iavf_aq_send_msg_to_pf(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual page for iavf_aq_send_msg_to_pf — yes, that whole mouthful. It’s giving “kernel function with a long name,” and we’re gonna get through it together. ✨

🌸 SYNOPSIS 🌸

Here’s the exact function signature, no cap:

enum iavf_status iavf_aq_send_msg_to_pf (struct iavf_hw *hw , enum
virtchnl_ops v_opcode , enum iavf_status v_retval , u8 *msg , u16 msglen
, struct iavf_asq_cmd_details *cmd_details );

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure. The hardware bestie in question. 🫶
• v_opcode — opcodes for VF-PF communication. Yep, the opcode vibe check for this message. 💅
• v_retval — return error code. The little error-code corner. 😭
• msg — pointer to the msg buffer. The actual message buffer lives here. 💌
• msglen — msg length. Literally how long the message is. 📏
• cmd_details — pointer to command details. Extra command-details pointer, slay. ✨

🦋 DESCRIPTION 🦋

Okay so here’s the tea: this function sends a message to the PF driver using the admin queue. That’s the whole main-character job. 👑

By default, this message is sent asynchronously, i.e. iavf_asq_send_command does not wait for completion before returning. So it’s not sitting around waiting for the completion glow-up — it returns and keeps it moving. Periodt. 💅
