Claim 7:
8. A system comprising:
a first subsystem comprising circuitry configured to map a first region of a first kernel address space to a first region in a first physical address space; and
a second subsystem comprising circuitry configured to map a first region of a second kernel address space to the first region in first physical address space, wherein the second subsystem is configured to map the first region of the second kernel address space to a first region in a device memory space, and map the first region in the device memory space to the first region in the first physical address space;
wherein the system configured to enable a common shared region in both the first kernel address space and the second kernel address space for use, and create a unified kernel address space, based at least in part on the common shared region.
