Abstract
Within an interrupt routing structure, an interrupt handler is registered, the registering comprising storing a pointer to the interrupt handler in the interrupt routing structure. Responsive to determining that a received interrupt comprises a queuing bypass flag in a set state, the interrupt handler is executed, the executing bypassing an interrupt queueing mechanism.
Claims20
A computer-implemented method comprising:
- registering, within an interrupt routing structure, an interrupt handler, the registering comprising storing a pointer to the interrupt handler in the interrupt routing structure;
- and
- executing, responsive to determining that a received interrupt comprises a queuing bypass flag in a set state, the interrupt handler, the executing bypassing an interrupt queueing mechanism.
A computer program product for interrupt handling, the computer program product comprising:
- one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising:
- program instructions to register, within an interrupt routing structure, an interrupt handler, the registering comprising storing a pointer to the interrupt handler in the interrupt routing structure;
- and
- program instructions to execute, responsive to determining that a received interrupt comprises a queuing bypass flag in a set state, the interrupt handler, the executing bypassing an interrupt queueing mechanism.
A computer system comprising one or more processors, one or more computer-readable memories, and one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:
- program instructions to register, within an interrupt routing structure, an interrupt handler, the registering comprising storing a pointer to the interrupt handler in the interrupt routing structure;
- and
- program instructions to execute, responsive to determining that a received interrupt comprises a queuing bypass flag in a set state, the interrupt handler, the executing bypassing an interrupt queueing mechanism.
