It is found that SOS will reset the PCI devices under PCI bridge 00:1c.0 when 00:1c.0 is exposed to SOS. If a PCI device under 00:1c.0 is passed through to pre-launched VM, it will be reset by SOS at startup hence the passthrough will not work properly. This patch provides a workaround by hiding PCI bridge 00:1c.0 from SOS in this case. Tracked-On: #5346 Signed-off-by: Jian Jun Chen <jian.jun.chen@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/
