This patch makes use of IA32_PAT MSR to emulate cache disabled behaviour When the guest is requesting to set CR0.CD: - Keep guest's CR0.CD and CR0.NW bits unchanged - Write IA32_PAT MSR with all-UC entries to change the effective memory type for all GPA to UC for the guest VCPU - It depends on trapping wrmsr to IA32_PAT to prevent any entry in IA32_PAT being changed to non UC type by the guest When the guest is requesting to clear CR0.CD: - restore the content of guest's IA32_PAT MSR Signed-off-by: Zide Chen <zide.chen@intel.com> Acked-by: Eddie Dong <eddie.dong@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!
