STRUCT DPU_MDSS_VERSION(9)

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

okay bestie, so this is a page straight out of the Kernel API Manual, and it's about struct dpu_mdss_version. That's the little struct that holds DPU's major and minor versions — like, the whole personality of the DPU core in two tiny numbers. ✨

---

🌸 NAME 🌸

struct dpu_mdss_version — literally just DPU's major and minor versions, no cap 💖

---

✨ SYNOPSIS ✨

here's the shape of it, and yes she's smol:

struct dpu_mdss_version {
    u8 core_major_ver;
    u8 core_minor_ver;
 };

---

🦋 Members 🦋

two members, both iconic, both u8, both absolutely doing their job:

• core_major_ver — DPU core's major version 🎀 (the big-number energy)
• core_minor_ver — DPU core's minor version 🌸 (the little-number energy)

---

🔥 SEE ALSO 🔥

okay so this struct does not roll alone — she's part of a whole friend group, and you can find her filed under the Kernel file ./drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h. Here's the entire squad, and no I'm not skipping a single one, we don't do that here 💅:
