dm_plane_col...eline_active(9)

🌸 NAME 🌸

Hey bestie 💖 welcome to the Kernel API Manual! This page is dm_plane_col...eline_active(9), and the function it’s hyping up is dm_plane_color_pipeline_active. It checks if a plane’s color pipeline is active.

---

✨ SYNOPSIS ✨

No cap, here’s the signature exactly as it is:

bool dm_plane_color_pipeline_active (struct drm_atomic_commit *state ,
struct drm_plane *plane , bool use_old );

---

🫶 ARGUMENTS 🫶

Okay so the parameters are giving:

• state — DRM atomic state
• plane — DRM plane to check
• use_old — if true, inspect the old colorop states; otherwise the new ones

---

💅 DESCRIPTION 💅

A color pipeline may be selected (color_pipeline != NULL) but still is inactive if every colorop in the chain is bypassed. It only returns true when at least one colorop has bypass == false, meaning the cursor would be subjected to the transformation in native mode.

---

🔥 RETURN 🔥

true if the pipeline modifies pixels, false otherwise. Periodt.
