knelson@lynx.com, For OceanSound Partners: Notice the indication of virtual machine (VM) types: Application VM Guest environment primarily used to host applications. Lynx Software Technologies - Crunchbase Company Profile & Funding Careers at Lynx Software Technologies This is FreeRTOS (Amazon) and AzureRTOS (Microsoft). A maximum of 4095 VLANs per trunk interface are supported. And, since you have the OS guaranteed to be uncorrupted, you should build in ways to recover if the disk does get corrupted (scripts, the chkdsk utility, etc, called programmatically from your application). It is important to note that for every device assignment, the hypervisor guarantees that the impact of hazardous events created by devices such as erroneous DMA and interrupt pre-emption, is constrained to the VM assigned to the device, protecting the integrity and timing of the other VMs. Given LynxSecures support of Arm Cortex A53 and A72 cores, the base fundamentals are in place to support a broad range of nVidias product portfolio. SOI 1 Planning Document Set: SOI 2 Requirement and Design Document Set: The documentation set is dependent on the product components that need to be certified. Can you share details on your use of 3D diagrams? Linux fits into LYNX MOSA.ic in two ways. Follow View all. Lynx does provide components from which a secure boot system can be built. Can you be more specific about the compatibility to ARINC that LynxOS-178 includes? LynxSecure was designed to satisfy real-time, high assurance computing requirements used to regulate military and industrial computing environments, such as NIST, NSA Common Criteria, and NERC CIP. Lynx Simple Applications (bare-metal applications) currently have tool chain support based on GCC. It over-writes the OS image of the VM to be replaced and then makes a hypercall to reboot it which picks up and launches the new OS image. Lynx does not guarantee the accuracy of the information herein beyond the date of publication. There are several open source unikernels available? Each exec file has access to the POSIX API as well as the ARINC API. Over 30 years of processor evolution, Lynx has crafted and adapted platform architectures for builders of safety- and security-critical software systems. On Xilinx the ATF (Arm Trusted Firmware) is used to control which parts of the SoC (CPU cores and FPGA) have access to which peripherals and memory. The Luminosity IDE from Lynx Software Technologies utilizes the Eclipse IDE as a framework and extends it through proprietary plugins. LynxOS-178 provides the following system service groups in accordance with the ARINC 653-1 standard: Partition Management, Process Management, Time Management, Inter-partition Communication (Sampling and Queuing Ports), Intra-partition Communication (Buffers, Blackboards, Semaphores, and Events), and Health Monitoring. Software can be in an ARINC 653 partition and not use ARINC ports. In our opinion, the introduction of a unikernel reduces the number of use cases where companies need bare metal applications. Application environments can be (1) bare-metal; (2) RTOS, Windows, or other 3rd-Party OS; (3) Linux. After that, the application has direct access to those resources it has been permitted to use. It also controls which SMC (system management calls), like program FPGA, the hypervisor and other parts of the SoC are allowed to make. We have a how-to for x86 that describes how to digitally sign the LynxSecure binary and add keys to the BIOS to enable secure boot. Lynx Software Technologies (Lynx) products and services fall under the jurisdiction of the U.S. Department of Commerce Export Administration Regulations (EAR). Solutions related to security are very SoC specific and dependent on key storage, cryptographic accelerators, and more. As Lynx starts to broaden its footprint in markets beyond aerospace, we continue to evaluate the right partnerships and components to align with our technology. Skadden, Arps, Slate, Meagher & Flom LLP served as legal counsel to OceanSound. The separation is achieved by hardware virtualization, which once configured, does not require active management (emulation, scheduling, etc). [18], LYNX MOSA.ic's use of multi-core processors supports hardware virtualization. FreeRTOS is the most widely used real-time operating system in the embedded industry. Lynx has no control over this part of the boot sequence. How is the architecture configuration policy set up? 20 comments Add a Comment [deleted] 3 yr. ago Lynx is a reseller of Interactive Brokers. Additionally, the system allows multiple applications of differing criticality levels