STRUCT SA_CTX_INFO(9)

🦋 struct sa_ctx_info(9) 🦋

okay so bestie, welcome to the Kernel API Manual ✨ today we're gonna talk about struct sa_ctx_info — literally the SA context information struct, no cap. this is the one from ./drivers/crypto/sa2ul.h, October 2026 edition, and she is iconic 💅

---

🌸 NAME 🌸

struct sa_ctx_info — SA context information. that's it, that's the whole vibe check 🎀

---

✨ SYNOPSIS ✨

struct sa_ctx_info {
    u8 *sc;
    dma_addr_t sc_phys;
    u16 sc_id;
    u16 cmdl_size;
    u32 cmdl[SA_MAX_CMDL_WORDS];
    struct sa_cmdl_upd_info cmdl_upd_info;
    u32 epib[SA_DMA_NUM_EPIB_WORDS];
 };

like, look at her. so structured. so organized. main character energy fr fr 👑

💖 Members 💖

okay now the part you actually came for, the field-by-field breakdown, let's GO 🏃‍♀️💨

• sc — Pointer to security context 🔐 like, a literal pointer to the security context, bestie. it's giving "here's where the good stuff lives."
• sc_phys — Security context physical address that is passed on to SA2UL 📬 this is the physical address of the security context, and it gets handed straight over to SA2UL. iykyk.
• sc_id — Security context ID 🏷️ the ID number of the security context. everyone needs an identity, periodt.
• cmdl_size — Command label size 📏 the size of the command label. simple, clean, slaying.
• cmdl — Command label for a particular iteration 🔁 the command label for a particular iteration — not all iterations, a particular one. pay attention bestie 🙈
• cmdl_upd_info — structure holding command label updation info 📝 literally exactly what it says: the structure that holds the command label updation info. no notes. ate. 💅
• epib — Extended protocol information block words 🧚 the extended protocol information block words. say that five times fast, i dare you 😭
