something i want to understand about irql RRS feed

  • Question

  • windows implement irql for interrupt from hardware and software

    what i want to know if irql it something into the controller (apic or pci) that Microsoft Programmed and it works  that now the controller know how to map or irql is something into the winodws system and the controller send all the interrupts to cpu (indiscriminately)  and the windows map them according to irql
