Abstract

Dynamic I/O translation table allocation for SR-IOV enabled I/O adapters including receiving an instruction to transition the SR-IOV adapter to shared mode; determining, using a configuration file for the SR-IOV adapter, memory requirements for an I/O translation table; comparing the memory requirements for the I/O translation table to memory currently allocated for use by the SR-IOV adapter; based on the comparing the memory requirements for the I/O translation table to the memory currently allocated for use by the SR-IOV adapter, determining that the memory currently allocated for use by the SR-IOV adapter is insufficient to store the I/O translation table and determining an additional amount of memory required to store the I/O translation table; and allocating, at runtime, the additional amount of memory for storing the I/O translation table.
