Web图 1-4 IRR 、 ISR 构成. 与 PIC 中的 IRR 、 ISR 不同的是， LAPIC 的 ISR 、 IRR 均为 256bit 寄存器，对应 x86 平台上的 256 个中断 vector ，其中 0~15 为架构预留。. u IRR ：功能和 PIC 的类似，代表 LAPIC 已接收中断，但还未交 CPU 处理。. u ISR ：功能和 PIC 类似，代表 CPU 已开始处理中断，但还未完成。 与 PIC 有所不 ... Webthe IRR when an interrupt is acknowledged. (Not af-fected by IMR.) In-Service Register (ISR): 8-bit register which con-tains the priority levels that are being serviced. The ISR is updated when an End of Interrupt Command is issued. Interrupt Mask Register: 8-bit register which con-tains the interrupt request lines which are masked.
Web8259A PIC- INTERRUPT OPERATION 1. IRR stores the Interrupt requests. 2. Priority Resolver Checks three registers: IRR for interrupt requests.IMR for Masking bits. ISR for the interrupt request being serviced. It resolves the priority and sets the INT high when appropriate. 3. MPU acknowledges the interrupt by sending interrupt acknowledge.

If we need to mask any interrupt the corresponding bit in the IMR register is made high. The corresponding bit in IRR and IMR are given to the AND gate, i.e. IRR[0] and IMR[0] are given to the AND[0] gate, this repeats for all the eight interrupts. china star gear lives in usaWebJan 23, 2024 · 1) The ISR returns the KDPC object to the KiInterruptDispatch so that it knows what priority the DPC is and then schedules it itself after it has lowered the IRQL using KeReleaseInterruptSpinLock but KSERVICE_ROUTINE only returns an unrelated boolean value so this is ruled out.
