For cross-VM S5 notify via vUART, life_mngr service is running on UOS. It is listening on /dev/ttyS1 to get SOS's commands. The protocol is: SOS send "shutdown", UOS feedback "acked". When SOS triggle shutdown, SOS can 1) check VM's status until UOS stopped, 2) retry shutdown UOS normally with timeout. So, no matter life_mngr server is running, SOS's shutdown procedure will properly finish. Tracked-On: #3564 Signed-off-by: fuyanX <yanx.fu@intel.com> Acked-by: Yan, Like <like.yan@intel.com>
ACRN tools ########## The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the "ACRN Device Model". This folder holds the source to a number of tools that facilitate the management, debugging, profiling, and logging of multi-OS systems based on ACRN. You can find out more about Project ACRN and its set of tools on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`Project ACRN documentation`: https://projectacrn.github.io/
