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>
