Abstract
Examples of techniques for hardware thread switching for scheduling policy in a processor are described herein. An aspect includes, based on receiving a request from a first software thread to dispatch to a first hardware thread, determining that the first hardware thread is occupied by a second software thread that has a higher priority than the first software thread. Another aspect includes issuing an interrupt to switch the second software thread from the first hardware thread to a second hardware thread. Another aspect includes, based on switching of the second software thread from the first hardware thread to the second hardware thread, dispatching the first software thread to the first hardware thread.
