WebMar 15, 2024 · An interrupt request level (IRQL) defines the hardware priority at which a processor operates at any given time. In the Windows Driver Model, a thread running at a low IRQL can be interrupted to run code at a higher IRQL. The number of IRQL's and their specific values are processor-dependent. Processes running at a higher IRQL will pre-empt a ...
