Abstract

A system, methodology and/or computer architecture that facilitates processing device interrupts (including level-triggered interrupts) in a user-mode process is provided. The kernel interrupt handler can cause a dedicated thread in the process to wake and invoke the driver interrupt service routine. This thread can then return control to the kernel interrupt handler. In addition to processing interrupts in an isolated mode, the context switching technique could be used in any isolated environment to process interrupts via dedicated execution context methods.
