The current code only supports 2 HPA regions per VM. This patch extended ACRN to support 2+ HPA regions per VM, to use host memory better if it is scatted among multiple regions. This patch uses an array to describe the hpa region for the VM, and change the logic of ve820 to support multiple regions. This patch dependent on the config tool and GPA SSRAM change Tracked-On: #6690 Signed-off-by: Chenli Wei <chenli.wei@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/
