[PATCH v2 xserver 00/11] modesetting: MS_ALL_IN_ONE

[Yu, Qiang]

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.

Regards,
Qiang
