Abstract

See full text

An authorization mechanism allows a host executing a guest operating system to grant permission for the guest to directly access an adapter function's address spaces without host intervention. This access is via instructions implemented based on the architecture of the adapter function. The host also has the capability to intervene in the execution of the instruction, if desired.