within partitions to execute, completely isolated, on the same hardware resource. January 5, 2023 6:00:00 AM PST. The selection of Lynxs core platform in the Department of Defenses largest and most important program is a testament to the robustness of Lynxs core technology and validates their growth potential, said Joe Benavides, Managing Partner of OceanSound. Some factors that can greatly affect that boot time: Overall size and number of Guest OS subjects configured to run on the system, Number of physical devices used and assigned to Guest OS subjects in the system configuration, The best resource to address this question is this technical white paper. LynxOS-178 drivers are separate binaries that are loaded at boot time. Bosch VHIT (Italy) Partners with Lynx Software Technologies - GlobeNewswire We are engaged with several semiconductor companies under NDA to understand their RISC-V based product plans. That binary is self-contained and configures the target resources as described in your model immediately on power-on. It is expected that the system is setup to load the kernel and, lets say, 5 custom applications from a RAM disk. Commonly, critical security functionsuch as a crypto algorithm, or data filterand a unique information flow configuration must be established and protected to achieve a secure system. Secure partitioning evidence is provided as part of our airworthiness artifacts required to satisfy the DO-178C DAL A and DO-356A SAL 3 objectives. Lynx Software Technologies is the premier Mission Critical Edge company that enables safe, secure and high-performance environments for global customers in aerospace and automotive, enterprise. Lynx Software Technologies is funded by 10 investors. The privileged setup code is discarded (for security) so that all that is left of LynxSecure is a set of event handlers to respond to and redirect interrupts and handle management calls like shutdown. Independent application modules are isolated, static virtual machine environments (and their guests) created by the separation kernel which enable system architects to simplify their system designs by better managing software complexity inheritance. Lynx Software Technologies Jul 2021 - Present2 years United States System Administrator II S&A Associates (Placed at UBER) Mar 2019 - Sep 20212 years 7 months Palo Alto, California, United States. For over 30 years, Lynx Software Technologies has enabled designs in security and safety critical markets including aviation/avionics, transportation, medical and defense systems. This example shares address 8000 of the PCI device NET0.IOMEM0 as a 0x1000 long memory region called NET0.TIMESYSNCREGS. CREATE_SAMPLING_PORT and WRITE_SAMPLING_MESSAGE are Sampling Port Services service requests, Queuing Port Services: A queuing port is a communication object allowing a partition to access a channel of communication configured to operate in queuing mode. Senior Principal Engineer, Chairman for Multicore for Avionics Working Group. The hypervisor only understands serial ports, VGA text-mode display, EHCI USB debugging (no USB stack), the virtualization technologies and control of the various system busses, including PCI. A simpler way to build robust software systems. The LynxOS-178 RTOS conforms to the ARINC 653-1 Application Executive Software (APEX) Interface defined by the ARINC 653-1 standard. Lynx Software Technologies, Inc. It features predictable worst-case response time, preemptive scheduling, real-time priorities, ROMable kernel, and memory locking. We use the Intel RDT (resource director technology) CAT (cache allocation technology) feature to split the last level cache. Autoconfig looks at the subject (guest VM) names and, where not explicitly set, uses heuristics to allocate a sensible quantity of RAM, choose the subject type (paravirt, fullvirt) and CPU core to place the VM onto. Dynamic VM (also referred to as dynamic segmented boot may be combined with multiple hypervisor schedules to allow a set of VMs to be staged with new OS images and then launched via a schedule switch. As a Platinum honoree, LYNX MOSA.ic for Avionics was recognized as a superb innovation characterized by a groundbreaking approach to meeting a need and/or a new level of performance, efficiency, ease of use or other beneficial quality. Buildroot, which is provided as part of LYNX MOSA.ic, or a 3rd party COTS OS (e.g. [24][25] Lynx Software Technologies released LYNX MOSA.ic for Industrial on the Microsoft Azure marketplace in 2021.[12]. Once loaded into memory, the first stage bootloader will jump to and hand-off control of the system to LynxSecure.

