💖 versal_pm_aes_enc_update(9) 💖

okay bestie, so this is a page straight out of the Kernel API Manual — yes, that Kernel API Manual — and today's main character is versal_pm_aes_enc_update. buckle up, it's giving cryptography but make it cute 🎀

✨ NAME ✨

versal_pm_aes_enc_update — the function that goes and talks to the AES hardware to encrypt your data, using the AES-GCM core. literally it's the encryption glow-up 💅

---

🦋 SYNOPSIS 🦋

int versal_pm_aes_enc_update (const u64 in_params , const u64 in_addr );

that's the whole vibe. two u64s in, one int out, no cap ✨

---

🌸 ARGUMENTS 🌸

• in_params — the address of the AesParams structure 🫶 like, this is where all the config lives
• in_addr — the address of the input buffer 💖 this is the actual data you're feeding in

---

⭐ RETURN ⭐

returns a status — either success or an error code. that's it. that's the tea 🍓

heads up bestie: it's a status return, so pls actually check it, okay? 😭
