Abstract
A system and method dynamically allocate address translation tables for direct memory access windows by donating logical memory blocks to allocate to the address translation tables. A dynamic address translation table allocation module dynamically changes the allocation of memory to the address translation tables without a platform or partition reboot. A portion of the dynamic address translation table allocation module may reside in the hypervisor and in the partition and communicate to dynamically allocate memory to the address translation tables. The dynamic address translation table allocation module in the partition may donate logical memory blocks to the hypervisor to increase the allocation of memory to the address translation tables.
