This patchset adds overlay and cursor plane support. It also fixes some issues uncovered during implementation of this. However, the plane updates currently causes the display to flicker for unknown reasons. As far as I can tell, the CRTC atomic_flush should trigger the update correctly via READREG, which according to documentation: The READREG bit causes a single transfer to begin at the next frame blanking period. This bit is cleared when the transfer is complete. I made a video how that looks: https://cloud.agner.ch/index.php/s/Yfqa2u7UBEWUT8N Any ideas?
