doc_read_page_ecc_init(9)

✨ NAME ✨

okay so this is doc_read_page_ecc_init(9) from the Kernel API Manual, and she is here to initialize hardware ECC engine 💅✨ bestie, it's giving kernel-core main character energy fr fr.

---

🌸 SYNOPSIS 🌸

the signature is literally this, no edits, no cap:

int doc_read_page_ecc_init (struct docg3 *docg3 , int len );

---

🎀 ARGUMENTS 🎀

• docg3 — the device 🫶
• len — the number of bytes covered by the ECC (BCH covered) 🔥

---

💖 DESCRIPTION 💖

The function does initialize the hardware ECC engine to compute the Hamming ECC (on 1 byte) and the BCH hardware ECC (on 7 bytes) ✨ ngl that's the whole vibe: Hamming on 1 byte, BCH hardware ECC on 7 bytes, periodt.

Return 0 if succeeded, -EIO on error 😭💀 like, success is 0, error is -EIO, and that's the tea.
