1. A computer-implemented method, comprising: determining an amount of a memory space in a physical memory allocated to a central processing unit (CPU) during system initialization, the physical memory electrically accessible to the CPU; determining whether a system entity is currently being executed by the CPU within the determined amount of memory space; consolidating the determined amount of the memory space in response to a determination that the system entity is not currently being executed within the determined amount of memory space; and reallocating the consolidated memory space to an integrated graphics processing unit (GPU) of the CPU during runtime, the physical memory electrically accessible to the integrated GPU.
