Abstract: In an embodiment, an operating system provides a port group service that permits two or more ports to be bound together as a port group. A thread may listen for messages and/or events on the port group, and thus may receive a message/event from any of the ports in the port group and may process that message/event. Threads that send messages/events (“sending threads”) may send a message/event to a port in the port group, and the messages/events received on the various ports may be processed according to a queue policy for the ports in the port group. Messages/events may be transmitted to from the ports to a listening thread (a “receiving thread”) using a receive policy that determines the priority at which the receiving thread is to execute to process the message/event.

Abstract: In an embodiment, a memory manager for a privileged program in an electronic system may manage multiple memory pools having different attributes. The memory manager may provide memory objects drawn from a memory pool or memory pool slice to various memory requestors (e.g. user space threads/programs, etc.). By ensuring that the memory pool slices/memory objects are isolated from each other (e.g. non-overlapping memory ranges, for example), the memory manager may ensure the protection of address spaces of different programs. Additionally, various attributes and permissions for the memory pool slices/memory objects may be controlled by the memory manager.
