Currently vlapic_build_id() uses vcpu_id to retrieve the lapic_id per_cpu variable: vlapic_id = per_cpu(lapic_id, vcpu->vcpu_id); SOS vcpu_id may not equal to pcpu_id, and in that case it runs into problems. For example, if any pre-launched VMs are launched on PCPUs whose IDs are smaller than any PCPU IDs that are used by SOS. This patch fixes the issue and simplify the code to create or get vapic_id by: - assign vapic_id in create_vlapic(), which now takes pcpu_id as input argument, and save it in the new field: vlapic->vapic_id, which will never be changed. - simplify vlapic_get_apicid() by returning te saved vapid_id directly. - remove vlapic_build_id(). - vlapic_init() is only called once, merge it into vlapic_create().

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/