Lynx uses open source and open standards in many places. It's available for users with the operating system Windows 2000 and previous versions, and it is available in . For additional information, contact us at inside@lynx.com. The standard operation of PTP is that it continuously disciplines (adjusts) slave clocks to keep them accurate with the master. This is not available yet, but it means: Extend the LynxOS-178 network stack to support PTP. ARINC 653 Partition Management: services related to partition management. Find the press release here. Lynx offers a DoD Risk Management Framework guide to aid the US Armys security evaluation of the security enforcing properties of the platform. We have gone to 3D as we think it helps showcase the differences of our approach. It defines the CPU schedule for the partitions, how much RAM each gets, what FS each has and what device nodes are visible. SaaS, Android, Cloud Computing, Medical Device), Where the organization is headquartered (e.g. Lynxs modular, open, and interoperable products are well-positioned to meet the requirements of the most demanding applications. This is the F-35 Lightning II, which will replace various tactical aircraft. If a guest fails to strobe the watchdog in the permitted window of time the separation kernel will trigger a policy exception event. Mission computers need other options to prioritize certain sub-elements that have challenging real-time deterministic requirements. The Common Criteria remains a useful standard, but no further SKPP evaluations will be accepted, and the SKPP is effectively dead. It does exactly what is required, it directly shares the PTP HW Clock registers with other VMs within a single target. Unikernels can provide APIs (Lynxs product supports POSIX for example) which makes it simpler for developers to build applications. Most of our recent focus has been on supporting the Intel C3708 processor (previously known as Denverton). At the 79th Annual Forum of the Vertical Flight Societys 79th (May 2023), a paper proposed definitions for software modules, operating system properties and key technologies for two distinct Software Operating Environment (SOE): This was a collaborative paper developed by companies that includes Collins Aerospace, JHNA, Lynx, Parry Labs, RTI and US Army PEO.Lynx isnt allowed to share this paper, but interested readers can find some additional information here. How does certification of a separation kernel hypervisor differ from a traditional hypervisor? Obviously this OS only runs on x86 platforms. LynxSecure provides the following reference monitor features: Lynx developed Xilinx FPGA assisted boot and credential protection prototypes to serve as exemplar of fundamental boot and system initialization security design elements. To learn more about separation kernels and how they are distinct from RTOS-based hypervisors, read: "What is a Separation Kernel?". Once the SoC has an accurate PTP clock, PCI BAR sharing is used to give other VMs access the timer registers. What, then, are "independent application modules?". Follow View all. The goal of a separation kernel is to be minimal, elegant and efficient (LynxSecure is 15K on Arm). The RAM assigned to the VM is still present and is able to receive DMA transactions even when the VM is NOT currently scheduled on the CPU core. Are Lynx products and services subject ITAR controls? Can LynxElement run directly on hardware? It also controls which SMC (system management calls), like program FPGA, the hypervisor and other parts of the SoC are allowed to make. No one company can deliver all technologies for the next generation of securely-connected mission critical platforms. It is offered as a software module for LynxOS-178. Lynx embraced open standards from its inception, with its original RTOS, LynxOS, featuring a UNIX-like user model and standard POSIX interfaces to embedded developers.

On Xilinx the ATF (Arm Trusted Firmware) is used to control which parts of the SoC (CPU cores and FPGA) have access to which peripherals and memory. Audit Event Manager;: the kernel contains a runtime state transition manager that can change the execution behavior of the system when a policy exception event occurs. Lynxs software, services, documentation, data, and other information about the Lynx Software Technologies software are commercial items as that term is defined in U.S. 48 CFR 2.101. Setting up secure boot is target specific. Rapid Integration of Mixed-Criticality Components, Maximum Reuse of Trusted Certified Code Bases. No one company can deliver all technologies for the next generation of securely-connected mission critical platforms. Is that set up contained within the system or is it external? LynxOS has been deployed in millions of embedded devices and has operated reliably for 30+ years across multiple safety- and security-critical embedded markets. LynxCoding is a division of LCSI (Logo Computer Systems Inc.) of Montreal, Canada. The PDI approach helps minimize LynxSecure's source lines of code (SLOC) count while enabling cost-effective certification of customer specific VM configurations.
