dpu_hw_pingpong_init(9)

okay bestie, welcome to dpu_hw_pingpong_init(9) from the Kernel API Manual 💖 — this is the page for getting the pingpong driver initialized, and honestly it's giving "small function, important job" energy.

✨ NAME ✨

dpu_hw_pingpong_init is the function that initializes the pingpong driver for the pingpong catalog entry you passed in. That's the whole vibe: you bring the catalog entry, it gets the driver situation ready. 🎀

🦋 SYNOPSIS 🦋

struct dpu_hw_pingpong * dpu_hw_pingpong_init (struct drm_device *dev , const struct dpu_pingpong_cfg *cfg , void __iomem *addr , const struct dpu_mdss_version *mdss_rev );

🌸 ARGUMENTS 🌸

• dev — the corresponding device for devres management, bestie.
• cfg — the Pingpong catalog entry for which the driver object is required; yes, it's literally the catalog entry that needs its driver object.
• addr — the mapped register io address of MDP, so you know where the register action lives.
• mdss_rev — the dpu core's major and minor versions. Version check vibes, fr fr.

🎀 RETURN 🎀

You get back an error code or an allocated dpu_hw_pingpong context — those are the two outcomes, periodt. So check it, bestie; don't just assume it slayed. 💅
