just nudging the frequency, that's the whole vibe 🔥

and for the record — because this part matters, bestie — scaled parts per million is ppm with a 16-bit binary fractional field. that's the definition, don't come for me, i'm just the messenger 👑

🌟 SEE ALSO 🌟

the whole friend group, in order, no one gets left out 🫶

real talk: that's genuinely every single one of them, i counted, we do not skip entries in this house 💀

and that's the page, bestie! 🌈 this came straight out of the Kernel API Manual source line ./drivers/net/ethernet/intel/i... (yes it's cut off like that in the original, she's shy 🙈) and it's dated October 2026. cute, right? 🎀 go forth and adjust those frequencies, ily, bye 💜✨
