  1. ACRN project update
  1. “ACRN Power Management Introduction” by YIN, Fengwei
Download foil from ACRN Presentation->WW25’20
Description: We will refresh power management in ACRN 2.0 design. In ACRN 2.0, the power management was re-designed to fit Industrial use case requirement, both for CPU sharing and C/P status management need be updated.
  1. All: Community open discussion.
Q1: Could User OS reject the system shutdown request from SOS:  NO, only one exception of RTVM may still run, then hypervisor will decide and maybe not full system shutdown.
Q2: CPU governor is in hypervisor to control CPU sharing case: vCPU C/P is disabled in VM. But for CPU partition mode, the governor is owned by guest OS totally.
