[Intel-gfx] [RFCv2 PATCH 00/14] gvt: Hacking i915 for GVT context requirement

[Wang, Zhi A]

Hi Kevin:
	Now our context switch is covered by context status change notification handler. In the status change handler we will save render registers. As GVT context will be a single submission context we will restore the render registers when the GVT context is scheduled-out by HW.
