💌 ice_aq_send_msg_to_vf — the kernel API manual bestie 💌

okay so this page lives in the Kernel API Manual, section 9, and honestly? it's giving "PF sliding into the VF's DMs" energy. we're talking ice_aq_send_msg_to_vf, no cap 💅

✨ NAME ✨

ice_aq_send_msg_to_vf — (the original NAME section is literally just vibes and the function name, so here's the function name: ice_aq_send_msg_to_vf 🫶)

🌸 SYNOPSIS 🌸

int ice_aq_send_msg_to_vf (struct ice_hw *hw , u16 vfid , u32 v_opcode ,
u32 v_retval , u8 *msg , u16 msglen , struct ice_sq_cd *cd );

like, seven arguments. seven. she's high-maintenance but she delivers ✨

🎀 ARGUMENTS 🎀

  • hw — pointer to the hardware structure. the main character of the whole situation ngl 🌈
  • vfid — VF ID to send msg. it's the @ of the VF you're texting 💌
  • v_opcode — opcodes for VF-PF communication. literally the message type, iykyk
  • v_retval — return error code. yes bestie, you're sending the error code too 💀
  • msg — pointer to the msg buffer. the actual text of the DM 🍓
  • msglen — msg length. don't forget it, that's how long the DM is 🙈
  • cd — pointer to command details. the little metadata receipt, we love her 👑

💖 DESCRIPTION 💖

so what she does: she sends a message to the VF driver — that's opcode 0x0802 btw, write it down 📝 — using the mailbox queue, and she does it asynchronously by sending the message via the ice_sq_send_cmd function. so you fire it off and go live your life, she'll handle it 🔥

ok but fr fr, remember: async. you're not blocking here, so don't come crying when the reply shows up later 💅
