Unified memory systems and methods

A system comprising:

• a first processing unit including a first memory location;
• a second processing unit including a second memory location;
• and
• a non-transitory computer-readable medium storing instructions executable by at least one of the first processing unit and the second processing unit to:
• allocate a pointer to the first memory location, the first memory location containing data;
• attempt access to the pointer using a second processing unit;
• and
• copy, in a kernel mode that enables the copying without a user request, the data from the first memory location to the second memory location in response to the attempted access to the pointer.

A computing device, comprising:

• a first processing unit with a first memory location, a pointer being allocated to the first memory location, and the first memory location containing data;
• a second processing unit with a second memory location;
• and
• a kernel mode driver to copy the data from the first memory location to the second memory location, without a user request for the copying, when the second processing unit attempts access to the pointer.
