STRUCT MV_CESA_SG_DMA_ITER(9)

💅 NAME 💅

struct mv_cesa_sg_dma_iter — scatter-gather iterator. This cutie is from the Kernel API Manual, section 9, and it is lowkey giving “tiny helper struct with main character energy.” 🫶✨

✨ SYNOPSIS ✨

struct mv_cesa_sg_dma_iter {
    enum dma_data_direction dir;
    struct scatterlist *sg;
    unsigned int offset;
    unsigned int op_offset;
 };

🎀 Members 🎀

• dir — transfer direction. Literally which way the data is headed, bestie. 💫
• sg — scatter list. The list itself, no cap. 📋
• offset — current position in the scatter list. Like the tiny cursor inside the list. ✨
• op_offset — current position in the crypto operation. The spot we’re at in the crypto op. 🎯

💖 Description 💖

Okay so here’s the vibe: this iterator is used to iterate over a scatterlist while creating a TDMA chain for a crypto operation. That’s the whole serve — it’s the little walker doing the loop so the TDMA chain can get built. 💅✨
