drm_atomic_plane_check(9)

🌸 NAME 🌸

drm_atomic_plane_check — check plane state. This is the drm_atomic_plane_check(9) page from the Kernel API Manual, and it's literally here to check plane state, bestie 💅✨

✨ SYNOPSIS ✨

int drm_atomic_plane_check (const struct drm_plane_state
*old_plane_state , const struct drm_plane_state *new_plane_state );

🎀 ARGUMENTS 🎀

• old_plane_state — old plane state to check. It's the before pic of the plane state, and yes, we're checking it 🫶
• new_plane_state — new plane state to check. The new plane state, ready for its check-up ✨

🦋 DESCRIPTION 🦋

Okay so this one provides core sanity checks for plane state. That's the whole plot: core sanity checks, plane state, no cap. It's giving "is this state okay?" energy, and that's iconic 💖

🔥 RETURN 🔥

0 on success — slay. On failure, you get an error code. So: zero on success, error code on failure, periodt 💅
