There can be times when user unknowinlgy enables CONFIG_CAT_ENBALED SW flag, but the hardware might not support L3 or L2 CAT. In such case software can end up writing to the CAT MSRs which can cause undefined results. The patch fixes the issue by enabling CAT only when both HW as well software via the CONFIG_CAT_ENABLED supports CAT. The patch also address typo with "clos2prq_msr" function name. It should be "clos2pqr_msr" instead. PQR stands for platform qos register. Tracked-On: #3715 Signed-off-by: Vijay Dhanraj <vijay.dhanraj@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/
