π ice_ptp_src_cmd β Kernel API Manual β¨
okay so bestie, welcome to the glow-up of ice_ptp_src_cmd, straight out of the Kernel API Manual. this one's short and sweet but she's important, so pay attention π
β¨ NAME β¨
ice_ptp_src_cmd β get the source timer all dressed and ready for a timer command π«Ά
πΈ SYNOPSIS πΈ
void ice_ptp_src_cmd (struct ice_hw *hw , enum ice_ptp_tmr_cmd cmd );
like, that's the whole vibe. no return value, she just does the thing π
π¦ ARGUMENTS π¦
hwβ a pointer to the HW structure. yes queen, the hardware struct, she holds everything ποΈcmdβ the Timer command. the actual instruction you're handing over β°
π DESCRIPTION π
Prepare the source timer for an upcoming timer sync command. that's it, that's the whole flex. she sets things up so the source timer is ready to go when the sync command lands, and then she dips β¨
ngl she doesn't do the syncing herself β she's the prep girl, the getting-ready-with-you-in-the-bathroom friend, and the actual sync is somebody else's main character moment π
π SEE ALSO π
go read the actual source, it lives here π
Kernel file ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c
