set_xex_data_unit_size(9)

💅 set_xex_data_unit_size — Kernel API Manual energy ✨

Okay bestie, welcome to the Kernel API Manual — this one's a tiny little helper from the crypto corner of the kernel and honestly? She's short but she matters. 🎀

---

✨ NAME ✨

set_xex_data_unit_size — sets the data unit size for XEX mode, and it lives right there in data_out_addr[15:0]. That's it, that's the gig. 💖

---

🌸 SYNOPSIS 🌸

void set_xex_data_unit_size (struct cc_hw_desc *pdesc , u32 size );

No cap, that's the whole signature. Look at her. Iconic. 👑

---

🦋 ARGUMENTS 🦋

• pdesc — a pointer to the HW descriptor struct. Like, the actual descriptor you're poking at. 🫶
• size — the data unit size for XEX mode. That's the number you're tucking in. ✨

Lowkey a reminder that this page gives you exactly what the descriptor field wants — nothing more, nothing less. Don't go inventing extra behaviour, bestie, the manpage didn't say it. 💀
