In current code, vpci do the pci enumartion and add pci devices to the context table of iommu. Need to enable iommu DMA address translation later than vpci init. Otherwise, in UEFI platform, there will be a shot time that address translation is enabled, but the context table is not setup. For the devices active in UEFI environment will have problem on address translation. Tracked-On: #3160 Signed-off-by: Binbin Wu <binbin.wu@intel.com> Acked-by: Anthony Xu <anthony.xu@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/
