Current code enables IOMMU from init_iommu_vm0_domain which is called from vm0/sos boot sequence. For partition mode VMs, this is not called as VMs are numbered from 1. This patch adds support to initialize root table pointer for each IOMMU and enable all IOMMUs from init_iommu. Hence IOMMUs are enabled even though ACRN does not boot vm0. This patch also has changes to fix #1270. Tracked-On: #1246 #1270 Signed-off-by: Sainath Grandhi <sainath.grandhi@intel.com>
Embedded-Hypervisor ################### This open source embedded hypervisor defines a software architecture for running multiple software subsystems managed securely on a consolidated system (by means of a virtual machine manager), and defines a reference framework Device Model implementation for devices emulation This embedded hypervisor is type-1 reference hypervisor, running directly on the system hardware. It can be used for building software defined cockpit (SDC) or In-Vehicle Experience (IVE) solutions running on Intel Architecture Apollo Lake platforms. As a reference implementation, it provides the basis for embedded hypervisor vendors to build solutions with an open source reference I/O mediation solution, and provides auto makers a reference software stack for SDC usage. This embedded hypervisor is able to support both Linux* and Android* as a Guest OS, managed by the hypervisor, where applications can run. This embedded hypervisor is a partitioning hypervisor reference stack, also suitable for non-automotive IoT & embedded device solutions. It will be addressing the gap that currently exists between datacenter hypervisors, hard partitioning hypervisors, and select industrial applications. Extending the scope of this open source embedded hypervisor relies on the involvement of community developers like you!
