we added uefi stub for hv, and want vm0 continue running under uefi env to boot other uefi payload (osloader or bzImage). during this, the uefi timer irq need be handled elegantly. there are 3 types for uefi timer: 1. 8254 based on IRQ0 of PIC 2. HPET based on IOAPIC 3. HPET based on MSI currently, we only support type 3 (HPET+MSI). But we are following a in-correct flow to handle this timer interrupt: - we set VMX_ENTRY_INT_INFO_FIELD directly if a timer interrupt happened before vcpu launching, this will make its vlapic mess up, which finally cause hpet timer stop. this patch remove this in-correct approach, the new approach patch will be followed by next patch.

Embedded-Hypervisor ################### This open source embedded hypervisor defines a software architecture for running multiple software subsystems managed securely on a consolidated system (by means of a virtual machine manager), and defines a reference framework Device Model implementation for devices emulation This embedded hypervisor is type-1 reference hypervisor, running directly on the system hardware. It can be used for building software defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running on Intel Architecture Apollo Lake platforms. As a reference implementation, it provides the basis for embedded hypervisor vendors to build solutions with an open source reference I/O mediation solution, and provides auto makers a reference software stack for SDC usage. This embedded hypervisor is able to support both Linux* and Android* as a Guest OS, managed by the hypervisor, where applications can run. This embedded hypervisor is a partitioning hypervisor reference stack, also suitable for non-automotive IoT & embedded device solutions. It will be addressing the gap that currently exists between datacenter hypervisors, hard partitioning hypervisors, and select industrial applications. Extending the scope of this open source embedded hypervisor relies on the involvement of community developers like you!
