ipc_port_init(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… ipc_port_init(9) β€” the kernel API manual, but make it make sense

okay so bestie, welcome to ipc_port_init(9) β€” yes that's the man page name AND the function name, we're keeping it iconic like that. This one lives in the Kernel API Manual, and it's basically the moment a fresh IPC port gets born and introduced to the wwan subsystem so AT/MBIM communication can actually happen. πŸŽ€


✨ NAME ✨

ipc_port_init β€” allocate an IPC port & register it to the wwan subsystem for AT/MBIM communication. that's the whole job. allocate, register, slay. πŸ’…


🌸 SYNOPSIS 🌸

struct iosm_cdev * ipc_port_init (struct iosm_imem *ipc_imem , struct
ipc_chnl_cfg ipc_port_cfg );

so it takes two args and hands you back a struct iosm_cdev *. keep that exact signature, bestie, don't be out here freestyling types. ✨


πŸ¦‹ ARGUMENTS πŸ¦‹

  • ipc_imem β€” Pointer to iosm_imem structure. just a pointer, that's it, that's the whole vibe.
  • ipc_port_cfg β€” IPC Port Config. the config for the port, iykyk.

🫢 RETURN 🫢

0 on success & NULL on failure.

ngl the page literally says 0 on success and NULL on failure β€” that's what it says, so that's what we're telling you. don't @ me, @ the doc. 😭

🧚 SEE ALSO 🧚

  • Kernel file ./drivers/net/wwan/iosm/iosm_ipc_port.h and struct iosm_cdev(9) β€” go read the header, it's giving lore.
  • ipc_port_deinit(9) β€” the breakup arc. when the port's done, this is who you call. πŸ’€

lowkey important: if you're messing with this, keep ipc_port_init(9) and ipc_port_deinit(9) in the same mental folder. one brings it into the world, one takes it out. main character energy on both sides. πŸ‘‘

that's the whole page, no cap β€” every flag, arg, and reference accounted for. now go forth and register those ports. 🌈

πŸ’– sign-off time: this lil gem comes from the kernel source tree at ./drivers/net/wwan/iosm, dated October 2026, and it's page ipc_port_init(9). mwah, bye bestie 🫢✨
