mpi3mr_alloc_trace_buffer(9)

💖 mpi3mr_alloc_trace_buffer(9) — Kernel API Manual 💖

okay bestie, welcome to the mpi3mr_alloc_trace_buffer(9) page. It's giving kernel API realness, but we're gonna make it make sense. 🫶

---

✨ NAME ✨

mpi3mr_alloc_trace_buffer — Allocate segmented trace buffer 🌸

---

🦋 SYNOPSIS 🦋

int mpi3mr_alloc_trace_buffer (struct mpi3mr_ioc *mrioc , u32 trace_size
);

---

🎀 ARGUMENTS 🎀

• mrioc — Adapter instance reference. That's the adapter instance reference, periodt. 💅
• trace_size — Trace buffer size. Exactly the trace buffer size, no cap. ✨

---

🌈 DESCRIPTION 🌈

Okay so this function allocates the host trace buffer. Depending on the controller capability, it allocates either segmented memory pools or a contiguous buffer. That's the whole plot, bestie. 🦋

---

⭐ RETURN ⭐

Returns 0 on success, non-zero on failure. So 0 is the slay result, and anything non-zero is a nope. 💀
