Hi Hans, I forgot there is another difference, PRIME solution has to copy screen once before display to iGPU while MS_ALL_IN_ONE don't have to and can display what full screen app draws directly by page flip (for DRI2) which may be important for embedded platforms with week GPU and limited memory bandwidths.
Benefit from common interface of drm/gbm/egl, may be modesetting can play a bigger role of span multi drm devices to give more optimization like this and: 1. multi render node, a single protocol screen to accept request and dispatch to each render node for render 2. multi display node associate with the render node (some display node has the same drm device with render node), so no need to handle bo tile-linear copy and each render node can handle request of its related display node.
