STRUCT DPU_CDM_CFG(9)

✨ struct dpu_cdm_cfg(9) ✨

okay so bestie, we're in the Kernel API Manual, section 9, and this is the whole glow-up for struct dpu_cdm_cfg. it's a little struct that carries info about chroma down blocks 💅 that's the entire personality, and honestly? she's iconic for it.

---

🌸 NAME 🌸

struct dpu_cdm_cfg — information of chroma down blocks

and the one-liner keeps rolling, because the NAME line also hands you the fields, so let's give them their moment ✨

• @name — a string name, there purely for debug purposes 🫶
• @id — an enum identifying this block 👑
• @base — the register offset of this block 📍

---

🦋 SYNOPSIS 🦋

struct dpu_cdm_cfg {
    DPU_HW_BLK_INFO;
 };

that's it. that's the whole struct definition. one macro line, zero notes, maximum main character energy 😌 no cap, the DPU_HW_BLK_INFO macro is doing all the heavy lifting here.

---

🎀 Members 🎀

not me about to list the members and… there are none listed 😭 the Members section of this page is genuinely empty, fr fr. everything you get is the DPU_HW_BLK_INFO from the synopsis plus the @name, @id and @base blurbs up in NAME. that's the vibe check result: nothing more documented here 💀

and that's the page, periodt 💖 big mwah to whoever keeps this thing — it lives in ./drivers/gpu/drm/msm/disp/dpu1 and it's dated October 2026, so yeah, freshly served 🍓 struct dpu_cdm_cfg(9), out 🫶
