Add a API to sanitize vm_configs[] array, in this API, we will do sanity check for VM configurations and refill some fields in vm_configs[]. If sanity check is failed, the HV would reject to boot. About pcpu_bitmap of SOS_VM: We should not hard code pcpu_bitmap for SOS_VM, this is not convenient for unconfigured boards. The pcpu_bitmap follows a very simple rule: All physical CPUs except ocuppied by Pre-launched VMs are all belong to SOS_VM. In this way, the pcpu_bitmap of a SOS_VM is decided by pcpu_bitmap status in PRE_LAUNCHED_VMs. To get the correct pcpu_bitmap of SOS_VM, We need to setup another rule, that the vm_configs[] array should follow the order of PRE_LAUNCHED_VM - SOS_VM strictly. With this patch enabled, the pcpu_bitmap field of sos vm config is not needed to configure; Tracked-On: #2291 Signed-off-by: Victor Sun <victor.sun@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com> |

ACRN Hypervisor ############### 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”. The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on the bare-metal hardware, and is suitable for a variety of IoT and embedded device solutions. The ACRN hypervisor addresses the gap that currently exists between datacenter hypervisors, and hard partitioning hypervisors. The ACRN hypervisor architecture partitions the system into different functional domains, with carefully selected guest OS sharing optimizations for IoT and embedded devices. You can find out more about Project ACRN on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`ACRN Hypervisor`: https://github.com/projectacrn/acrn-hypervisor .. _`Project ACRN documentation`: https://projectacrn.github.io/
