WebIn computing, interrupt latency refers to the delay between the start of an Interrupt Request (IRQ) and the start of the respective Interrupt Service Routine (ISR). For many operating systems, devices are serviced as soon as the device's interrupt handler is executed. WebA major contributor to increased interrupt latency is the number and length of regions in which the kernel disables interrupts. By disabling inter- rupts, the kernel may delay the handling of high priori- ty interrupt requests that arrive in those windows in which interrupts are disabled.
