ipc_mux_dl_acb_send_cmds(9)

👑 ipc_mux_dl_acb_send_cmds — a.k.a. the Kernel API Manual page you didn't know you needed

okay so this is from the Kernel API Manual, bestie, and it's about one (1) very specific little function. let's get into it 💅

---

🌸 NAME 🌸

ipc_mux_dl_acb_send_cmds — literally just Respond to the Command blocks. that's the whole vibe. it responds. to command blocks. periodt ✨

---

🦋 SYNOPSIS 🦋

int ipc_mux_dl_acb_send_cmds (struct iosm_mux *ipc_mux , u32 cmd_type ,
u8 if_id , u32 transaction_id , union mux_cmd_param *param , size_t
res_size , bool blocking , bool respond );

^^ that's the whole signature, copied character for character because we do not play with technical details in this house 🫶

🎀 ARGUMENTS 🎀

• ipc_mux — a pointer to the MUX data-struct. yes bestie, MUX. with a capital M. iconic.
• cmd_type — the Command. like, the actual command. the what.
• if_id — the Session interface id. iykyk.
• transaction_id — the Command transaction id, so everybody knows which transaction is which 🔥
• param — pointer to the command params. the little extras. the seasoning 🍓
• res_size — the Response size. how much response are we talking.
• blocking — True for blocking send. so if it's true, it waits, no cap 😭
• respond — if true, return transaction ID. simple as that. no notes 👑

---

⭐ RETURN ⭐

0 in success, and a failure value on error. so like, if you get 0, slay 💖. if you don't, something's up and you should probably care about that.

🌈 SEE ALSO 🌈

okay this is the part where I list literally everything, because every single one of these matters, and I refuse to leave a single one out:

• Kernel file ./drivers/net/wwan/iosm/iosm_ipc_mux_codec.h
• struct mux_cmdh(9)
• struct mux_acbh(9)
• struct mux_adbh(9)
• struct mux_adth(9)
• struct mux_adgh(9)
• struct mux_lite_cmdh(9)
• struct mux_lite_vfl(9)
• struct ipc_mem_lite_gen_tbl(9)
• union mux_type_cmdh(9)
• union mux_type_header(9)
• ipc_mux_netif_tx_flowctrl(9)
• ipc_mux_ul_trigger_encode(9)
• ipc_mux_ul_data_encode(9)
• ipc_mux_ul_encoded_process(9)

that's fifteen entries and I counted twice. main character energy across the board 👑✨

💀 real talk though: if you're deep in ./drivers/net/wwan/iosm territory, you're built different. good luck and godspeed, bestie.

and that's the page!! 🧚 sign-off time: this one comes from ./drivers/net/wwan/iosm, dated October 2026, and it's the manual page for ipc_mux_dl_acb_send_cmds(9). go forth and respond to those command blocks, icon 💜🌸
