π ice_get_ptp_src_clock_index(9) π
okay so bestie, welcome to the Kernel API Manual, section 9 β we're literally in the kernel docs rn and this page is about one tiny but iconic function π
β¨ NAME β¨
ice_get_ptp_src_clock_index β figure out which source clock index is in use rn, no cap
πΈ SYNOPSIS πΈ
u8 ice_get_ptp_src_clock_index (struct ice_hw *hw );
π¦ ARGUMENTS π¦
hwβ pointer to the HW struct, that's it, that's the whole argument π«Ά
π DESCRIPTION π
So the whole vibe here: this function determines the source clock index that's currently in use. And how does it know? It goes off the device capabilities that were reported during initialization. That's the tea. ββ¨
Like, no guessing, no vibes-based detection β it's just reading what the device already told us back when it initialized. Main character energy fr. π
π₯ SEE ALSO π₯
first up, the actual kernel file this lives in β go read it, it's giving source of truth:
./drivers/net/ethernet/intel/ice/ice_ptp_hw.c
and then... bestie. the whole ice PTP friend group showed up. every single one of them. here they all are, in order, untouched, exactly as listed ππ
