crypto_engin...init_and_set(9)

💅 crypto_engine_alloc_init_and_set(9) — the Kernel API Manual glow-up ✨

okay so bestie, this one's from the Kernel API Manual and it's literally the moment your crypto hardware engine gets its whole life together. the function is crypto_engine_alloc_init_and_set — she's a long name but she ate 🎀

---

✨ NAME ✨

crypto_engine_alloc_init_and_set — allocate crypto hardware engine structure and initialize it by setting the maximum number of entries in the software crypto-engine queue.

like, she's the full package: she allocates the struct and sets the queue length. icon behavior, no cap 👑

---

🦋 SYNOPSIS 🦋

struct crypto_engine * crypto_engine_alloc_init_and_set (struct device
*dev , bool retry_support , bool rt , int qlen );

---

🌸 ARGUMENTS 🌸

• dev — the device attached with one hardware engine. one engine per device, we're monogamous here 💖
• retry_support — whether hardware has support for retry mechanism. it's a bool, so literally yes/no, so real, so simple
• rt — whether this queue is set to run as a realtime task. main character energy only, no being late 🏃‍♀️💨
• qlen — maximum size of the crypto-engine queue. an int, so pick your number wisely bestie 🍓

---

💜 DESCRIPTION 💜

This must be called from context that can sleep. 😴

ngl that's the whole description — but it's important! can-sleep context, not atomic context. she naps, she's allowed. don't call her somewhere she can't and then act surprised 🙈

---

🔥 RETURN 🔥

the crypto engine structure on success, else NULL. 🫶

so like, check it. if you get NULL she didn't slay that day, and you gotta handle it.

mwah 💋 that's the page. sourced from ./crypto, dated October 2026, and titled crypto_engin...init_and_set(9) because even manpage titles gotta truncate sometimes 😭 she's doing her best, and her best is iconic. bye bestie, go init that engine 🧚‍♀️💜
