STRUCT DPU_HW_CDM_OPS(9)

💖 NAME 💖

okay bestie, welcome to the struct dpu_hw_cdm_ops(9) page from the Kernel API Manual ✨ This is the interface to the chroma down Hw driver functions — and the big assumption is that these functions will be called after clocks are enabled 🫶

✨ SYNOPSIS ✨

       struct dpu_hw_cdm_ops {
           int (*enable)(struct dpu_hw_cdm *cdm, struct dpu_hw_cdm_cfg *cfg);
           void (*bind_pingpong_blk)(struct dpu_hw_cdm *cdm, const enum
       dpu_pingpong pp);
        };

• enable — Enable the CDM module 💅 cdm is a pointer to chroma down context. The synopsis signature is int (*enable)(struct dpu_hw_cdm *cdm, struct dpu_hw_cdm_cfg *cfg); so yeah, cfg is literally right there too 👑
• bind_pingpong_blk — Enable/disable the connection with pingpong 🦋 cdm is a pointer to chroma down context, and pp is the pingpong block id. The full signature above has the const enum dpu_pingpong pp situation going on, no cap 😭
