STRUCT DPU_MERGE_3D_CFG(9)

✨ NAME ✨

struct dpu_merge_3d_cfg — ok bestie so this is literally the info-about-DSPP-blocks struct 💅 and inside it there's @id (the enum identifying this block), @base (the register offset of this block), and @sblk (the sub-blocks information). That's the whole vibe check, no cap ✨

🦋 SYNOPSIS 🦋

struct dpu_merge_3d_cfg {
    DPU_HW_BLK_INFO;
    const struct dpu_merge_3d_sub_blks *sblk;
 };

So iconic. DPU_HW_BLK_INFO; is just doing its thing in there (it's a macro, she's built different), and then sblk is a const pointer to struct dpu_merge_3d_sub_blks — literally the sub-block info, 🎀

🌈 Members 🌈

ngl, this heading is here in the original but it's serving absolutely nothing — it's empty, bestie 🫶 No members listed underneath it. Moving on, main character energy only.

👑 SEE ALSO 👑

Kernel file ./drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h — that's where all of this lives, iykyk 💖

🍓 Little sign-off cutie: this page is from ./drivers/gpu/drm/msm/disp/dpu1, dated October 2026, and it's struct dpu_merge_3d_cfg(9) from the Kernel API Manual. Slay, go touch some registers 💜
