Display lists contain lists of registers and associated values to be applied atomically by the hardware. They lower the pressure on interrupt processing delays when reprogramming the device as settings can be prepared well in advance and queued to the hardware without waiting for the end of the current frame. Display list support is currently limited to the DRM pipeline.
