💖 qcom_ice_import_key(9) 💖

okay so bestie, welcome to the Kernel API Manual page for qcom_ice_import_key(9) — yes that's the whole title, yes it's a lot, stay with me 🫶

---

✨ NAME ✨

qcom_ice_import_key — Import a raw key for inline encryption 👑

---

🌸 SYNOPSIS 🌸

int qcom_ice_import_key (struct qcom_ice *ice , const u8 *raw_key ,
       size_t raw_key_size , u8 lt_key[BLK_CRYPTO_MAX_HW_WRAPPED_KEY_SIZE] );

like, that's the whole signature, no cap ✨

---

🎀 ARGUMENTS 🎀

• ice — ICE driver data 💅 that's your driver's whole situation, the context basically
• raw_key — the raw key to import 🔑 the actual key, in the raw, coming in hot
• raw_key_size — size of raw_key in bytes, fr fr you gotta tell it how big the key is
• lt_key — output buffer for the long-term wrapped key 🎁 this is where the result goes, it's an output buffer so like… it gets filled in

---

🦋 DESCRIPTION 🦋

Use HWKM to import a raw key and return it as a long-term wrapped key ⭐ that's the whole vibe: raw key goes in, long-term wrapped key comes out. iconic behavior honestly.

---

🔥 RETURN 🔥

the size of the resulting wrapped key on success; -errno on failure 💀 so on the good path you get a size (a number, a positive one, we love that), and on the bad path you get a negative errno, as one does 😭
