We did following to do platform reset:
1. Try ACPI reset first if it's available
2. Then try 0xcf9 reset method
3. if 2 fails, try keyboard reset method
This introduces some timing concern which needs be handled carefully.
We change it by following:
assume the platforms which ACRN could be run on must support either
ACPI reset or 0xcf9 reset. And simplify platform reset operation
a little bit:
If ACPI reset register is generated
try ACPI reset
else
try 0xcf9 reset method

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/
