US Patent 11176056 Private space control within a common address space

A non-limiting example computer-implemented method includes receiving instructions to switch an operational context of a dynamic address translation (DAT) structure to a new operational context. It is determined if context switching has been enabled within the DAT structure. Based on determining that context switching is enabled, it is determined if the new operational context of the DAT structure is different than a current operational context of the DAT structure. It is chosen whether to switch to a full operational context based on the new operational context being different than the current operational context. If the full operational context is used, a full space DAT structure is set up and a private space bit is set to OFF, and if the full operational context is not used, a partial space DAT structure is set up and the private space bit is set to ON.
