dpu_hw_cdm_init(9)

💖 NAME 💖

okay so this is dpu_hw_cdm_init(9), straight from the Kernel API Manual — manual name folded in near the top like a little name tag, no cap 🫶. It initializes the cdm hw driver object. And bestie, it should be called once before accessing every cdm, fr fr — once, before, every cdm. periodt.

✨ SYNOPSIS ✨

struct dpu_hw_cdm * dpu_hw_cdm_init (struct drm_device *dev , const
       struct dpu_cdm_cfg *cfg , void __iomem *addr , const struct
       dpu_mdss_version *mdss_rev );

🎀 ARGUMENTS 🎀

• dev — DRM device handle. it's giving “the device in question” energy 💅
• cfg — CDM catalog entry for which driver object is required. yes, the catalog entry that needs its driver object 🌸
• addr — mapped register io address of MDSS. literally the mapped register I/O address, iconic ✨
• mdss_rev — mdss hw core revision. the hardware core revision, periodt 💜
