Project ACRN hypervisor
Add the VCAT_ENABLED element to RDTType so that user can enable/disable vCAT globally Add the GUEST_FLAG_VCAT_ENABLED guest flag to enable/disable vCAT per-VM. Currently we have the following per-VM clos element in scenario file for RDT use: <clos> <vcpu_clos>0</vcpu_clos> <vcpu_clos>0</vcpu_clos> </clos> When the GUEST_FLAG_VCAT_ENABLED guest flag is not specified, clos is for RDT use, vcpu_clos is per-CPU and it configures each CPU in VMs to a desired CLOS ID. When the GUEST_FLAG_VCAT_ENABLED guest flag is specified, vCAT is enabled for this VM, clos is for vCAT use, vcpu_clos is not per-CPU anymore in this case, just a list of physical CLOSIDs (minimum 2) that are assigned to VMs for vCAT use. Each vcpu_clos will be mapped to a virtual CLOSID, the first vcpu_clos is mapped to virtual CLOSID 0 and the second is mapped to virtual CLOSID 1, etc Add xs:assert to prevent any problems with invalid configuration data for vCAT: If any GUEST_FLAG_VCAT_ENABLED guest flag is specified, both RDT_ENABLED and VCAT_ENABLED must be 'y' If VCAT_ENABLED is 'y', RDT_ENABLED must be 'y' and CDP_ENABLED must be 'n' For a vCAT VM, vcpu_clos cannot be set to CLOSID 0, CLOSID 0 is reserved to be used by hypervisor For a vCAT VM, number of clos/vcpu_clos elements must be greater than 1 For a vCAT VM, each clos/vcpu_clos must be less than L2/L3 COS_MAX For a vCAT VM, its clos/vcpu_clos elements cannot contain duplicate values There should not be any CLOS IDs overlap between a vCAT VM and any other VMs Tracked-On: #5917 Signed-off-by: dongshen <dongsheng.x.zhang@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com> |

Project ACRN Embedded Hypervisor ################################ .. raw:: html <img src="doc/images/ACRN_Logo_PrimaryLockup_COLOR-300x300-1.png" height="175px" align="right"> 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. .. start_include_here Community Support ***************** The Project ACRN Developer Community includes developers from member organizations and the general community all joining in the development of software within the project. Members contribute and discuss ideas, submit bugs and bug fixes. They also help those in need through the community's forums such as mailing lists and IRC channels. Anyone can join the developer community and the community is always willing to help its members and the User Community to get the most out of Project ACRN. Welcome to the project ARCN community! We're now holding monthly Technical Community Meetings and encourage you to call in and learn more about the project. Meeting information is on the `TCM Meeting page`_ in our `ACRN wiki <https://wiki.projectacrn.org/>`_. .. _TCM Meeting page: https://github.com/projectacrn/acrn-hypervisor/wiki/ACRN-Committee-and-Working-Group-Meetings#technical-community-meetings Resources ********* Here's a quick summary of resources to find your way around the Project ACRN support systems: * **Project ACRN Website**: The https://projectacrn.org website is the central source of information about the project. On this site, you'll find background and current information about the project as well as relevant links to project material. For a quick start, refer to the `Introduction`_ and `Getting Started Guide`_. * **Source Code in GitHub**: Project ACRN source code is maintained on a public GitHub repository at https://github.com/projectacrn/acrn-hypervisor. You'll find information about getting access to the repository and how to contribute to the project in this `Contribution Guide`_ document. * **Documentation**: Project technical documentation is developed along with the project's code, and can be found at https://projectacrn.github.io. Additional documentation is maintained in the `Project ACRN GitHub wiki`_. * **Issue Reporting and Tracking**: Requirements and Issue tracking is done in the Github issues system: https://github.com/projectacrn/acrn-hypervisor/issues. You can browse through the reported issues and submit issues of your own. * **Reporting a Potential Security Vulnerability**: If you have discovered potential security vulnerability in ACRN, please send an e-mail to acrn-security@lists.projectacrn.org. It is important to include the following details: - The projects and versions affected - Detailed description of the vulnerability - Information on known exploits * **Mailing List**: The `Project ACRN Development mailing list`_ is perhaps the most convenient way to track developer discussions and to ask your own support questions to the project ACRN community. There are also specific `ACRN mailing list subgroups`_ for builds, users, and Technical Steering Committee notes, for example. You can read through the message archives to follow past posts and discussions, a good thing to do to discover more about the project. .. _Introduction: https://projectacrn.github.io/latest/introduction/ .. _Getting Started Guide: https://projectacrn.github.io/latest/getting-started/ .. _Contribution Guide: https://projectacrn.github.io/latest/contribute.html .. _Project ACRN GitHub wiki: https://github.com/projectacrn/acrn-hypervisor/wiki .. _PGP Key: https://www.intel.com/content/www/us/en/security-center/pgp-public-key.html .. _vulnerability handling guidelines: https://www.intel.com/content/www/us/en/security-center/vulnerability-handling-guidelines.html .. _Project ACRN Development mailing list: https://lists.projectacrn.org/g/acrn-dev .. _ACRN mailing list subgroups: https://lists.projectacrn.org/g/main/subgroups
