STRUCT SEC_HW_SGE(9)

✨ struct sec_hw_sge(9) ✨

okay bestie, welcome to the Kernel API Manual entry for struct sec_hw_sge — it's a kernel struct, it's from sec_drv.h, and it's literally just here to track each of the 64 element SEC HW SGL entries. sixty-four of them. iconic. 💅

---

🎀 NAME 🎀

struct sec_hw_sge — Track each of the 64 element SEC HW SGL entries.

like. that's the whole job. she tracks. she's the entry tracker. 🦋

---

🌸 SYNOPSIS 🌸

struct sec_hw_sge {
    dma_addr_t buf;
    unsigned int len;
    unsigned int pad;
 };

look at her. three members. no drama. no cap. 🔥

💖 Members 💖

• buf — the IOV dma address for this entry. that's the address, bestie, hold it gently 🫶
• len — length of this IOV. how much IOV. the size. the amount. ✨
• pad — reserved space. it's giving "don't touch, it's reserved" energy, so… don't touch it 🙈

lowkey a reminder that pad is reserved space — that's stated in the original and I'm not inventing anything, so just leave it alone, okay? 💀
