Create two arrays for emulated MSRs: - guest_msrs[] in struct acrn_vcpu_arch: emulation for all MSRs that are included in emulated_guest_msrs[]. - world_msrs[] in struct cpu_context: it has separate copies for secure and normal world for those MSRs that are in the first NUM_WORLD_MSRS entries in emulated_guest_msrs[]. Split vmsr.c/emulated_msrs[] into 3 smaller arrays: - emulated_guest_msrs[]: corresponding MSRs are emulated in guest_msrs[] - mtrr_msrs[]: emulated MTRRs are saved in vMTRR module - unsupported_msrs[]: GP for any guest accesses Tracked-On: #1867 Signed-off-by: Zide Chen <zide.chen@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/
