Q1: Regarding to polling mode driver, will CPU become always busy?
A1: No. There’s a timer to trigger the polling periodically?
Q2: Guest VxWorks is working on ACRN’s Sharing Mode, right? Have you tried VxWorks in partional mode?
A2: Yes, currently VxWorks is working on share mode. In our ACRN 2.0 roadmap, we’ll support Zephyr as Safety VM in partition mode. We haven’t tried VxWroks in partition mode but it should be doable.
Q3: Can we boot VxWorks as Guest VM without additional patches to VxWork?
A4: Yes. The vanilla VxWorks can run on ACRN. The additional patches are to enable RT capability for VxWorks when running as Guest OS.
Q4: Which chip support ioapic passthrough?
A4: We passthrough local apic, not ioapic. Right now, it can support KBL, WSL platform.
  1. All: Community open discussion.
