USER-MODE INTERRUPT REQUEST PROCESSING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240126593 titled 'USER-MODE INTERRUPT REQUEST PROCESSING METHOD AND APPARATUS
Simplified Explanation
The present disclosure relates to user-mode interrupt request processing methods and apparatuses. In one example method, a central processing unit (CPU) in a kernel mode runs a second interrupt exception handler that does not include a kernel address to determine a user-mode interrupt handler corresponding to a user-mode interrupt request, switches to a user mode by using a first privilege level without context recovery, further runs the user-mode interrupt handler in the user mode, and then switches to the kernel mode by using a second privilege level without context storage.
- Central processing unit (CPU) runs a second interrupt exception handler in kernel mode.
- The handler does not include a kernel address to determine a user-mode interrupt handler.
- Switches to a user mode using a first privilege level without context recovery.
- Runs the user-mode interrupt handler in the user mode.
- Switches back to kernel mode using a second privilege level without context storage.
Potential Applications
This technology could be applied in operating systems, embedded systems, and real-time systems where efficient user-mode interrupt handling is crucial.
Problems Solved
This technology solves the problem of efficiently processing user-mode interrupt requests without the need for context recovery and storage, improving overall system performance.
Benefits
The benefits of this technology include faster user-mode interrupt handling, reduced overhead, and improved system responsiveness.
Potential Commercial Applications
Potential commercial applications of this technology include in smartphones, IoT devices, industrial automation systems, and any system requiring efficient interrupt handling.
Possible Prior Art
One possible prior art could be the traditional method of handling interrupts in kernel mode, which may involve more overhead and context switching compared to the user-mode interrupt handling described in this disclosure.
Unanswered Questions
