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;
Note The MVME6100 does not have any Ethernet interrupts routed back to the IPMC PIB
device.
ISA Local Resource Bus
