STRUCT GDD_TRN(9)

💖 struct gdd_trn(9) 💖

okay so this is a page from the Kernel API Manual, and bestie, it's a short one — literally the whole thing fits in a snack break. It's about struct gdd_trn, aka the GDD transaction data. Tiny struct, big main character energy. ✨

---

🌸 NAME 🌸

struct gdd_trn — the GDD transaction data 💅

---

✨ SYNOPSIS ✨

Here's the whole vibe, copy-pasted exactly because we do not improvise code:

struct gdd_trn {
    struct hsi_msg          *msg;
    struct scatterlist      *sg;
 };

Two pointers, that's the entire struct. Lowkey minimal, highkey iconic. 🎀

---

🫶 Members 🫶

okay so let's meet the two members, they're the whole cast:

• msg — pointer to the hsi_msg that's being served rn 🍓
• sg — pointer to the current sg entry that's being served rn 🌸

fr fr that's it, two pointers doing their thing. No cap. 💀

---

🌈 SEE ALSO 🌈

go look at these if you wanna understand the whole ecosystem, iykyk:

• kernel file ./drivers/hsi/controllers/omap_ssi.h — struct omap_ssm_ctx(9)
• struct omap_ssi_port(9)
• struct omap_ssi_controller(9)

like, the header file and the two struct pages. the friend group. the squad. 👑

---

bestie reminder: this page is literally just a struct definition + two one-line member descriptions, so if you were waiting for a plot twist — there is none. 🙈

---

and that's the whole page! 🦋 this little cutie lives in ./drivers/hsi/controllers and the manual's dated October 2026 — so go forth, read your pointers, and slay 💅🔥👑
