Currently when get_rsdp is called, the EFI depriv_boot env is not initialized. In such case it will fallback to the legacy mechanism of ACPI table. If the ACPI table based on legacy mechanism is not found, it will fail to get the ACPI table and then the system will hang. On the old platform it still can parse the ACPI table from legacy mechanism. In fact when EFI RSDP exists, the EFI RSDP is preferred instead of legacy ACPI RSDP. In order to avoid multiple calling of depriv_init_boot, the init_boot_operations is renamed and called after X2apic is enabled(early_init_lapic).

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/
