摘要： 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.

摘要： 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.
