![]() Pin-based PCI device are allocated an IRQ, and it could be shared with multiple devices. An interrupt handler with an IRQ for a PCI device will get registered only during the driver initialization. For MSI(x) interrupts, the driver has to allocate IRQs and this field can be used to skip IRQs that have already been reserved by pin-based interrupts so that we don't have to share IRQs, which generally will reduce the performance. |
