💖 qed_chain_alloc(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, we're being official today 💅 — and today's main character is qed_chain_alloc. Buckle up.

---

✨ NAME ✨

qed_chain_alloc — literally allocates and initializes a chain. that's the whole vibe. allocate + init, one function, iconic behavior 🎀

---

🦋 SYNOPSIS 🦋

int qed_chain_alloc (struct qed_dev *cdev , struct qed_chain *chain ,
struct qed_chain_init_params *params );

like yes, it returns an int. yes, there are three arguments. yes, you're gonna read all of them below, no skipping 🙈

---

🌸 ARGUMENTS 🌸

• cdev — the main device structure. the big boss. the main character energy of the whole thing 👑
• chain — the chain to be processed. this is the one getting the glow-up 💖
• params — the chain initialization parameters. all the settings, all the details, all the how-to 🫶

---

⭐ RETURN ⭐

0 on success 🎉 — and a negative errno otherwise 😭. so like, check your return value, bestie, fr fr.

ngl if you get a negative errno back, the chain did not slay. handle it.
