Zusammenfassung:Accelerator access control whereby an application's access to an accelerator is revoked in order to allow the system to perform a system function. In one or more embodiments, when an application is executing, a credit system is utilized to provide credits for controlled access to the accelerator. When request information is received to remove access to a credit associated with the application's access to the accelerator, the credit is marked to fail with operating system interfaces. Also, in one or more embodiments, if the credit is in use for accessing the accelerator, an effective address associated with the credit is unmapped from the accelerator.
