  • Patent number: 11042398
    Abstract: A method for operating an electronic device, the method including spawning a name space tool (NST) as part of a boot process of a host OS, wherein the NST is a process with a plurality of root privileges of the host OS. The method further includes spawning, by the NST, a container for a guest OS, wherein the container for the guest OS is mapped to a dedicated domain in the host OS, and dropping, by the NST, a root privilege of the host OS in response to spawning the container for the guest OS.

  • Patent number: 10733096
    Abstract: A method for implementing a shared memory buffer includes at an apparatus comprising a processor and a physical memory, running a host environment with a host virtual memory. The method further includes running a guest environment with a guest virtual memory, performing, by the host environment, an allocation of a frame buffer in the physical memory, and mapping the allocated frame buffer into the host virtual memory. Additionally, the method includes passing a handle of the allocated frame buffer to the guest environment and performing a mapping of the allocated frame buffer into the guest virtual memory, the mapping based on the handle of the allocated frame buffer.

  • Patent number: 10686776
    Abstract: A connected device includes an application processor, a secure element, and a control module. The application processor is configured to receive a control command from an electronic device. The secure element is connected between the application processor and a control module and is configured to authenticate the control command. The control module is configured to receive the control command when the control command is authenticated by the secure element, execute the control command to activate at least one function of the connected device, and transmit a response to the electronic device.
