okay so bestie, welcome to the Kernel API Manual β¨ this one's a lil kernel-function page and it is, lowkey, very niche and very iconic of it. buckle up π
β¨ NAME β¨
ice_ptp_prep_phy_incval_e810 β literally just "Prep PHY port increment value change" π« that's the whole job. that's the assignment. she's a preparer, not a finisher, and we respect that π«Ά
πΈ SYNOPSIS πΈ
int ice_ptp_prep_phy_incval_e810 (struct ice_hw *hw , u64 incval );
yes the spacing is exactly like that, do not @ me, that's how it's written π
π¦ ARGUMENTS π¦
hwβ pointer to HW struct π§ your hardware-facts-in-a-struct situation.incvalβ The new 40bit increment value to prepare β forty. bits. not thirty-two, not sixty-four, forty β¨
π DESCRIPTION π
So the whole vibe here is: you're getting the PHY port ready for a brand new increment value. Not doing it β prepping for it. main character energy is doing the setup and letting someone else take the bow π
The prepping happens by programming the PHY ETH_GLTSYN_SHADJ_L and ETH_GLTSYN_SHADJ_H registers π those two, in that order, them's the ones.
lowkey important bestie: this function does not finish the job. the actual change is completed by issuing an ICE_PTP_INIT_INCVAL command π so if you're sitting there wondering why nothing happened yetβ¦ yeah. you gotta issue the command. the prep alone is giving "set the table but nobody's eating" π
π SEE ALSO π
the source lives in the kernel file ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c β go say hi π
and now, the friend group. it's a big friend group. i'm listing literally every single one because i'm not about to leave a bestie out π
