In previous codes, the bridge is owned by hypervsior if there is pre-launched VM configured. This can cause bug, e.g. the net card behind the bridge cannot get IP because the write to bridge's command register to set BusMaster bit is ignored. This patch is to refine the codes to make the bridge be managed by Service VM if the device behind the bridge is not assigned to pre-launched VM. Furthermore, it adds the parent device into struct pci_pdev to construct PCI hierarchy. Tracked-On: #8849 Signed-off-by: Yi Sun <yi.y.sun@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/
