Currently ept_pages_info[] is initialized with first element only that force VM of id 0 using SOS EPT pages. This is incorrect for logical partition and hybrid scenario. Considering SOS_RAM_SIZE and UOS_RAM_SIZE are configured separately, we should use different ept pages accordingly. So, the PRE_VM_NUM/SOS_VM_NUM and MAX_POST_VM_NUM macros are introduced to resolve this issue. The macros would be generated by acrn-config tool when user configure ACRN for their specific scenario. One more thing, that when UOS_RAM_SIZE is less then 2GB, the EPT address range should be (4G + PLATFORM_HI_MMIO_SIZE).

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/
