Present SGX related MSRs to guest if SGX is supported. - MSR_IA32_SGXLEPUBKEYHASH0 ~ MSR_IA32_SGXLEPUBKEYHASH3: SGX Launch Control is not supported, so these MSRs are read only. - MSR_IA32_SGX_SVN_STATUS: read only - MSR_IA32_FEATURE_CONTROL: If SGX is support in VM, opt-in SGX in this MSR. - MSR_SGXOWNEREPOCH0 ~ MSR_SGXOWNEREPOCH1: The two MSRs' scope is package level, not allow guest to change them. Still leave them in unsupported_msrs array. Tracked-On: #3179 Signed-off-by: Binbin Wu <binbin.wu@intel.com> Acked-by: Eddie Dong <eddie.dong@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/
