iavf_virtchnl_ptp_get_time(9)

🌸 NAME 🌸

okay so welcome to the Kernel API Manual, bestie! 💖 Today’s page is iavf_virtchnl_ptp_get_time — she literally responds to VIRTCHNL_OP_1588_PTP_GET_TIME. That’s it, that’s her whole job, and she ate 💅✨

🦋 SYNOPSIS 🦋

void iavf_virtchnl_ptp_get_time (struct iavf_adapter *adapter , void
       *data , u16 len );

🎀 ARGUMENTS 🎀

• adapter — the private adapter structure, aka her lil internal home base 🏠
• data — the message from the PF, like the text bubble that just landed 📩
• len — length of the message from the PF, aka how many bytes we’re reading 📏

💜 DESCRIPTION 💜

okay so this function handles the VIRTCHNL_OP_1588_PTP_GET_TIME message from the PF. The PF sends this message in response to the same op as a request from the VF. Our job is to extract the 64bit nanoseconds time from the message and store it in cached_phc_time. Then we notify any thread that is waiting for the update via the wait queue. It’s giving synchronization with main character energy, no cap 🔥🕰️
