ACRN hypervisor should trap guest doing PCI AF FLR. Besides, it should save some status before doing the FLR and restore them later, only BARs values for now. This patch will trap guest Conventional PCI Advanced Features Control Register write operation if the device supports Conventional PCI Advanced Features Capability and check whether it wants to do device AF FLR. If it does, call pdev_do_flr to do the job. Tracked-On: #3465 Signed-off-by: Li Fei1 <fei1.li@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/
