The length of the ACPI data entry in ve820 tab was 960K, while the ACPI file is 1MB. It would cause ept unmapped fault when loading the pre-launched VMs. This patch changes it to 1MB to fix the problem. And the ACPI data length was missed when calculating ENTRY_HPA1_LOW_PART2 length. Fixed here too. The vACPI data and NVS entry size for pre-launched VM is currently hard-coded. Add VIRT_ACPI_DATA_LEN and VIRT_ACPI_NVS_LEN to replace them. And build connection with their starting address, too. Tracked-On: #6507 Signed-off-by: Zhou, Wu <wu.zhou@intel.com> Reviewed-by: Victor Sun <victor.sun@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/
