Abstract
Systems, methods, and computer program products to perform an operation comprising creating, by a kernel, a temporary effective address associated with a virtual segment identifier (VSID), wherein the VSID is received by a processor in an asynchronous interrupt generated by a coherent accelerator in response to a page fault generated by the coherent accelerator in executing an instruction, accessing the temporary effective address by the processor to recreate the page fault on the processor, and resolving the page fault by an operating system executing on the processor.
