2.MVME5100 Hawk MPIC IRQ9 interrupt sources may be one of the following:
MVME5500 IPMC Module Interrupt Assignments
Legacy Interrupt assignments were not maintained on the MVME5500 due to the vastly different host bridge device
GPP PIN | Edge/Level | Polarity | Interrupt Source |
11 | Level | Low | IPMC PIB (8259) Int in Slot 1 |
|
|
|
|
8 | Level | Low | SCSI Controller Interrupt |
|
|
|
|
Connected to INTA# pin
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;
GPP PIN | Edge/Level | Polarity | Interrupt Source |
5 | Level | High | IPMC PIB (8259) Int in Slot 1 |
|
|
|
|
16 | Level | Low | SCSI Controller Interrupt |
|
|
|
|
Connected to INTA# pin
Note The MVME6100 does not have any Ethernet interrupts routed back to the IPMC PIB device.
