Download foil from ACRN Presentation->ACRN_TCM->WW11’20
Short description: ACRN overview, building block breakdown and module introduction, such as arch, boot flow, memory layout, interrupt flow, pass-through device, I/O request, instruction emulation, APIC emulation, MSR emulation, debug..
  1. All: Community open discussion.
Q&A: 
Q1: How to secure Safety VM not impacted when other VM crashes, with inter-VM communication enabled. There is dedicated mechanism to secure Safety VM always safe and not impacted, especially from functional safety perspective.
Q2. Any power management inside ACRN 2.0 hypervisor :  yes, similar with ACRN1.0 arch for system management. 
Q3. In ACRN Boot: DSP running on AP0 during the boot-up, after that, AP0 could handle SOS or other VMs, same with AP1/2.
Q4.Does  IPI/LAPIC need go through hypervisor to RTVM?:  No, RT VM will directly get LAPIC to secure Real Time performance.
