Customer might have specific folder where stores their own configurations for their customized scenario/board, so add TARGET_DIR parameter to support option that build hyprvisor with specified configurations. So valid usages are: (target = all | hypervisor) 1. make <target> 2. make <target> KCONFIG_FILE=xxx [TARGET_DIR=xxx] 3. make <target> BOARD=xxx SCENARIO=xxx [TARGET_DIR=xxx] 4. make <target> BOARD_FILE=xxx SCENARIO_FILE=xxx [TARGET_DIR=xxx] 5. make <target> KCONFIG_FILE=xxx BOARD_FILE=xxx SCENARIO_FILE=xxx [TARGET_DIR=xxx] If TARGET_DIR parameter is not specified in make command, hypervisor will be built with board configurations under hypervisor/arch/x86/configs/ and scenario configurations under hypervisor/scenarios/. Moreover, the configurations would be overwritten if BOARD/SCENARIO files are specified in make command. If TARGET_DIR parameter is specified in make command, hypervisor will be built with configuration under that folder if no BOARD/SCENARIO files are specified. When BOARD/SCENARIO files are available in make command, the TARGET_DIR is used to store configurations that BOARD/SCENARIO file provided, i.e. Configurations in TARGET_DIR folder will be overwritten.

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/
