recv_mgmt_msg_handler(9)

💖 recv_mgmt_msg_handler — bestie edition 💖

okay so this is the manpage for recv_mgmt_msg_handler(9), a kernel API function and honestly? it's giving "small but crucial." no cap. it's the handler for a message from the mgmt cpu, and if that sounds niche, that's because it is, but that's also why we love it. 🫶

✨ SYNOPSIS ✨

void recv_mgmt_msg_handler (struct hinic_pf_to_mgmt *pf_to_mgmt , u64
*header , struct hinic_recv_msg *recv_msg );

literally the whole function signature, copied exactly, periodt. 💅

🎀 ARGUMENTS 🎀

• pf_to_mgmt — the PF to MGMT channel. this is the connection, the link, the situationship between PF and MGMT, if you will. 😭
• header — the header of the message. not the message itself, bestie, just the header. the little name tag before the actual content walks in. 💌
• recv_msg — received message details. all the juicy specifics of what came in. this is the "Important Part™" of the args. 🍓

🌈 SEE ALSO 🌈

okay so there's a whole squad of mgmt message functions and honestly they're all iconic. here's the full lineup, and no, I'm not skipping a single one, that would be disrespectful. 💀

• Kernel file ./drivers/net/ethernet/huawei/hinic/hinic_hw_mgmt.c
• hinic_register_mgmt_msg_cb(9) — the sign-up sheet for callbacks, we love a registration moment 👑
• hinic_unregister_mgmt_msg_cb(9) — the un-registration, the goodbye, the "it's not you it's the mgmt channel" 😭
• prepare_header(9) — prepping the header, main character energy 💅
• prepare_mgmt_cmd(9) — prepping the command, also main character energy 🎀
• mgmt_msg_len(9) — the length check, because size matters (it's a nerd joke, I had to) 🤓
• send_msg_to_mgmt(9) — sending it! to management!! ✨
• msg_to_mgmt_sync(9) — the synchronous version, it waits for you to finish talking 🫶
• msg_to_mgmt_async(9) — the asynchronous version, it does NOT wait, it's busy, it has plans 🌸
• hinic_msg_to_mgmt(9) — the general hinic version of talking to mgmt 🦋
• mgmt_recv_msg_handler(9) — the receive handler, this function's cousin 💜
• mgmt_resp_msg_handler(9) — the response handler, the reply guy 😭
• mgmt_msg_aeqe_handler(9) — the AEQE handler, keeping it real with event queues 🔥
• alloc_recv_msg(9) — allocation time, we allocate the receive message 🧚
• alloc_msg_buf(9) — allocation time again, but for the buffer this time 🎀
• hinic_pf_to_mgmt_init(9) — the init, the beginning, the origin story ⭐
• hinic_pf_to_mgmt_free(9) — the free, the cleanup, the "we're done here" 💀

also like. genuinely go read ./drivers/net/ethernet/huawei/hinic/hinic_hw_mgmt.c if you want the actual receipts, that's the kernel file where the magic lives. 📁

💜 a cute little sign-off 💜
