Abstract
Techniques are described to provide the capability to halt execution of a thread by a processor and potentially lower power consumption of the processor while responding to events in a timely manner. An operating system provided system call allows for identification of events that cause the execution of the thread to resume. A processor core uses a signal mask and translation unit that monitors for the identified events. In the event an event is detected, the thread unhalts and determines a manner to process the event.
