Patent attributes
An approach to virtualizing a coherent memory hardware accelerator is provided comprising creating a segment table for a client logical partition (LPAR), wherein a virtual address space is reserved in the segment table, receiving an Input/Output (I/O) request to use the coherent memory hardware accelerator, generating an I/O operation associated with the I/O request, wherein the I/O operation is passed to the coherent memory hardware accelerator, receiving a map request from the coherent memory hardware accelerator, creating an entry in the reserved virtual address space in the segment table, creating a hardware page table map request for mapping a memory address associated with the client LPAR and returning the reserved virtual address space to the coherent memory hardware accelerator, wherein the coherent memory hardware accelerator has remote direct memory access to memory associated with the client LPAR for performing an acceleration of one or more processes.
