STRUCT OCS_HCU_CTX(9)

💅 struct ocs_hcu_ctx(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a little struct called struct ocs_hcu_ctx, and honestly? it's giving OCS HCU Transform context energy. that's the whole vibe. no cap. 🦋

---

✨ NAME ✨

struct ocs_hcu_ctx — the OCS HCU Transform context. that's it, that's the name, slay 💅

---

🎀 SYNOPSIS 🎀

here's the whole glow-up, laid out exactly like this:

struct ocs_hcu_ctx {
    struct ocs_hcu_dev *hcu_dev;
    u8 key[SHA512_BLOCK_SIZE];
    size_t key_len;
    bool is_sm3_tfm;
    bool is_hmac_tfm;
 };

like, look at her. five members. main character struct fr fr 👑

🌸 Members 🌸

• hcu_dev — the OCS HCU device that this transformation is using. she's the hardware bestie doing the actual work 💖
• key — the key 🔑 and heads up: it's only used for HMAC transformations. so if you're not doing HMAC, this field is just chilling there, decorative, living its truth 🙈
• key_len — the length</... wait no, the length of the key. one job. she does it. periodt 💅
• is_sm3_tfm — a bool that says whether or not this is an SM3 transformation. yes-or-no vibes only 🌈
• is_hmac_tfm — a bool that says whether or not this is a HMAC transformation. also yes-or-no. also iconic. ⭐

ngl bestie, read the actual source before you go poking at these fields — the manpage gives you the map, not the whole treasure chest 🫶

okay that's the whole page!! mwah 💋 this little beauty lives over in ./drivers/crypto/intel/keembay, dated October 2026, and she answers to the name struct ocs_hcu_ctx(9). go forth and be a crypto icon 🔥👑🎀
