- DRIVER_IRQL_NOT_LESS_OR_EQUAL： The kernel memory in a PC is the portion of the total (RAM + virtual) memory allocated to the operating system processes.

The non-paged memory pool is used by the PC’s kernel and drivers, and it resides permanently in physical memory (never paged). An IRQL (Interrupt Request Level) is a hardware component in which interrupts from a PC processor are prioritized in a specific order. When a kernel-mode driver retrieves a large amount of pageable memory from the IRQL process, you will face DRIVER_IRQL_NOT_LESS_OR_EQUAL error.
