kmb_ecc_do_scalar_op(9)

💅 kmb_ecc_do_scalar_op(9)

okay so bestie, welcome to the Kernel API Manual page for kmb_ecc_do_scalar_op — literally the function that makes the OCS ECC hardware do a scalar operation for you. no cap, this is the good stuff ✨

---

✨ NAME ✨

kmb_ecc_do_scalar_op — perform a Scalar operation using the OCS ECC HW. that's it, that's the vibe 🎀

---

🌸 SYNOPSIS 🌸

int kmb_ecc_do_scalar_op (struct ocs_ecc_dev *ecc_dev , u64 *scalar_out
, const u64 *scalar_a , const u64 *scalar_b , const struct ecc_curve
*curve , unsigned int ndigits , const u32 inst );

yeah she's got seven parameters, we love a thorough queen 👑

---

🦋 ARGUMENTS 🦋

• ecc_dev — the OCS ECC device you're gonna use. like, the actual hardware bestie 🫶
• scalar_out — where you store the output scalar. the ~results~ go here 💖
• scalar_a — input scalar operand a. main character energy, she goes first.
• scalar_b — input scalar operand b. (yes the original has no period on this one, we respect the punctuation choices of our ancestors ✨)
• curve — the curve on which the operation is performed. everything happens on a curve, iykyk 🌈
• ndigits — the size of the operands, measured in digits. yes, digits. don't @ me 💅
• inst — the operation to perform, passed in as an OCS ECC instruction. you pick the move, she executes it 🔥

---

⭐ RETURN ⭐

0 on success, and a negative error code otherwise. so like, if you get 0 you're slaying, and if it's negative… not slaying 😭

go read those too, they're all iconic in their own right 💜

ngl, the operands and the output are all <yellow>u64 *</yellow> pointers, so mind your ndigits before you go poking around memory. treat her with respect 🙈

and that's the whole page, bestie! this one lives over in ./drivers/crypto/intel/keembay, and it was dated October 2026 — so yeah, keep that in mind, and go forth and do your scalar ops 💅🎀🦋 periodt 🌸✨
