Abstract
Systems and methods are provided that may be employed to dynamically and intelligently allocate fault resistant memory (FRM) by calculating the currently required size of a protected reliable memory region for the FRM on an as-needed basis, rather than on a static basis. In one example, an operating system, or hypervisor or other virtualization layer may be employed to calculate the required size for the protected reliable memory region of the FRM based on current memory requirements of the virtualization layer kernel and running instances of other critical processes, and then to interact in real time with the system BIOS to cause an adjustment in the reserved protected reliable memory region.
