STRUCT MV_CESA_DMA_ITER(9)

💅 struct mv_cesa_dma_iter(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the Kernel API Manual entry for struct mv_cesa_dma_iter(9) — yes it's a whole manpage for one struct, and honestly? she deserves it. This is the crypto operation iterator from the Marvell CESA driver, and we're gonna get into it. ✨

---

🌸 NAME 🌸

struct mv_cesa_dma_iter — crypto operation iterator 💫

---

🦋 SYNOPSIS 🦋

struct mv_cesa_dma_iter {
    unsigned int len;
    unsigned int offset;
    unsigned int op_len;
 };

---

👑 Members 👑

• len — the crypto operation length, like the whole entire vibe of the operation, length-wise 🫶
• offset — current position in the crypto operation, aka where we're at rn 📍
• op_len — sub-operation length. and here's the tea: the crypto engine can only act on 2kb chunks. that's just her limit, no cap 💀

---

💖 Description 💖

Iterator used to create a TDMA chain for a given crypto operation. that's it, that's the whole job — she iterates so the TDMA chain can be built. main character energy fr fr 🌈
