MVME5500 IPMC Module Interrupt Assignments

Chapter 3 Programming

2.MVME5100 Hawk MPIC IRQ9 interrupt sources may be one of the following: PCI-PMC1 INTA#, PMC2 INTB#, or PCIX INTA#.

MVME5500 IPMC Module Interrupt Assignments

Legacy Interrupt assignments were not maintained on the MVME5500 due to the vastly different host bridge device (GT-64260) used. The MVME5500 uses the GT-64260 interrupt controller to handle interrupts internal to the GT-64260 as well as the external interrupt sources. The GT-64260 us's general purpose pins that are configured by software to act as interrupt inputs. The following are the IPMC module-related interrupt assignments.

Note The MVME5500 does not have any Ethernet interrupts routed back to the IPMC PIB device.

MVME6100 IPMC Module Interrupt Assignments

Legacy Interrupt assignments were not maintained on the MVME6100 because of the vastly different host bridge device (MV64360).

The MVME6100 uses the interrupt controller integrated into MV64360 to manage the MV64360 internal interrupts as well as the external interrupt requests. The IPMC module interrupts are routed to the MV64360 MPP pins as follows;
