  • Interrupt servicing in userspace
    Patent number: 11385927
    Abstract: A method for handling an interrupt includes receiving, in hardware or in firmware, a request from a task executing in userspace, where the request is to assign a function in the task and state information for the task to an interrupt. The hardware or firmware records the state information for the task, and assigns defined state information for the function to an event caused by the interrupt. When the interrupt occurs, the interrupt is serviced by saving context including the state information for the task in the memory, loading the defined state information for the function into registers, running the function, and then returning to the task preempted by the interrupt.
