In current design, when pass-thru dev, for the PIO bar, need to ensure the guest PIO start address equals to host PIO start address. Then set the VMCS io bitmap to pass-thru the corresponding port io to guest for performance. ACRN-DM and acrn-config should ensure the identical mapping of PIO bar. If ACRN-DM or acrn-config failed to achieve this, we should deny the launch of VM Tracked-On: #6508 Signed-off-by: Liu,Junming <junming.liu@intel.com> Reviewed-by: Zhao Yakui <yakui.zhao@intel.com> Reviewed-by: Fei Li <fei1.li@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/
