Abstract
Embodiments herein described techniques for calling an OS service to resolve a storage access exception in OS memory space. To do so, the hardware can use an exception indicator to indicate when an access exception has been detected and then the application program can use the exception indicator to instruct an OS service to resolve the exception on behalf of the application program. In one embodiment, the exception occurs when performing an interruptible instruction issued by the application program where the instruction is performed at different times. When executing the counter update step of the interruptible instruction, the hardware can determine whether an exception is detected, and if so, update an exception indicator. The application program calls the OS service which resolves the access exception in OS memory space on application program's behalf.
