STRUCT DPU_HW_DSC_OPS(9)

🦋 struct dpu_hw_dsc_ops(9) 🦋

okay so this is from the Kernel API Manual, bestie, and it's literally the whole interface to the dsc hardware driver functions 💅

✨ NAME ✨

struct dpu_hw_dsc_ops — the interface to the dsc hardware driver functions, fr fr. and the assumption baked in here? these functions get called after the clocks are enabled 😌 like, clocks on first, then we talk. no cap.

🌸 SYNOPSIS 🌸

struct dpu_hw_dsc_ops {
    void (*dsc_disable)(struct dpu_hw_dsc *hw_dsc);
    void (*dsc_config)(struct dpu_hw_dsc *hw_dsc, struct drm_dsc_config
*dsc, u32 mode, u32 initial_lines);
    void (*dsc_config_thresh)(struct dpu_hw_dsc *hw_dsc, struct
drm_dsc_config *dsc);
    void (*dsc_bind_pingpong_blk)(struct dpu_hw_dsc *hw_dsc, enum
dpu_pingpong pp);
 };

🎀 Members 🎀

• dsc_disable — disables dsc 💀 and yeah, hw_dsc is the pointer to the dsc context, obviously.
• dsc_config — configures the dsc encoder, slay ✨ hw_dsc is the pointer to the dsc context, dsc is the panel dsc parameters, mode is the dsc topology mode to be set, and initial_lines is the amount of initial lines to be used. so many little details and we love that for us 🫶
• dsc_config_thresh — programs the panel thresholds 👑 hw_dsc is the pointer to the dsc context, dsc is the panel dsc parameters.
• dsc_bind_pingpong_blk — binds pixel output from a DSC block to a pingpong block 🦋 like matchmaking but for hardware blocks, iykyk.
