✨ drm_for_each_plane_mask ✨

okay so this is drm_for_each_plane_mask(9) from the Kernel API Manual, and bestie, it's literally the macro that loops over planes for you 💅

---

🌸 NAME 🌸

drm_for_each_plane_mask — iterate over planes specified by bitmask

Like, it walks the planes for you. That's the whole vibe. 🦋

---

🎀 SYNOPSIS 🎀

drm_for_each_plane_mask (plane , dev , plane_mask );

---

💖 ARGUMENTS 💖

• plane — the loop cursor 👀 this is the variable that's gonna hold each plane as you go around the loop, so it's very much the main character here.
• dev — the DRM device 🖥️ your whole graphics device situation.
• plane_mask — bitmask of plane indices 🎚️ which planes you actually wanna visit, encoded as a mask.

---

🌈 DESCRIPTION 🌈

Iterate over all planes specified by bitmask. That's it, that's the whole thing — the mask tells it which planes, and it goes over them one by one. no cap, simple and iconic ✨
