Uday Kiran Pichika 9823ea4ed2 modesetting: Lay the foundation for enabling VRR ... These changes have been ported from AMD GPU DDX driver. This patch adds support for setting the CRTC variable refresh property for suitable windows flipping via the Present extension. In order for a window to be suitable for variable refresh it must have the _VARIABLE_REFRESH property set by the MESA and inform Modesetting DDX driver with window property updates. Then the window must pass the checks required to be suitable for Present extension flips - it must cover the entire X screen and no other window may already be flipping. And also DRM connector should be VRR capable. With these conditions met every CRTC for the X screen will have their variable refresh property set to true. Kernel Changes to support this feature in I915 driver is under development. Tested with DOTA2, Xonotic and custom GLX apps.
