Currently, we always assign 0x3F8 as port base io address for emualted COM1 of SOS. But in some board, it use serial port which has other base io address for debugging purpose. And this serial port info is also exposed to SOS by ACPI table. In this case, SOS could access the debugging serial port because it could see the port from ACPI table and conflict with ACRN. To mitigate this issue, we could let emulated COM1 of SOS to use native debugging serial port base io port and irq info. Tracked-On: #4998 Signed-off-by: Yin Fengwei <fengwei.yin@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/
