An electronic device includes a memory and at least one processor coupled to the memory. The at least one processor is configured to identify a device change event in a host operating system, wherein the host operating system includes a host namespace, switch from the host namespace to a container namespace of a container, and update the container with information based on the device change event.

System and method for dynamic volume management

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.

System and method for guest operating system using containers

This disclosure relates to an electronic device including a memory and at least one processor coupled to the memory. The at least one processor is configured to execute a daemon process in one of a container or a host operating system, wherein the daemon process is configured to manage data transfer between the container and the host operating system, create, via the daemon process, an inter-process communication (IPC) channel between the container and the host operating system, receive incoming audio data, and buffer the incoming audio data to the IPC channel.

System and method for device audio

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.

System and method for frame buffer

An apparatus and method for protecting kernel data integrity in an electronic device are provided. The method includes mapping a specified type of data to a read-only memory area, detecting a write attempt to the specified type of data, determining whether a process attempting to write to the specified type of data is permitted according to a specified condition, and allowing the write attempt if the process attempting to write to the specified type of data satisfies the specified condition.
