STRUCT DPU_HW_SSPP_OPS(9)

💅 struct dpu_hw_sspp_ops(9) — like, the whole vibe

okay so bestie, welcome to struct dpu_hw_sspp_ops(9), straight outta the Kernel API Manual ✨ this is the group chat of function pointers that lets you talk to the SSPP hardware driver, and honestly? she's iconic for it.

🌸 NAME 🌸

struct dpu_hw_sspp_ops — the interface to the SSPP Hw driver functions 🫶

Two rules before you touch anything, no cap:

• Caller must call the init function to get the pipe context for each pipe.
• Assumption (and you know what happens when you assume, bestie) is that these functions will be called after clocks are enabled ⚡

---

✨ SYNOPSIS ✨

struct dpu_hw_sspp_ops {
    void (*setup_format)(struct dpu_sw_pipe *pipe, const struct msm_format *fmt, u32 flags);
    void (*setup_rects)(struct dpu_sw_pipe *pipe, struct dpu_sw_pipe_cfg *cfg);
    void (*setup_pe)(struct dpu_hw_sspp *ctx, struct dpu_hw_pixel_ext *pe_ext);
    void (*setup_sourceaddress)(struct dpu_sw_pipe *ctx, struct dpu_hw_fmt_layout *layout);
    void (*setup_csc)(struct dpu_hw_sspp *ctx, const struct dpu_csc_cfg *data);
    void (*setup_solidfill)(struct dpu_sw_pipe *pipe, u32 color);
    void (*setup_multirect)(struct dpu_sw_pipe *pipe);
    void (*setup_sharpening)(struct dpu_hw_sspp *ctx, struct dpu_hw_sharp_cfg *cfg);
    void (*setup_qos_lut)(struct dpu_hw_sspp *ctx, struct dpu_hw_qos_cfg *cfg);
    void (*setup_qos_ctrl)(struct dpu_hw_sspp *ctx, bool danger_safe_en);
    bool (*setup_clk_force_ctrl)(struct dpu_hw_sspp *ctx, bool enable);
    void (*setup_histogram)(struct dpu_hw_sspp *ctx, void *cfg);
    void (*setup_scaler)(struct dpu_hw_sspp *ctx, struct dpu_hw_scaler3_cfg *scaler3_cfg, const struct msm_format *format);
    void (*setup_cdp)(struct dpu_sw_pipe *pipe, const struct msm_format *fmt, bool enable);
 };

like, look at her. fourteen pointers. each one a little main character 🎀

💖 setup_format

sets up the pixel format and the cropping rectangle and the flip — a triple threat, honestly

• pipe: Pointer to software pipe context
• cfg: Pointer to pipe config structure
• flags: Extra flags for format config

💖 setup_rects

sets up the pipe ROI rectangles 📐

• pipe: Pointer to software pipe context
• cfg: Pointer to pipe config structure

💖 setup_pe

sets up the pipe pixel extension ✨

• ctx: Pointer to pipe context
• pe_ext: Pointer to pixel ext settings

💖 setup_sourceaddress

sets up the pipe source addresses — this is the one that actually tells the hardware where the buffer lives, so she's kind of a big deal 🧚

• pipe: Pointer to software pipe context
• layout: format layout information for programming buffer to hardware

💖 setup_csc

sets up color space coversion 🎨 (yes, that's spelled exactly like that in the original, we stan a typo)

• ctx: Pointer to pipe context
• data: Pointer to config structure

💖 setup_solidfill

enables/disables colorfill 🌈

• pipe: Pointer to software pipe context
• const_color: Fill color value
• flags: Pipe flags

💖 setup_multirect

sets up multirect configuration 👯 (two pipes, one vibe)

• pipe: Pointer to software pipe context

💖 setup_sharpening

sets up sharpening 🔪✨ crisp edges only

• ctx: Pointer to pipe context
• cfg: Pointer to config structure

💖 setup_qos_lut

sets up QoS LUTs 📊

• ctx: Pointer to pipe context
• cfg: LUT configuration

💖 setup_qos_ctrl

sets up QoS control 🎛️

• ctx: Pointer to pipe context
• danger_safe_en: flags controlling enabling of danger/safe QoS/LUT

ngl the name danger_safe_en is sending me 💀 but it's literally the flag name, don't touch it.

💖 setup_clk_force_ctrl

sets up clock force control ⏰ — and heads up bestie, this one actually returns a bool, she's built different

• ctx: Pointer to pipe context
• enable: enable clock force if true

💖 setup_histogram

sets up histograms 📈

• ctx: Pointer to pipe context
• cfg: Pointer to histogram configuration

💖 setup_scaler

sets up scaler 🦋 (scaler3 era, we love an upgrade)

• scaler3_cfg: Pointer to scaler configuration
• format: pixel format parameters

💖 setup_cdp

sets up client driven prefetch 🚀 iykyk

• pipe: Pointer to software pipe context
• fmt: format used by the sw pipe
• enable: whether the CDP should be enabled for this pipe

alright bestie, that's the whole page, you ate that 💅 this lil drop came from ./drivers/gpu/drm/msm/disp/dpu1, dated October 2026, serving struct dpu_hw_sspp_ops(9) realness. go forth and configure your pipes, and remember: init first, clocks on second, slay always 💜🫶
