This patch makes the Service OS bootloader configurable by passing
a command-line argument to 'acrn.efi' when setting up the EFI
bootloader using, e.g., 'efibootmgr'. If no argument is passed, the
default bootloader used is: "\EFI\org.clearlinux\bootloaderx64.efi".
This is the default bootloader/setting used by Clearlinux and is set
in the bsp/uefi/include/bsp/bsp_cfg.h file (via the
CONFIG_UEFI_OS_LOADER_NAME define)
The general format of the argument is: "bootloader=<\path\to\bootloader>".
As a concrete example, imagine the following set-up:
* You have installed the Service OS (bare-metal for now)
* Bootloader is "\EFI\org.clearlinux\bootloaderx64.efi"
* Boot device is '/dev/sda'
* EFI System Partition (ESP) is '1'
* You put the ACRN hypervisor under "\EFI\acrn\"
To change the default boot entry to boot the ACRN hypervisor, enter:
# efibootmgr -c -l "\EFI\acrn\acrn.efi" -d /dev/sda -p 1 \
-L "ACRN Hypervisor" -u "bootloader=\EFI\org.clearlinux\bootloaderx64.efi"
And reboot your machine.

Embedded-Hypervisor ################### This open source embedded hypervisor defines a software architecture for running multiple software subsystems managed securely on a consolidated system (by means of a virtual machine manager), and defines a reference framework Device Model implementation for devices emulation This embedded hypervisor is type-1 reference hypervisor, running directly on the system hardware. It can be used for building software defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running on Intel Architecture Apollo Lake platforms. As a reference implementation, it provides the basis for embedded hypervisor vendors to build solutions with an open source reference I/O mediation solution, and provides auto makers a reference software stack for SDC usage. This embedded hypervisor is able to support both Linux* and Android* as a Guest OS, managed by the hypervisor, where applications can run. This embedded hypervisor is a partitioning hypervisor reference stack, also suitable for non-automotive IoT & embedded device solutions. It will be addressing the gap that currently exists between datacenter hypervisors, hard partitioning hypervisors, and select industrial applications. Extending the scope of this open source embedded hypervisor relies on the involvement of community developers like you!
