Abstract: Aspects of the disclosure provide for mechanisms for memory protection of virtual machines in a computer system. A first host page table and a second host page table is generated by a processing device running a hypervisor in view of a guest page table associated with a virtual machine. The first host page table includes a first mapping corresponding to a privileged page of a guest memory and a second mapping corresponding to an unprivileged page of the guest memory. The second host page table includes a third mapping corresponding to the unprivileged page of the guest memory. The first host page table is associated with the virtual machine. In response to detecting a transition from a first guest mode to a second guest mode by the virtual machine, the virtual machine is associated with the second page table.

Abstract: A method, apparatus, and system for displaying information for an aircraft on a display device in a flight deck of the aircraft. A computer system in the aircraft displays a dynamic home page in a graphical user interface on the display device in the flight deck of the aircraft. The information in the dynamic home page is based on the information used to operate the aircraft during a current phase of flight. The computer system changes the information in the dynamic home page as the current phase of flight changes or non-normal conditions occur during operation of the aircraft.

Abstract: Systems and methods for memory management for virtual machines. An example method may include generating, by a Peripheral Component Interconnect (PCI) device comprising an input/output memory management unit (IOMMU), a first bit sequence and generating a second sequence by applying a predetermined transformation to the first bit sequence. The method may then write the second bit sequence to a memory buffer, read a first value from the memory buffer, write the first bit sequence to the memory buffer, and read a second value from the memory buffer. Responsive to determining that the second value does not match the first value, the method may associate a writable attribute with an IOMMU page table entry associated with the memory buffer.

The machine vision processing unit is configured to process image data captured by the video cameras using stereoscopic and structure from motion techniques to detect an obstacle that is near or in the path of the aircraft. Estimates of the range to the object and the rate of change of that range are computed. With the range and range rate, a time to collision can be estimated toward every point of the aircraft. A pilot warning can be sounded based on the nearness of the potential collision. A method of calibrating the video cameras using existing feature points on the top of the aircraft is initiated in response to power being turned on.
