Abstract

A mechanism for the creation of a shared memory aperture between modes in a parent and child partition is described. The shared memory aperture can be created between any memory mode between the guest and any host. For example, a shared memory aperture can be created between the kernel mode on the child partition and the user mode on the parent partition.
