    Abstract: A method for testing storage protection hardware includes receiving by a non-trusted entity that is executing on a host server, a request to dispatch a secure entity. It is determined, by a secure interface control of the host server, whether the host server is in an auxiliary-secure (AS) debug mode for testing an AS entity. Based on determining that the host server is in the AS debug mode, a secure guest entity state is loaded from a state descriptor for the secure entity into an AS entity state in hardware to test, upon dispatch of the secure entity, accesses to pages in a memory that are registered as secure and as belonging to the AS entity.

    Abstract: A computer implemented method is disclosed, which includes receiving a query for an amount of storage in memory of a computer system to be donated to a secure interface control of the computer system (1505). The secure interface control can determine the amount of storage to be donated based on a plurality of secure entities supported by the secure interface control as a plurality of predetermined values (1510). The secure interface control can return a response to the query indicative of the amount of storage as a response to the query (1515). A donation of storage to secure for use by the secure interface control can be received based on the response to the query (1520).
