🦋 dpu_hw_lm_init(9) — Kernel API Manual 🦋

hii bestie 💖 welcome to the dpu_hw_lm_init(9) page from the Kernel API Manual. This one is giving “small function, very important job” energy, so let’s get into it ✨

🎀 NAME 🎀

dpu_hw_lm_init — initializes the mixer hw driver object. It should be called once before accessing every mixer. periodt 💅

🛠️ SYNOPSIS 🛠️

struct dpu_hw_mixer * dpu_hw_lm_init (struct drm_device *dev , const struct dpu_lm_cfg *cfg , void __iomem *addr , const struct dpu_mdss_version *mdss_ver );

💬 ARGUMENTS 💬

okay so here’s the cast of characters, and yes they all matter 🫶

• dev — the corresponding device for devres management. it’s the device bestie in charge of devres stuff ✨
• cfg — the mixer catalog entry for which the driver object is required. like, which mixer are we setting up? this tells you 🔥
• addr — the mapped register io address of MDP. literally the address vibe check for MDP 💅
• mdss_ver — the DPU core’s major and minor versions. gotta know the version, no cap 👑
