STRUCT CCP_ECC_ENGINE(9)

💅 struct ccp_ecc_engine(9) — the CCP ECC operation, bestie ✨

Okay so this is a page from the Kernel API Manual, and it's all about struct ccp_ecc_engine — literally the struct that holds your CCP ECC operation info. It's giving "small struct, big responsibilities" 🎀

---

🌸 SYNOPSIS 🌸

Here's the whole vibe, verbatim:

struct ccp_ecc_engine {
    enum ccp_ecc_function function;
    struct scatterlist *mod;
    u32 mod_len;
    union {
      struct ccp_ecc_modular_math mm;
      struct ccp_ecc_point_math pm;
    } u;
    u16 ecc_result;
 };

---

✨ Members ✨

• function — which ECC function you're gonna perform 👑
• mod — the ECC modulus, iykyk
• mod_len — length in bytes of the modulus, fr fr
• ecc_result — the result of the ECC operation 💖

---

🦋 Description 🦋

These are the variables you literally have to have set when you call ccp_enqueue_cmd:

• function, mod, mod_len
• operand, operand_len, operand_count, output, output_len, output_count
• ecc_result

Like, no cap — all of those. Don't skip any 🫶

Heads up bestie: the union in there holds either a struct ccp_ecc_modular_math mm or a struct ccp_ecc_point_math pm — it's one or the other, that's the whole point of a union 💀
