STRUCT DPU_HW_DITHER_CFG(9)

💅 struct dpu_hw_dither_cfg(9) 💅

okay so this is a page from the Kernel API Manual, bestie — and we're talking about struct dpu_hw_dither_cfg, no cap. It's the dither feature structure and honestly she's giving "tiny struct, big main character energy." ✨

✨ NAME ✨

struct dpu_hw_dither_cfg — the dither feature structure 🎀

---

🌸 SYNOPSIS 🌸

struct dpu_hw_dither_cfg {
    u64 flags;
    u32 temporal_en;
    u32 c0_bitdepth;
    u32 c1_bitdepth;
    u32 c2_bitdepth;
    u32 c3_bitdepth;
    u32 matrix[DITHER_MATRIX_SZ];
 };

like, that's the whole vibe. seven members, one of them is an array, we love to see it 🫶

🦋 Members 🦋

let's do a little roll call, one by one, because every single field deserves her moment 💖

• flags — for customizing operations. that's the little switchboard for tweaking stuff, iykyk.
• temporal_en — temperal dither enable. (yes, "temperal" — that's literally what the page says, i'm just the messenger 🙈)
• c0_bitdepth — the c0 component bit depth ⭐
• c1_bitdepth — the c1 component bit depth ⭐
• c2_bitdepth — the c2 component bit depth ⭐
• c3_bitdepth — the c2 component bit depth 👀 (not me noticing it says c2 again — that's exactly how it's written on the page, so i'm passing it straight to you, fr fr)
• matrix — the dither strength matrix 🔥 she's an array of DITHER_MATRIX_SZ, and she holds the strength. iconic.

go check out the kernel file ./drivers/gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.h, plus these two besties:

• struct dpu_hw_pingpong_ops(9)
• to_dpu_hw_pingpong(9)

lowkey reminder: every field name, type and value up there is copy-pasted straight from the source page — don't go renaming anything, bestie, the compiler will NOT be cute about it 💀

and that's the whole page, periodt. 🧚 this little slice of kernel lore lives in ./drivers/gpu/drm/msm/disp/dpu1, dated October 2026 — catch you in the next struct dpu_hw_dither_cfg(9), mwah! 💅🌈💖
