ACRN Device Model Architecture Introduction, we will talk about what is device model, device model booting flow and how to emulate a device in device model.
  1. All: Community open discussion.
Q1: in SOS, one VHM char driver interfaces for all Device models OR independent VHM char path for an each DM?
A: Only one VHM to handle devices for each DM with different handles, but same path.
Q2. What is the security model on Request Buffer shared memory ? 
A: It's shared between DM, VHM and hypervisor, so attack may impact target VM. The threat may come from SOS.
Q3. Can support 32bit guest VM.    A: Yes. 
Q4. DM populates the pci_vdev_ops structure based on the parameters passed to the acrn_dm, right?
A: Yes, The devices will be registered only when they are specified in DM command line parameters.
