dpaa2_io_create(9)

✨ dpaa2_io_create(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this little page is all about dpaa2_io_create — the function that literally births a dpaa2_io object. no cap.

---

🎀 NAME 🎀

dpaa2_io_create — create a dpaa2_io object. that's it. that's the whole vibe. ✨

---

🌸 SYNOPSIS 🌸

struct dpaa2_io * dpaa2_io_create (const struct dpaa2_io_desc *desc ,
struct device *dev );

like… she takes two things and gives you back a pointer. iconic behaviour honestly 🫶

---

🦋 ARGUMENTS 🦋

• desc — the dpaa2_io descriptor. this is the ~blueprint~ bestie, the config energy 💖
• dev — the actual DPIO device. the real one. the main character 👑

---

⭐ DESCRIPTION ⭐

So what does she do? She activates a struct dpaa2_io corresponding to the given config of an actual DPIO object. like, she takes your descriptor config and your real DPIO device and boom — you got yourself a live dpaa2_io. slay 💅

And the returns? very simple, very demure:

• a valid dpaa2_io object → success, we ate 🔥
• NULL → failure, it's giving flop 😭

that's literally the whole deal. no hidden lore.
