*	drm/i915/gvt: vGPU display virtualization	Zhi Wang	2016-10-14	1	-0/+6
\| \| \| \| \| \| \| \| \| \| \| \| \|	This patch introduces the GVT-g display virtualization. It consists a collection of display MMIO handlers, like power well register handler, pipe register handler, plane register handler, which will emulate all display MMIOs behavior to support virtual mode setting sequence for guest.

*	drm/i915/gvt: vGPU interrupt virtualization.	Zhi Wang	2016-10-14	1	-0/+223
	This patch introduces vGPU interrupt emulation framework. The vGPU intrerrupt emulation framework is an event-based interrupt emulation framework. It's responsible for emulating GEN hardware interrupts during emulating other HW behaviour. It consists several components: - Descriptions of interrupt register bit - Upper level <-> lower level interrupt mapping - GEN HW IER/IMR/IIR register emulation routines - Event-based interrupt propagation interface When a GVT-g component wants to inject an interrupt to a VM during a emulation, first it should specify the event needs to be emulated and the framework will deal with the rest of emulation: - Generating related virtual IIR bit according to virtual IER and IMRs, - Generate related virtual upper level virtual IIR bit accodring to the per-platform interrupt mapping - Injecting a MSI to VM Signed-off-by: Zhi Wang <zhi.a.wang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
