Project ACRN hypervisor
In the current design, hypervisor only detects two kinds of multiboot compiliant firwares (UEFI loader and non-UEFI loader), It can't detect other multiboot compliant firware (such GRUB loader) and can't detect UEFI loader explicitly since loader name is not supported by UEFI loader (efi stub). In the logical partition scenario on KBL NUC i7, one multiboot compliant firware is used to boot hypervisor and load guest OS image, and firware runtime service shall be disable to avoid interference. So GRUB can be selected as a candidate to enable logical partition scenario on KBL NUC i7. Update firware detection and operations selecting logic to detect more multiboot compiliant firware (such as GRUB and UEFI loader) explicitly, different operations is selected according to the boot load name through a static mapping table between boot load name and firmware operations. GRUB loader can use the SBL operations to handle multiboot information parsing and vm booting since these multiboot compiliant firmware (SBL/ABL/GRUB) which boots hypervisor (binary format), provides multiboot information and the start address of guest OS image(binary format) in the same way, and only runs on boot time. From MISRA C view, viarble array is not allowed, so define the static array for above mapping table; From security view, it is better use strncmp insteads of strcmp. TODO: In future, need to redesign boot moudle to suport different boot loader, different VM boot, and different guest OS. V2-->V3: Update firmware detection logic to handle GRUB loader which is need to provided multiboot information to the hypervisor (such as the address of guest OS image); V3-->V4: Update firmware detection and operations selecting logic to enable GRUB loader support in hypervisor; V4-->V5: Separte UEFI loader name supporting in a separate patch, and update commit comment to make patch clearer. V5-->V6: Update "Tracked-On" Tracked-On: #2944 Signed-off-by: Xiangyang Wu <xiangyang.wu@linux.intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com> |

Project ACRN Embedded 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. .. 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 weekly 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. * **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 .. _Project ACRN Development mailing list: https://lists.projectacrn.org/g/acrn-dev .. _ACRN mailing list subgroups: https://lists.projectacrn.org/g/main/subgroups
