💌 send_msg_to_mgmt(9) — a.k.a. the kernel API manual moment

okay bestie, so this whole page is literally about send_msg_to_mgmt(9) from the Kernel API Manual — yes, that's a section 9 manpage, we're in kernel-doc territory, stay with me 🫶

✨ NAME ✨

send_msg_to_mgmt — send message to mgmt by API CMD 💅

🦋 SYNOPSIS 🦋

int send_msg_to_mgmt (struct hinic_pf_to_mgmt *pf_to_mgmt , enum
hinic_mod_type mod , u8 cmd , u8 *data , u16 data_len , enum
msg_ack_type ack_type , enum mgmt_direction_type direction , u16
resp_msg_id );

that's the whole vibe, no cap — int comes back, and everything else is the guest list 🎀

👑 ARGUMENTS 👑

  • pf_to_mgmt — the PF to MGMT channel, aka the actual phone line we're calling on 📞
  • mod — the module in the chip that will get the message, so like, who's receiving the text 💌
  • cmd — command of the message, the point of it all
  • data — the msg data, the payload bestie
  • data_len — the msg data length, because we respect boundaries ✨
  • ack_type — ask for response, i.e. do we want a text back or are we ghosting 👻
  • direction — the direction of the original message, so we know which way it's headed 🧭
  • resp_msg_id — msg id to response for, the little reply-to tag 🏷️

🌸 DESCRIPTION 🌸

short and iconic: return 0 for success, negative for failure. that's it. that's the whole personality 🌈

lowkey important though — if it's negative, something went off, so pls check it fr fr 😭
