ipc_trace_init(9)

💖 ipc_trace_init(9) 💖

okay so real talk, bestie — this is a page straight out of the Kernel API Manual (yes, the Kernel API Manual, like the big-league manual, iykyk) and it's about one single lil function that sets the whole stage. it's giving "opening act that actually slays" energy. let's get into it 🎀

---

✨ NAME ✨

ipc_trace_init — literally creates the trace interface and the debugfs entries. that's the whole job. two things, both iconic, no notes 💅

---

🦋 SYNOPSIS 🦋

struct iosm_trace * ipc_trace_init (struct iosm_imem *ipc_imem );

like, you hand it an ipc_imem and it hands you back a struct iosm_trace *. simple as. 🫶

---

🌸 ARGUMENTS 🌸

• ipc_imem — a pointer to the iosm_imem structure. that's it, that's the whole argument. one (1) pointer, and it's to an iosm_imem structure. she's low maintenance, we love that 💖

---

⭐ RETURN ⭐

it returns a pointer to the trace instance on success — slay, ate, no crumbs ✨ — and if it doesn't work out? it returns NULL. that's the else. NULL. the void. the empty group chat. 😭

ngl, always vibe check your return value before you dereference it. NULL is not your friend here, bestie 🙈

---

🔥 SEE ALSO 🔥

• the kernel file ./drivers/net/wwan/iosm/iosm_ipc_trace.c — that's where the magic literally lives, go read it, it's right there 👑
• ipc_trace_port_rx(9) — the rx-side friend, highly recommend
• ipc_trace_deinit(9) — the cleanup queen, the counterpart, the "we're done here" 💀

---

and that's the page!! short, sweet, and honestly kind of a bop 🌈

okay but the actual sign-off: this page lives in ./drivers/net/wwan/iosm, and it's dated October 2026 — so yeah, she's from the future, we don't question it 💜🧚💫
